Is there a way to render hypervoxels as alpha black? I set it in the object properties of my point cloud and no love. I'm using points and hypervoxels as bushes and am now rendering a layer separate that needs the bushes to be alpha black. :(

I'm sure I can work around it, but I did a search in the forum with no luck and can't seem to find a way, so maybe I'm missing something.

I've always rendered a black and white (or RGB) matte and comp it, but I don't know of a way to get a black alpha out of hypervoxels.

Hum. Ya I could make the voxels black, and the objects I want to see white and run it as an RGB pass to use as a matte layer. Basically another render of all the hypervoxels to get that alpha.. It's a good idea.

I think that'll get me through this shot. Right now I'm just rendering it w/out the bushes alpha'd out and I'll just see how it looks, if you can't tell.. then I'll just skip it all together haha.

Thanks for the tip Dan
