Hi,

I've been fiddling a bit with tessellation in my benchmark tool, and I'm sad to say that I can't use it at all.

It seems to affect all objects, including vegetation (lots of alpha planes), and this is completely killing my performance. Just enabling it (not on terrain) with a super low density (lower than 10) brings my fps down from 30 to less than 1.

Why is it so bad for transparent meshes? Is it possible to disable it for certain mesh parts/alpha meshes?
e.g. I don't want it on bushes, I don't want it on leaves, but I do want it on the tree trunks.

Thanks!

You can call D.setGetShaderFunc
and inside it provide a callback that will disable Bool allow_tesselation for desired meshes/materials

Esenthel: Thanks! That helps a lot.
