Offer an export option to exclude normal texture maps
A new 3D export option allows for the exclusion of the normal maps used to simulate rule definition and embossing details. This applies to Collada and Packaged Collada models where not desired - it also offers a noticeable performance improvement in export time and file size.
Collada 3D export with Rule Definition enabled during export - 36 Seconds, 1.33MB
Collada 3D export with Rule Definition excluded during export - 16 Seconds, <1MB
