I was doing some unioning so the texture would be flush and this happened.
Thats… weird. although its having the effect of when textures overlap each other. Just seperate it multiple times, because it might just be you duplicated the union multiple times, and the textures of those unions are overlapping. If so, just delete the unneeded parts.
If that doesn’t work, try make the model with wedges/triangles instead.
Small update, I tried just unioning one part, I still get a similar issue when I am just using one part. https://gyazo.com/a602ed22e46a92ebe67dde0f9faf306b
Try making it a mesh in blender. it’s free. the shape there isn’t exactly hard to make
or it’s a problem with the texture.
