Hi everyone,

I’m Francesco and I’m a new user of the forum…nice to meet you!

I’m trying D5 and I encountered a problem when importing Rhino geometries (.3dm file without converter / just import): basically once the geometries are loaded all the materials appear “reflective”, although in Rhino no material has reflection settings( are just colors/textures in the diffuse).

Do you have any idea about this problem?
Could you help me to solve please?

Thanks everyone for the help!

Hi mate, adjust the Roughness higher and Specular lower, then it will not look so reflective.
