As my title says, I am trying to render something for my class and the glass textures are appearing black, when in painter I gave them a blue texture. And it also doesn't let me use transmission.
In glTF PBR, metalness cancels out transmission. I suspect Substance may follow the same logic. The idea is that metals are not transparent, so as you increase metallic the transmission is decreased. In metallic-rough PBR, metal should be mostly full-metal or no-metal... partial-metallic causes non-physical shading…
Maybe shadowing? no light source, perhaps try painting a glow & cheat it on the inside as if it did have a light and see what happens, testing stuff can help figure it out, i do not know anything bout the updated applications, but when i tried this stuff it just worked. I also did not make my own texture/material i edited…
