Problem with exporting to Unity 3d

[Mateusz Granda]

Hello,
I'm a new user to SpeedTree and I have a problem with exporting to Untiy.
In the attached sc it shows how it looks in SpeedTree Editor and Unity. I tried with 2 other projects and it ended with the same result.

There is a bug in some Unity versions where SpeedTree draw calls were limited to 16bit indices, so around 65k vertices. If your tree goes over that, you might have problems. Try lowering the poly count a bit and you should be fine.

This should be fixed in recent versions, but I will have to check with Unity.

Thank you very much just quick adjustment with Optimization and everything looks fine.
