Non-paintable triangles in exported texture

[jupp2000]

Hi all!
If i export a model with texture for painting, i always get triangles, that can not be overpainted.
So that issue is in every textured model.
Please take a look at the images of the texture paint process in blender.
(It´s not only Blender, same issue in other painting apps)
How can I fix that?

- Zephyr Lite 7.531 - Image has approx. 1,2M Triangles

Hi jupp,

it's probably due to how the texture has been wrapped. You should be unwrapping your texture (ideally, manually) when doing postprocessing like this.

Here's a quick tutorial that I hope helps! https://www.youtube.com/watch?v=rvXBzw2PVMU

Hi Andrea,
but the issue already exist in Zephyr, so i am afraid, a 3rd party unwrapping would not fix it (i already tried that).
You can see some triangles in Zephyr, that are looking strange. And exactly these triangles have that issue.

I made a quick test in the meantime, and i think, it has something to do with "sharp creases"
If i totally smooth the model, there are much less non paintable triangles.
The only one, that remains in blender, has a sharp crease in Zephyr in that area.
--But of course i loose all of the detail--

With wrapped textured it's a common workflow that you need to unwrap/rebake the texture for painting I'm afraid. It's the nature of wrapped textured, some triangles will not be paintable until you properly unwrap your mesh. But I see from the discord you managed to do it, glad to hear it
