Wow, that's great. Have to try this out!
Wow beautiful environment. Very thorough and detailed. But I think there are a few images that are not showing up (error?). Is that just me? Interested in seeing those other pictures...
Jack. First of all, I want to apologize for offending you. We published this just to show how the tech could be used. We don't actually care about the message. But you do bring up a viable point, that for some people - this might be an issue, so I take this post down.
Zacharias Reinhardt has published a two-part tutorial on setting up a large scale forest in Blender, that is memory friendly and can be rendered using GPU in most cases. The first part will guide you through generating and rendering a 3D tree and using the rendered image as texture for an alpha mapped tree. Then, you will also add several effects to this alpha tree, so that it is interacting with the light. The second part is about faking a better ground shadow for the tree and setting up a particle system to create the forest.
