Speedtree issue with 4.7

Hello everyone!

I have an odd issue with Speedtree in 4.7.
When I load in a Speedtree everything works just fine - including wind and all corresponding animations. However when I go into the material setup for the tree the Speedtree Node for the World Position Offset throws an error.
“[ES2] (Node Speedtree) Node not supported in feature level ES2”
So I am basically unable to change anything in the material without loosing all the animations and LOD transitions.
Do I have to get rid of a supported Platform which uses OpenGL ES?

Thanks in advance!

Hey PeterKay -

While it is true you would lose all the SpeedTree functions generated by that node on ES2 rendering you should be able to compile and save with the error in place and it will still work on SM4 and SM5 platforms. If you want to completely eliminate the error you can set up a Feature Level Select node which will insure that the material will work on both ES2 and SM4/5 plafforms.

Basic Material Setup for Feature Level Switch:
