UV Pixel Misalignment?

Post by recatek » Tue Nov 16, 2021 3:34 am

It looks like under some conditions the UV alignment in UB Painter might be a bit off as far as pixel alignment compared to Blender (and Unity).

In Blender and Unity, my model looks like this with a pixel template overlay:

Whereas in UB Painter, it looks like:

You can see the texture UV displays here (Blender) and here (UB Painter).

It isn't a major offset but it can definitely throw off some pixel painting, especially when you're trying to get clean lines in your textures at lower resolutions. I'm not sure if it's a Godot issue (it might be worth putting a bug report in to them if so?) or something UB Painter is doing. It looks like it's purely a rendering issue -- if I export the mesh back out of UB Painter into Unity, the UVs work fine.

I can send an obj file of the model and a pixel template texture if it would help diagnose the issue.

Oh, yeah that's awkward.
Yes, please can you send me the obj file to support@unionbytes.de ?
This would be a great help.
I need to investigate this, because its a real problem for pixel art.

Thank you very much.
