i have a huge problem and i try it everything and i don't solved it.
I can see all the forest on the scene and it render nicely, but i some point they stop to appear on the render. I can see it on the viewport and edit normaly but when i hit render. They are gone!!!!!
The solution i try is to delete all the forest and start form scratch and it render nice again. but in some point the problem is back again!
i don't know what to do! i have a deadline!
I'm using the latest forest version, 3ds Max 2014.
Ps. sorry for my english.
Ps.(2) when i transform the forest in mesh with the forest tools it render again.
