Hi Patrice,
The .MAX file has no matching tex maps so the materials are deficient.
The .FBX file is saved in the FBX 2012 format (I can save in an up to 2018 format). Hopefully your C4D can read it.
The .MAT material names are dummies but the meshes per se are preserved, and the mesh names can be deduced in the .OBJ file from the respective "object" (= mesh) names.
Both FBX and OBJ exports are quadrangulated as requested and are claimed to be optimized for C4D.
