Hello.
I test mocha Pro to make clean plates. So, I try to use the remove option.
However, I have a problem:

Do you know why?
I hope you understand me :slight_smile:

I think I know what is going on here. You’ll want to expand your roto, it’s probably too tight on the object you are trying to remove, leaving bits of the object you’re trying to remove on the background because the roto is right on the edge.
If that’s not what’s going on, can you send a screenshot? Let me know if you have any questions.
Cheers,
Mary

Hi there,
This one will be difficult on account of the shadow beneath the statue and how it meets the ground (you can’t see behind it) and will require troubleshooting and manual cleanplates until you get it to work.
This will probably have to be solved in several passes. You will need to paint some manual cleanplates for where the struts meet the ground and possibly where you get ghosting issues.
You may need to check the 3D compensation box on to account for the slight sweep of the grass.
You might need to adjust your frames before and frames after range to be smaller, as the ghosting might be coming from the camera warp from the lens or the angle change of the grass.
You also probably want to solve for the lens of the shot if you can, using those blue struts if you continue to have problems, but make sure you save the file as a new version first. In general, you should solve for the camera warp before you do anything to the shot.
If all else fails, you may need to do some rotopaint cleanup to get everything to look solid.
