Hi, first time writing here. I am facing this problem: I have exported amodel made in 3DS Max in .fbx, but when I try to upload it here in Sketchfab with its textures, some parts are just missing, even though all the model has the same material, or maybe 2 different materials (but even in this case some meshes are visible and some are not. The parts not visible are made using booleans, but I have already seen the "solution" changing them to editable poly, but the problem keeps going. In the 3D settings of the model the misisng parts appear when I turn off transparency, even though those parts have nothing of transparent of any type. But when they are "visible" they appear in black, and the textures are not showing.
This is what can be seen with transparency switched off:
I even changed the format for trying something new, but the model appears broken on some parts. Any idea?
