Hello,

I have a scene with point light, env light and a model with texture from file. I used a vopmaterial (then uvcoor, texture, lighting model nodes). The render does with Micropolygon or Ray Tracing but it doesn't in PBR or Micropolygon PBR. It's completely black. I know I'm missing somthing in the vopmaterial because I tried a quick render scene using the pre-built materials, PBR does work.

May I know what I'm missing? Thank you very much!

For your shader to work in PBR, you need to connect the yellow BSDF connectors as well.
