Hi, Im currently using Forest Pro v. 4.1.6 in 3ds Max 2013. Im trying to render a scene with nested forests to distribute over a grass surface. When I try to render nested forests with simple objects (basic spheres) they render correctly. When I try to use grass models in the same scene they wont render.. If I change to Vray it will render.. can you fix this issue with Corona render please? or is there any solution for this? thank you for your time
