In a scene I'm working on, I'm needing to render out the shadows only. No big deal, or so I think. I'm using VRay's VFB, I have Shadow in output channels hilighted, and I made sure that my shadow casting/receiving materials are VRayMtls. GI is turned off, and all of the lights are VRay lights. Upon render the Shadow channel is blank. I turned on Self-Illumination (output channel) also to make sure it wasn't a g-buffer issue. The SI channel rendered out fine. I checked the Max properties and VRay properties on all objects in question but didn't find anything out of place.
So then I make a dummy scene with a plane, teapot, and 1 VRay light and confirm that all Frame Buffer, Global Switches, G-Buffer, and System settings are the same. The shadows render out fine in this scene.
Unfortunately I can't upload the scene. I can't figure out whether the issue is something extremely simple that I'm missing (wouldn't surprise me, lol) or if there's something conflicting with the g-buffer in my scene. Any ideas on how to troubleshoot this would be much appreciated
