Hi guys, I'm hoping that you can help me out. I have been trying all sorts of things to improve the lighting in my interior scene but I am getting massive (and I mean massive) noise in my Global Illumination pass. After 24 hours of rendering (progressive), I have a scene that looks like the light cache calculations!
My scene is huge (I am doing an entire house & environment, not just a single staged room). I have set up the primary lighting with a Peter Guthrie HDRI (so I know it is great quality), and then a VRay Sun for additional lighting information, linked to the HDRI.
I have tried with both sky portals on and off but zero difference. I have turned the windows on and off incase it was a material issue, but nothing. I have ramped up the subdivs in the VRay Dome Light to 128 which has destroyed my render times, but also with no clear advantage.
Lighting pass, specular, reflections etc... all nice and clean. Only GI that is a disaster!
Not sure what to do or what is wrong. I would really appreciate your help!
I'm using Vray 3.60 on 3ds Max 2017. My PC is Windows 10, 2x 3Gb GTX 780 GPU's, Intel i7-8720K 3.6Ghz processor, and 3Gb DDR4-2100 RAM.
