Quote - I ran the scipt first. Let me clarify something; I did not have this problem at all. Then, around the time I first ran VSS I noticed that NONE of my png or tiff exports support a channel--whether or not I am using VSS. From you responses I gather that my problem has to do with something else. Thanks.

VSS can't affect the background. There has to be something filling your render. Are you using an environment sphere or some other prop that is filling the render?

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
