About camera projection

Unread postby flansrjf » Thu Oct 01, 2020 1:08 pm

I tried to use the first and last frame for camera projection.
But there will always be an edge in the black part of the camera occlusion. I tried a higher resolution, but the result is still the same. How to solve this problem in general? thank you very much

Hi,

Could you share your project with the projected map please? Hard to say without those.

Cheers

Hi,

Could you make a snapshot to spot the issue please ? I don't see anything.

Thank you.

Hi,

The line's a part of the blending due to the antialiasing. Unfortunately, you cannot avoid this with this setup. You can try to Cam-Map with other cameras that have a different angle than the one which is filming. It should vanish the issue.

Hey, I have the same issue with this lines. I don't know what I'm doing wrong in this case. I did exactly the same steps as in your tutorial about projection mapping. If antialiasing is the problem, how are there not more people with the same issue? And can you maybe go deeper in the solution you offered below?

Thank you

I have this issue with all masks I render out of Clarisse. When I try to paint the missing parts in Photoshop I get the same lines. Very frustrating as the only way for me was fixing it in post.
