Not sure if this has been addressed... I'm using 2.3.3, but external materials don't really work. I can only get one to work at a time, then it throws me the 'Material is not defined' error in Indigo. Took a look through the IGS file, but I can't open the IGMESH files, it's all gibberish. I wanted to check out what materials are being applied to the mesh, because in the IGS file it just gives an <include> where I kind of expected it to be something like,
Code: Select all
<material>
<name>blah blah blah</name>
<include>..... material gets included here </include>
</material>
EDIT: I expected it to be like that because that's how it is defined within Blender: the material name in Blender is arbitrary, it's just linked to the IGM or PIGM data through the exporter.
