Object Layer IDs Dont work with Forest Pack Objects

[nildoe]

Hello..

I wanna isolate a forest pack made of grass.. If i assign an Object layer to it and use the render layer feature and select only that layer ID..it will not render at all.

HI, Multiscatter and Forest are Always rendered in ID 1....

Thanks HHBomb...but the problem arises when you want to isolate different Forest Objects in the same scene!

I have a scene with forest grass and right next to it some forest bushes... i wanna color correct the grass ONLY... how would render a pass to isolate it ? Any ideas?

One dirty solution is :
- Hold scene
- Apply Diffuse material pur white color to grass (all objects which are in Forest list)
- Apply Diffuse material pur black color to all other objects
- Render "Diffuse filter" (beauty) 128 samples
- Fetch scene...
And you have a mask of the grass...
