Problem with surface appearance/pbr textures

[Sairx]

So i made a model in blender and used surface appearance on it but it’s really messy. What should i do to make a pbr texture look normal. It looks normal on a cube, but on most of my models it’s stretched

In blender you need to update the UV mapping. I recommend you do it with the albedo/color image you intend to use in Roblox. What is happening is you are stretching the original cube.

A youtube tutorial is recommended.
