View Full Version : How avoid instances overlap geometries

12 December 2010, 03:49 PM

This is the simple setup of my scene in Vue9 (Learning Edition):

-Assigned to the default Ground object a Dynamic Ecosystem Material called "Country Town" from the library
-Import and .obj geometry created in 3dsmax

What I'd like is that the trees populate all the ground geometry except where the .obj geometry is.
Right click on the imported .obj geometry then "Hide from render", so once launched the render I'd like to see the ground object covered by trees except where the hidden .obj object is.

How can I obtein this?

Thanks a lot!

Hi ossosso,

I would first try experimenting with the 'Decay near foreign objects' setting found within the 'Density' tab of the material editor. You could also try using images to define your ecosystem population instead of geometry too. This tutorial from Geekatplay should help:

Hope that solves your problem.
