I applied material to my 3D Part in 3DEXPERIENCE CATIA Part Design app. When I export the CAD part to local computer location as CATpart through any version (from old to newest CATIA V5-6R2019), on re-importing I do not see the materials defined and assigned.

With CATIA v5 (old local PC version), if you save a CATpart locally with materials assigned in any CATIA version, on re-opening you could see the materials assigned properly. However, why don't I see the same with 3DEXPERIENCE, how can I transfer the material information to a CATpart saved locally?
