How to fix texture issue in blender

Hi there, so I’m currently struggling with some texture issues while importing models from Roblox Studio into Blender.

it makes like a lego kind of texture. If anyone knows how to fix this issue I would really appreciate it.

When you mean a lego kind of texture do you mean the old roblox brick material? Also are you using a image texture or just principled bsdf changing the paramaters?
