Okay, yeah, I can kind of repro this. Actually, in the Main branch, the alpha from the spawnable take recorded cam is reversed. So, it’s white where there is nothing and black where there is a mesh. Is that the same for you?
Secondly, are you saying that in a cine camera, the alpha is not white? Is it possible you are holding out any low-density atmosphere in front of the characters?
Ok you can try and remove the PPM from the camera then. In talking with them they inverted it for something else. But we need to have another think since its messing with MRQ. Thanks for flagging! Report back how it works out for you.
and for the non-white character alpha issue yup lit was a fog card being heldout! i am putting those fog cards on their own collection and modifier (should not have been lazy and done that from the beginning ):
We’ll get the PPM removed on the Take Recorded camera in the 5.6.1 hotfix. Thanks for the flag there!
I am not sure about that line. I haven’t seen that before. Is it there if you turn off TSR? Maybe a post effect is messing with it?
For the Object IDs the pass should be consistent on disk, correct? We re-map the colors to a consistent ID when generating the pass data.
It probably flickers like this in the preview window by modifiers in the graph invalidating hit proxy IDs. Its more annoying to look at in the preview window than an actual problem, so it’s been lower on the priority level to try to find a fix.
Ok, I can reproduce this if I have the Object ID in more than one render layer. I normally just have it in one layer. I was also able to get the 1 pixel white line at the top of the alpha. I got a GPU dump with it and passed it along.
Thanks for flagging all of this! We’ll get it fixed up hopefully in time for the 5.6.1 hotfix.
For the 1 pixel line, there seems to be a bug with the Sensor Height of the render camera. In our internal cases, if we limit the number of decimal places to the hundredthousandth, it’s fine. As soon as you add a millionth place, we get the line. Software development is fun.
Interesting, I am unable to repro it with that film back. Are you cropping at all? Is there anything else that sticks out on your camera that I could try to add here?
Either way, we have a repro, and Eric is looking into it. There has to be some sort of rounding error somewhere.
And there’s no need to thank me. Thank YOU for reporting these things! It’s next to impossible to catch regressions with all the automated and manual testing we do each release.
