caching growfx system

15 October 2011 - 06:18 AM

Hey all,
I am trying to skinwrap a mesh to my animated growfx tree. Unfortunately this doesnt work (because it is not really a mesh, but a procedural system?).
So I am trying to pointcache the tree, but it won't do it, because there is a change in the pointcount.
All that's animated on the growfx system is a wind animation, no vertices are beeing generated.
I turned optimize off in all my growfx meshes.
Any idea what could cause the pointcount change?

animating growing grass

16 July 2011 - 08:36 PM

Hello there,
I am animating grass growing on a plane and the density is based on vertex color. This works fine, but my vertex color map is actually animated: the plane starts out black and the white vertex color blends in, starting at the border of the plane and creeping towards the plane center.
I also use an instanced mesh for the grass, this mesh has a grow animation.
The problem I have is that I can not trigger this animation in the above setup with the animated vertex color. It uses the global grow animation, it doesn't start the animation when a single blade of grass starts to grow because of the vertex map. Is there a way to do that?

Suggestions are much appreciated!
Thanks guys!
