I download from 123D to meshmixer ready models and import them to 3DS MAX which automatically creates the materials. But when I create/paint a model and import it to 3DS MAX it doesn't create the material as it does with the downloaded models. The exporting/importing settings are the same. Also when I mix my painted model with the ready models and export to max still doesn't create materials for all of the included models. I 'm new with meshmixer and with the texture/material stuff, so maybe I overlooked something simple. I can show screenshots if needed. I would appreciate any help.
