Hi,

I am wondering if there are any video game foliage experts here? It is hard for me to find good tutorials on the subject.

Is anyone interested in starting a discussion here?


I've included a couple of pics of a small shrub I recently made, as well as a link to download the actual .lwo file.

Please feel free to critique this and give any tips/suggestions for improvement.

I am especially interested in what the proper technique (i.e. the size and shape of the alpha planes/meshes) is for creating a schub of this size is, and what the triangle count should be.

I would also be happy to hear any texture tips.

Note: I already know about the sloppy edge on my alpha texture, however, I would welcome any other texture tips!

Great question. I haven't found a really good, all-purpose answer for this yet.

I made some variations on yours with different settings.

Sorry about taking so long to reply,

Thanks for the variations you made, I like number 2 the best.



Speedtree support for lightwave.

Thank you, I'll try the speedtree demo


Here's an image of my plant in Unreal 4

Unreal has a nice two sided foliage shader with translucency, similar to unity's tree creator leaves shader.
No changes made to the asset, the only difference is the shader and engine.


Does anyone know what a rough triangle count is for small shrubs like this on current gen (PS4, Xbox One, etc...) hardware?


I think for my next attempt I will try actually modeling a photorealistic shrub with the dp foliage plugin, then use it to bake high quality textures (this time with a normal map!), using the workflow shown in this tutorial.

Thanks for the help!
