Hi
Are there any limitations for the group and object naming? My guess is the type group naming must be RWY01, VOID02 & etc form.
What about the whatever groups and objects? Is it possible to use indexing with names? Something like tex0.001, tex0.002, tex0.003 and so on?
The AC3D file format document don't mention anything against this and AC3D open the test .ac file without problems.
