I have to use matrices to draw something (to emulate the push/pop transform) but I got lost in missing docs.

I see Matrix32 has basis_xform and xform, both returning Matrix32. I tried xform, and it returned nothing with no error, and my code failed after that because the result was nil. How can I combine matrices then?

It was obvious:
mat1 * mat2

No idea why xform didn’t work :expressionless:
