Hi

So I've imported my mesh into uvlayout, flattened everything, and i noticed that there's one piece with a blue dotted line.
I understand that it's a poly with reversed normals.

Is there any way to "update" the model if i go back to cinema4d, change the normal of the piece and load the Obj again?

Cuz, I'd hate to cut and flatten the whoooole model again, just because this one piece is not working.

Also, in UV Mode, I can't attach said piece to the surrounding pieces. (and by "attach" i mean: weld) It's actually not a big deal if the piece is flipped around, seeing as I'll put hair over the mesh/insect's body anway.
Is there a way to weld it to the rest of the body with its normals reversed? (aka: how do i edit the blue seamed lines? I can't cut them, or even highlight them at all.)

Greetings,
LeJ

PS: OK, there's the obvious "update" button.

but when i load in a new obj, with everything fixed, it doesn't actually update the mehs in uvlayout. there's still the blue dotted line.

I double checked by loading the same (fixed) obj into a new uvlayout file, and voila, no blue line. So the new obj is indeed fixed.

but i really really need the "old" file to update.

Yes, the blue dotted line is there because the adjacent polys at that point have a different vertex order in the OBJ file (i.e. one will be clockwise, the other anti-clockwise). There's no way to fix this within UVLayout, so you'll need to do that in C4D.

If you've already half flattened the mesh (it sounds like you have) then Save it out as an OBJ file. You only need to use Update if you want to preserve things like normals or shading groups.

So load the OBJ into C4D and fix the offending polys, save it back out as an OBJ then load that into UVLayout with "Edit" selected in the Load Options window. The mesh should come back in with all of the UVs you had done earlier but with the dotted line gone if you've flipped the normals on those polys correctly.

If the above doesn't work, then check the OBJ import and export options in C4D. As a test totally independent of UVLayout, make something in C4D that has UVs, save that out as an OBJ, then load it right back in again. If there's no UVs, then something is wrong with the C4D OBJ import or export options.
