Smart UV Project/Unwrap I'm having trouble using the Smart UV Project Unwrap in Blender 2.81. When I go into shading to check the Unwrap, I apply a basic checker texture and it shows a stretch in the Z axis. Why is this so? How can I fix this, make them square checkers.

See below:

This usually happens, when your object has non-uniform scale.
You need to apply scale first for a correct UV unwrap.

Object > Apply > Scale



Also, make sure your texture is connected to the UV map
