[Radiance-general] su2rad: problems with texture mapping

[Thomas Bleicher]

Hello Claus

Unfortunately the texture export in su2rad is not very sophisticated. It's
not a good way to produce Radiance textures anyway.

To solve your problem you can try one of the two options:

1) Select all the textured faces, right click and choose "texture -> make
unique" from the context menu. This will create six identical materials with
a uniform mapping for each face.

or 2) Use the attached script to export the cube to *.obj and then use
obj2mesh to convert the *.obj file to a Radiance mesh with textures. The
author of this OBJ exporter says it does the "make unique" step during the
export. Please note that I have not used this script myself and I don't know
if it modifies your  materials during the export.

Regards,
Thomas
