Bake PBR texture in Arnold or Cinema4D

[pooya_deep]

Hello everyone, how do you bake PBR textures in Arnold for cinema 4d?There's utility > bake texture but the list of AOV are not actually PBR. Like Roughness, Metalness etc..I have done so much research and still nothing. In Arnold documentation there's nothing useful about PBR.One of my crazy solution was to setup custom aov by wiring each map to aov_write_rgb node and pass-through. But it's not resulting good if you use 2 or 3 materials blended, and we always do for complex materials.Hope to receive an answer from someone.Thanks
