Is the 64bit fbx2edf (MAX) 3D grass bug fixed?
I have the issue with random 3D grass appearing (floating in the air or at random places around the track) and found a bug report on the KRP site where you indicated an issue with the 64bit compiler.
Thank you
It should have been fixed a long time ago.
If it isn't then please upload the track source model, including the grass texture.
