interesting about making the polys double-sided. Does this mean you can give a different texture to each side?
The only app I have come across that has this capability is Anim8or - but that doesn’t carry over into other renderers. Does the UVMapper method do this - don’t suppose that function is available in the Classic version?
Rats…my elitist butt keeps forgetting I have the pro version…I just downloaded the classic and it doesn’t have the “make two sided” option in it. My apologies to all.
By “not carrying over into other renderers”, I’m guessing you mean that some renderers can’t handle doublesided planes very well, which could very well be the case. I know that adding transparency to doublesided meshes screws up poser’s renderer big time!
Making a mesh doublesided simply doubles the number of faces (and texture vertices, if mapped). The simplest mesh is defined as a list of vertices followed by a list of faces. If you make them doublesided, anim8or/uvmapper simply copies the list of faces, flips the normals, then adds this new list of faces to the previous list of faces.
Now one problem here is “UV separation”. When a mesh is UV mapped, the map tends to fill the UV plane. The new faces will inherit the existing UV map and will overlay the same UV plane. Since all the faces share the same vertices, separating the 2 sides is virtually impossible.
So before adding doublesidedness, the UV layout should be squeezed over to fit on, say only the left side of the UV plane. That way, when you add doublesidedness, a new UV layout will pop up on the right hand side of the plane. Then you’ll be able to apply different texture maps to each side.
I hope I’m answering what it is I think you’re asking…
