Weird Repetitive Pattern

[alayshoo]

ArmorPaint version: v0.2 -2024.X

OS / GPU model: Windows / RTX 3080

Issue description: Hi, I started using ArmorLab just a few days for a project that requires lots of textures to be created and the image to pbr textures feature was appealing to me but now I'm seeing a weird pattern emerge when I run the diffuse textures through ArmorLab. I've seen this accross multiple textures. It is most noticeable in the normal maps, some examples below:

Hello, I just wanted to write that I also noticed the problem.

I have written an updated pdf guide on compiling ArmorLab and performed some tests. "Compile ArmorLab" (2025-04-07) --> http://e.pc.cd/4Huy6alK (Immediately displayed in the browser + download possible)

" 'Photo to PBR' node is based on work by: https://github.com/junyanz/pytorch-CycleGAN-and-pix2pix "

Here is an older issue (2019-02-08): https://github.com/junyanz/pytorch-CycleGAN-and-pix2pix/issues/518
This looks similar to the problems in "Photo to PBR".

I have no idea how AI models work or how they're trained. But it seems that "Photo to PBR" is often completely overwhelmed by the source material. :(

Thanks for report and sorry it's taking so long to fix. Linking with armorlab issues at https://github.com/armory3d/armortools/issues/1502, will post about the upcoming armorlab update soon.
