When converting GSU objects my usual procedure is to 1. Use mass texture editor to rename and convert. 2. Use material editor to add _LM textures if used. 3. Export. If I want to also use the draw call minmizer, at what point should I use it? Before or after using the mass texture editor? Initial results seem to indicate that the draw call minimizer is not working very efficiently in that it misses opportunities to combine textures that would fit on a single sheet. It would also be nice to get a list of how the dcm is supposed to treat different kinds of textures. From what I've seen so far I'm making the following assumptions: 1. "Plain" textures (alpha channel not used, no night textures) are combined. 2. Textures with alpha channels and night maps are left as is. 3. Native GSU textures are converted to external textures and included on one of the combined sheets. Is that about right?
