Thanks @bripiriegmail-com for the file.
It seems that the issue is that the material structure in 3dsmax is too complex. The .max and .fbx files contain material with the “VRayMtl”. This is not standard and doesn’t play well with the FBX format.
When I open the .max file and export to to FBX, I get the following warnings:
Some materials in this scene may not be supported by certain applications and will import as standard gray materials instead. The following materials are affected:
-12 - Default
-15 - Default
The following maps are only supported by 3ds Max; they will not be recognized by other applications. To learn how to convert them so they will be compatible with other applications, see the Render Map Dialog topic in the 3ds Max documentation.
You should use Standard material only in 3dsmax when exporting FBX files to be used in Transmutr, as it is not possible to recognize other material types.
