Get the Wow Factor for free

The Nature Academy just reopened. The Blender online training course for nature scenes is now 13 weeks instead of 9 weeks and the price increased from $197 to $297, but there’s a weekly payment method set up this time. That’s a reasonnable increase regarding the amount of new tutorials I think.

While you’ll probably no longer be under the first 100 participants, there is still the chance to get Andrew Price’s “The Wow Factor” book for free if you join until 14th of December. Just be sure to log in early enough because the download link will disappear later. Actually that’s not just a book – it’s a 200 MB download and includes the audio recording of the book as well as some videos. So, if you want to join, join now and get this $47 book for free…

Nature Academy for download

People coming to my website often use the search term “download” associated with Andrew Price’s Nature Academy. This could mean that they are trying to find the Nature Academy tutorials for free, or they want to know whether it is possible to download the tutorials during the course.

Well, Nature Academy tutorials are not available for free – at least not legally at the moment. And I will not make them available illegally. But when joining the course, videos can be downloaded. There’s not even the need to install a special video download plugin for the browser. Andrew just provides a download link for all the tutorials. Videos are provided in MP4 format.

Nature Academy certificate not approved

When I submitted my flower scene for the certificate of completion, I didn’t even think it was possible that the certificate could be rejected, because in the announcement for the certificate, it says:

To receive your certificate you need to apply by submitting one finished render that proves that you have learned something from the course.

Well, and I definitely have learned something from the course. Starting with a simple checkmark, I am now able to render complex scenes which I couldn’t even dream of a while ago.

Anyway, Andrew did a critique on my render which says:

  • lighting is too flat
  • the overall image is too blue
  • the sky is too dark
  • the petals of the flower are paper thin

Actually I don’t really know what “lighting is too flat” means. I agree that the overall tint was blue, because that was intended by me: due drops are more likely in the morning, so I wanted to give it a slight morning touch with my blue color. I definitely agree that the sky is too dark. I had a look at the morning sky today and it is much brighter. Thanks Andrew for this hint. Regarding the daisy petals, there are two types of daisies around: Bellis perennis (common daisy) and Leucanthemum vulgare (oxeye daisy) having different height in their petals.

Anyway, I’ll try to change the petals just in order to show that I can do it and I have learned something from the course and then I’ll resubmit the image. Actually, I am changing my scene while writing this article and it turns out that Andrew could have done the tutorial in a way which allows making changes more easily:

  • Some of the petal verticies could be in a vertex group so that the verticies can be selected at zero time. If this is done before duplicating, it would save me a lot of time now.
  • The changes in the height of the petals could have been assigned a shape key. This would allow adjusting the depth of the petals at zero time.

So yeah, Andrews critique made me a better artist, knowing what to do better in the future: thinking of vertex groups and shape keys. And I consider Andrew as a customer who – in case I would do 3D graphics as my primary job – would pay me for the results. And if the customer doesn’t like the results, I need to change the scene.

Nature Academy final review

Finally, the Nature Academy is over and it’s time for a review. First of all it was a hard choice between the Gold and Platinum membership. In the beginning, I couldn’t really judge which one to buy, so I simply went for the cheaper one.

I started with almost zero knowledge about Blender. I have just done one render completely on my own and until the start of Nature Academy, I have just watched some of Andrew Price’s tutorials but never actually modeled one. Together with the start of the Nature Academy I set up this website, so almost all content until today is related to the Nature Academy.

The beginning

Immediately after I had paid the price for the course, I received an email with my login data. This is really good, because I don’t like waiting for virtual things. On a special website there’s a lot of content available for download instantly. I have a quite slow internet connection, so the ability to download stuff is great. However, you can’t use download managers because the links will expire.

For download, there’s the Drag’n'drop collection which is a series of Blender models for use in any scene in case you don’t want to model them yourself. It includes grass, trees, rocks, mountains, plants, shrubs and skeleton trees. However, I can’t get the grass work well. I have no idea on how to import it correctly and there’s no tutorial on that.

Next, there are reference photos of beaches, clouds, fields, flowers, forests, grass, lakes, leaves, oceans, pathways, plants, rocks, shrubs, flowers, snow, streams, stumps, trees and trunks. The quality of those is ok for a reference picture, but not suitable for background images (but that is not intended).

Third, there’s a bunch of textures related to nature such as leaves, ground, rocks, shadows, skies, tree bark and also some seamless textures. This is great for people like me who have not set up a texture collection yet.

In the beginning, there were some download issues. Some files referenced wrong content. This is fixed now, so if you join the second course, everything will be fine.

The courses

Every week a new tutorial is released. A tutorial is a series of more or less videos, depending on the complexity of the scene to create. Typically, only a still image is rendered, but for some tutorials, bonus material exists which is about animating the scene.

All in all there were nine courses and the topics are grass, rocks, trees, plants, lakes, flowers, oceans, mountains and forests. The next course however will include three more courses which are rivers and streams, waterfalls and aerial shots. Andrew announced that the price will increase which is probably due to the new tutorials.

The quality of the tutorials is just the same as you can see on Andrew Price’s regular BlenderGuru website. So if you like the tutorials there, you’ll like the Nature Academy videos as well.

For me as a complete newbie, I could complete the scenes without asking additional questions. At the beginning, I needed 16 times longer than the length of the video, at the end I could finish the scene in about twice the time of the video. And finally I could even answer other participants questions in the forums.

I confess I didn’t have time to finish the animations (and I didn’t have a fast enough PC at first), so I rejoin the second course (which is for free by the way) and do the animations then.

One thing to note is that not all tutorials are purely based on Blender. There are three tutorials which make use of free 3rd party software which is Arbaro for generating a realistic tree (week 3), the ivy generator for creating ivy around a tree (week 4) and the ocean simulator (week 8), which is actually a different version of Blender. For me, using that software is fine, but if you’re already familiar with those topics, you might not benefit so much from the course.

Topics covered

The grass tutorials is much about hair particles. I spent much time, getting it right and experienced crashes due to the wrong Blender version I used (not Andrews fault).

The rocks tutorial uses various displacement modifiers, texturing and an advanced method of duplicating objects that look different when moving through space.

Arbaro is the main point of the trees tutorial. It includes lighting an outdoor scene and texturing the leaves. In this tutorial, only the tree is created. The final render should have some grass.

The plants scene is using the ivy generator mentioned before. Next, it uses array modifiers to create the leaves of a fern. Here I think Andrew could have spent some minutes on reducing render times, like I did: render times of 18 minutes or 7 minutes is a big different in my opinion.

The lake tutorial introduces reflections and fog. Modeling is limited to the lily pads, other plants are imported from the drag’n'drop collection.

The flowers tutorial is again about particles, including weight painting. Modeling is another part and for the background, alpha-masked trees are used.

The ocean simulator creates the ocean of this tutorial. Texturing and reflections are other big points. In this tutorial, the horizon is not flat, which looks a bit awkward. And actually there is a solution described by Gav Bain.

The mountain tutorial uses the ANT landscape generator which is built into Blender. Snow and mountain textures are done using material nodes, which was really impressive for me. Sculpting is also used to enhance some parts of the mountain.

Finally, the forest tutorial uses pre-modeled objects again and is about weight painting, particle systems and some texturing. As described in my forest blog post, the puddle reflections looked like melted glass and needed improvements.

The bonuses

Every week, there’s a live cast session where Andrew answers questions and does a focused critique session. The live casts last 1 hour each and after some initial issues, it worked well then. Actually I could never participate on my own, because the live cast time didn’t match my working time, but there’s the possibility to send Andrew an email and he’ll answer the question then.

The live casts are FLV videos hosted by a 3rd party provider and aren’t available for download directly. The size is at ~110 MB each but actually there’s not much to see – just Andrew talking. That’s why I converted the videos to MP3, which reduces the size to ~30 MB and I could simply put it onto an MP3 player and listen to it when I cycled home from work.

All scenes are available as Blender files for download. I think it is a good idea to have the scene available in order to review the settings Andrew made. Actually I never needed it, because I was happy with my results.

The inspiration boost is a collection of videos which are hosted on Vimeo, so not special content of the Nature Academy. So you can get that for free if you don’t mind browsing through thousands of videos to find the good ones.

During the Nature Academy, a photographer donated another collection of reference photos, the Oliver Huth collection. These photos are higher quality than the reference photos provided by Andrew; you can see that the photo was composed and lighted properly.

The forum is actually not a forum but an enhanced commenting system. It is split into four parts regarding support and questions, finished scenes, suggestions and off-topic comments. Today there are ~3500 comments posted and some of them are really valuable.

The end

Once all courses are finished, you can apply for a certificate. To do so, you have to submit one of the finished scenes you created.

In parallel, a competition starts. All participants are asked to create a realistic nature scene. The price is ~500 US$ in hard- and software. While you have to submit the picture only, the winner needs to send the Blender file as a proof.

My conclusion

The course was nine weeks of work where I spent much time and where I neglected my wife in the evenings. But it was also nine weeks of intense learning, much better than watching TV or drinking in a bar.

The tutorials made by Andrew are just great. His pronunciation is clean and good to understand for foreigners like me. Sometimes it’s hard to follow, especially the Compositor sections, but works with the pause button.

I absolutely liked the Nature Academy. I learned a lot and all the topics were quite new to me. But if you’re a professional Blender artist with several years of experience, you’d better consult someone’s review who started on the same level like you did. For all the beginners I can only recommend the Nature Academy.

So far I know only one more review, which was written by Alex Telford, who also describes himself as a newbie. His review includes comparisons of scenes done before Nature Academy started which I obviously can’t have.

Slightly improved forest scene

As announced, I wanted to improve the forest scene, so here is the next step. I exchanged the background completely so there is now a grassy meadow followed by another forest. The puddles are now on the path and there’s less grass inside the puddles so that they are reflecting much better. All stones have the same material now. And finally I added some details like the earthworm, spider and the signpost with direction to mount Andrew :-)

Forest - Improved scene

Forest - Improved scene

Here’s how I corrected the bad displacement on the puddles:

  • I removed the displacement on the ground which was done by manually editing the mesh with proportional editing enabled. To undo, select all verticies and scale the Z axis to 0.
  • Add a displacement modifier instead. Make sure it’s at the top position, otherwise the plants will be off. For the displacement texture, I used a cloud texture at size 1.5
  • Weight paint the displacement to not show up on the path directly. Use a different vertex group in order to differ from the puddles.
  • Put pebbles all over the path, including the puddles.
  • Put foliage everywhere except the path.
  • Use grass on the path but not the puddles. Otherwise the puddles would reflect the grass only.

Now as I think the scene is improved, what is your impression?

Applied for the certificate

Nature Academy has reached its end and I have applied for the certificate. The option was to apply with a render of the course or to create a render for the final competition. I’m not sure whether I want to participate in the competition at all, so I selected the flower render for the one to get the certificate for. I am excited to see how it looks like and surely post a photo of it here.

Flowers - Final result

Flowers - Final result

What’s next here? Well, the course reopens in October and I haven’t done any of the animations yet. So I will participate again (because it’s free for existing members) and go through all the animations this time. In addition, the course will be extended by three more weeks about streams and rivers, waterfalls and aerial shots; so there will be three exciting tutorials which I can follow from scratch.

Finding out of the forest

So this is my result of the last week of Andrew Price’s Nature Academy.

Forest - Final result

Forest - Final result

Personally I’m not too happy with the result as there are some issues with it

  • trees outside the forest are darker than inside
  • bright green trees inside the forest are too saturated in my opinion
  • puddles are painted at the wrong place. They should be on the path
  • stones have too different textures. Why should there be so many different types of stone near each other?

What’s your opinion? Anything else to be corrected before I go for another 25 minutes of rendering? Any feedback and critique is welcome.

These are the modifications to the original scene:

  • added grass on the path
  • using dark green vignette instead of black
  • use a displacement modifier for ground instead of mesh editing in order to use stencil on the puddles (but this didn’t work 100% as expected)

Great wide mountains

I already finished the mountains tutorial of the Nature Academy. Actually I didn’t follow the tutorial but the preview video which was available during the announcement of the Nature Academy and the tutorial which is available now is still downloading.

While I was fast with compositing due to the reusable vignette node, I am not so happy with the sculpting of my mountain. That’s probably due to the fact that this was the first time I ever did sculpting in Blender. As well for the first time I used material nodes and texture nodes, so I learned quite a few new things in this tutorials.

Anyway, the result is quite ok, but nothing special I did on my own, except that I followed my own article about mist I published before.

Mountains

Mountains

What do you think? Is there anything to improve or any obvious issues?

For me, I feel a little bit sad as this is already week 8 of the course and Nature Academy is ending soon. I had a lot of fun so far and wished it would never end. I am so excited about the relaunch in October which provides three additional tutorials about waterfalls, rivers and streams and aerial flyover.

Creating a reusable vignette node

One of the favorite effects of Andrew Price in the Nature Academy is the vignette. Almost every final render has it. The vignette effect consists of five compositor nodes and they are not really intuitive to remember. The next tutorial about snowy mountains is upcoming and so it is time to construct a reusable compositor node group.

The vignette effect I am constructing here is reusable and configurable at the same time, which means that the amount of the effect, the sharpness of the vignette and the color can be customized if needed.

The internal setup of the group and example usages with the default scene look like this:

How to use: go to File/Link (Ctrl+Alt+O), select the Blender file,  go to NodeTree, select the vignette node.

The group has four inputs: input “Image” is the picture you want to apply the vignette effect on. Input “Amount” is the blend amount and should be a value between 0.0 (transparent) and 1.0 (opaque). Unfortunately it is not possible to restrict input values at this time. The third input is “Edge” and controls the sharpness of the vignette effect. It also uses values between 0.0 (sharp) and 1.0 (soft). The last input is the vignette color, which is typically black, but can also be set to any other color, e.g. red like in the given example. You could even use an image or texture as vignette color.

What do you think? Is this nodes setup useful?
