I have a wall with a PBR texture i downloaded, but the wall is not a perfect cube. its smaller on its width than its length, and therefore my texture is kinda squished on the small side.

Additionally i want to cell fracture the wall, but that brings the same problem, just the same textures just that everything is different sizes and squished.

How do i fix this?

There are 2 things you can do to improve the texture "stretching" - First, select your object in object mode, press Ctrl + A and select "scale" (likely not needed, but removes this from the equation).

Secondly, in edit mode, select the whole mesh, press U (unwrap), and select "cube projection". This will "create" your UV map. based on a cubic bounding box. It may not be perfect but it will be a whole lot better. The better way would be to mark seams and unwrap manually, but that could be overkill for a simple shape.

  • $\begingroup$ @moonboots If you say this so that the unwrap projects all these UVs within one space, this is not needed since the introduction of multi-object editing back in v2.80. You can just select all those objects and enter edit mode to unwrap them, no object destruction needed. $\endgroup$
