When I try to paint a model that I’ve unwrapped, the brushstrokes show up on the wrong part of the model itself, but in the correct place according to the UVs. Is there a way to completely reset the model’s UVs and relations to textures so I can start from the beginning and try to fix this? Alternatively, is there a potential culprit that I can address to fix the issue directly?
Welcome!
There are 2 potential obvious causes:
- There are overlapping UVs.
- The UVs are too close to each other and a little bit of paint spills between them. It’s always a good idea to leave a gap.
If you want to test resetting the UVs, you can use the “smart UV project” tool. It will automatically split and layout your UVs so they don’t overlap. There will be a setting called “island margin”. This adds a bit of distance between the UV islands and you will want to add a bit of it until the UVs visibly have a small gap between them.
If this fixes the problem, you will know it had to do with overlapping or distance. Smart UVs can be a bit too messy and fragmented, so if that’s a problem for your model, you would want to learn how to unwrap using “mark seam” and manually do a cleaner job.
I actually have manually marked the seams, and I know that the UVs aren’t overlapping. It’s not that the brush is working on multiple parts at the same time, but that when I brush the face it gets the shoulder. I’m trying to jerry rig a method of attaching a video of the issue since I’m too new to upload at the moment.
This should showcase the issue better than I can explain.
Are there multiple UV sets on this object?
Are there modifiers on the object?
Does the same thing happen on an other object?
Could the paint mode’s symmetry settings be related to this?
It was the first one, something I didn’t even know was possible.
