Anyone know how to import an obj file w/mtl, then bake it on so you can export one file with high res color info?
MTL files aren’t standard between all programs and I think Zbrush puts out a very rudimentary version (which doesn’t necessarily contain the correct data–such as referring to .bmp files that do not yet exisit.)
For now it is better to move your maps information by hand as texture, normal, displacement maps, etc. You might make it feature request to “respect” the MTL file by opening a ticket in the Support center (mark it as “Feature Suggestion”.)
