Quick Diagnostic Solutions

Non-Uniform Scaling on Transform: If your GameObject scale is X: 1, Y: 1, Z: 5, the texture stretches 500% along the Z axis. Freeze transformations in Blender/Maya (Ctrl+A → Apply Scale) before exporting FBX.
Texture Wrap Mode: If textures pinch at UV borders, select the Texture in Project window and set Wrap Mode from Clamp to Repeat.
Normal Map Type: Ensure normal textures have Texture Type: Normal Map in import settings so Unity decodes the blue channel tangents correctly.
