Suddenly...rotoscopes won't render

[Kelley]

Started experimenting with building landscapes, added a Ptero, and made a few dozen 20-sec. renders this weekend with the Ptero flying around. This morning [Monday] I'm trying to fine-tune things and the rotoscopes disappeared. I get a plain black background. Camera_02 had a strarfield roto. It too. is black. But, if I make a screen snapshot, the roto is there. I tried adding a new camera. It also will not see a roto in a movie render. I removed all the rotos and went with the default pale blue backgrounds. Screen shots see the blue, movies are black. I tried closing and re-starting A:M, then my computer. So far...nothing. Anyone have any thoughts on this?

 

Mid-afternoon update. I scrapped the whole choreography and made a new one. Re-installed objects and a roto. Same problem.

It sounds like the 'Alpha' is turned on in the 'buffers' section. That renders only the objects in the scene and all backgrounds are rendered looking black, but will save as the alpha transparency if the format supports it.

...and so it proved to be. [ have NO idea how that might have happened.] Thanks a million.
