Fixing Double Faces in Blender

Hey all!

In this video, I show you a quick fix for an anomaly with 3rd party models - double faces. My guess is its for double-sided faces and Blender puts in 2 - it's just weird, BUT, no longer do you have to spend excess time trying to solve it - here is the solution!

This code is the validation function. Somehow, this gets rid of the problem:
C.object.data.validate()

Have a super day!
GOD bless you! :D
