Problem with normals when building my own LDraw interpreter.

Things to check:

Are the type 1 line matrices multiplied correctly?

Not everything is CCW or CW it can differ per .dat, in LDCad I convert everything to CCW (flip tri and quads point order) before using the data.

How do you correct for the neg Y in ldraw? (things seem to be pos Y in your images)

Is unity left or right handed?
