This isn't normal.. After I did a mesh edit in blender, exported it, the entire car became no material. I have tried everything to try to fix, and not a thing has worked. I have checked the materials.cs, and everything matches the blender material. I have no idea why it's doing this, everything matches up FINE, everything is in the right folder, it's proper location, all the textures are there, etc. any kind of help would be appreciated.
I have had that happen, there has been two different reasons, one reason was mesh name / material name started with an number or contained a dot, if even one of the materials contained a dot, that was bad, everything in Blender need to be made so that there is no dot and nothing starts with an number. Then there was a case where thing just exported wrong, had to rename object and the thing that is inside that object if you go to edit mode you see other name of the object, I guess it is vertex group or something, THAT contained a dot and made it not to work, but also once there was not even that, it just needed new name. Might of been cache bit messing things up, I think.
