Has anybody ever had an issue using the Gmask tracer, where the output is just black? No roto or tracer shapes showing, however, (when using the tracer), I can see it when pressing F8. It’s only just started doing this and it’s driving me crazy. Works fine in the MK, but not on it’s own. ---

Do you have a matte output like in action? This caught me ought before. ---

Could it be that you don’t have any nodes selected for your Output? Can you go to the Output menu and make sure that All Objects is enabled. ---

Matte output is selected and all nodes is enabled. ---

I’ve had this happen when using multiple outputs before. I don’t think I was able to fix it directly, but I just copy+pasted all the nodes into a fresh Tracer and went about my merry way. ---

reported in Oct 2019…this might be a different issue though.

Yeah, different issue. I don’t lose the splines, but my output is black. Workaround is doing it in the MK. ---

This happens momentarily with me sometimes. I believe checking if it’s showing comp or matte output fixes it. I think it’s space-1 and space-2 to toggle it. When I get confused I just put a mux after it and see if the mux is getting the matte. ---

Just bringing this back, It’s still happening, but I noticed while working on our other flame , which is HP as opposed to the one that has the issue, which is a Dell. Shouldn’t make any difference, should it?
