Messed up Maps

[Lucas28129185cfy6]

Hello, I would like to share an issue I've been having. Whenever I bake my model I have been having weird artifacts with it's maps and I'm unsure as to what's causing it. I put this in discussion as I'm not sure if this is a bug or me just not understanding how the software works as I am relatively new to it. I would greatly appriciate some help.

Here's the ID Map for an example as to what I'm dealing with:

Hi @Lucas28129185cfy6,

Thanks for all the details.

My first guess would be an issue with the UVs. Can you share a screenshot of the 2D view? This also reminds me an issue with .FBX exported from Blender, but it's a bit soon to say whether it's this or not. I'd also love to have more details on what happens with the other maps?

Let me know.

Actually I did export this from Blender. Could that have something to do with it?

Here's some of the other maps I have, along with the ID Map:

Thank you for sharing screenshots.

I don't know if these UVs represent the entire mesh, but the issue very likely comes from them. 

UVs are the 2D representation of the 3D mesh, therefore they need to adopt a certain shape in order to correctly represent 3D parts in a 2D space.

From Maya's website

If certain rules are not followed, issues like the one you're facing are likely to occur.

I advise to make sure the UVs are ready to be used in a texturing software and you can obviously share to me a screenshot of your UVs in Blender if you need anymore guidance.

Best regards,

Thank you for the suggestion.

I wound up fixing it soon after I posted this querstion here... though now I am encountering a different issue, which may or may not still be caused by UVs. (I say may or may not because whenever I look for an answer to my problem I keep getting suggested that the UVs are the problem). It looks like the mesh itself is anti-aliasing. Like it's blending between the two painting layers. Might you have any idea as to what is going on here?
