Having a few problems here with double side materials…
I’ve just created a single rectangular object, and applied a texture to one side. Exported it to Collada with “Export Two-sided faces” not set. And saved the file.
Then set the “Export Two-sided faces” and saved again. I then compared the resulting 2 .DAE files using Beyond Compare, and there appears to be no difference (except the internal timestamps, and the texture path)
If I then apply the texture to both faces of the object, and repeat the export, with “Export Two-sided faces” set / not set, again there is no (effective) difference between the files.
Is the “Export Two-sided faces” actually doing anything?
Comparing the files with one versus two faces textured, I can see the differences which look like it creates a second object co-planar with the first. It also seems to add a lambert color in addition to the existing material, which I didn’t really ask it to do…
Are there any plans to allow the double sided material to be specified in the Collada data usingDOUBLE_SIDED 1.0
as per the Collada 1.4.1 document?
