Some Materials Not Exporting at all (Dev Release) I have been using Modelconverter to "post-process" Gmax exported models. On some models there is one or possibly more materials that don't export properly (ie don't appear in sim). On the MDL in front of me now: Multibit alpha textures, and the material in question has "Use Global Env Map as Reflection", and "Modulate by Inverse Diffuse Alpha" checked. "Allow Bloom" checked also. Opaque texture. Source File: Gmax Gamepack, 193 Polygons, No LODs, No Duplicate material Names or part names Single Multimaterial (3 FSX materials Only) If exported directly (Gmax) no problems. When opened and re-exported using ModelconverterX one matierial doesn't show. Normals not flipped. When "converted" model is opened again in Modelconverter all materials and parts seem present.
