Building Trees on Max Made land!!

Hi there

I has a small terrain that is built in 3ds max and would like to place some trees and grass onto it, however, for some unknown reason unity decides that it doesnt want to allow trees to be generated onto this max made land so any ideas please would be appreciatated!!

Thanks

This is due to the terrain system working independently from the imported geometry system. you can export a z-depth render of your 3dmax model and import it as a RAW heightmap as one option…
