Whoops, I should have checked that. You can imagine I was a bit
surprised when my project suddely turned blue so I didn't think of how
it could have been noticed before,

Maybe, yes :-). At least it seems mostly harmless.

Build-extrusion has some more issues, I noticed. The normals behave a
bit odd for my states, and there is one case where they are clearly
wrong. If you make a extrusion based on build-circle-points then a
texture applied to it will apply correctly, except for one "section"
which will apply the same texture except flipped left-right. This can
be fixed by appending the car of the circle-points list to this list.
However, in that case the normals at the spot where the circle
start/ends will be.

I have a example of this, forming a bottle with a label, but the lable
texture is a bit bigger than what I'd send to the list.

Yours,
Kas.
