I am writing to you because I have a problem with files to use for 3D posts on Facebook.
I had done a lot of tests all using BLENDER RENDER: file had the color and the characteristics that I had set by the nodes, everything was ok but did not have the shine of the Glossy BSDF.
Then I changed the rendering engine in CYCLES RENDER, and checking from the rendered mode it has the shine I needed, I again exported my work in .glb for posts on Facebook, but so I see it all as gray as in the picture .
A) Can you explain to me why and how to solve? B) Can someone tell me how to set a colored background?
