I have gone through the tutorials regarding lighting, but still, am having problems. I have attached the scene with the lighting channel separate. The lights have the face as an emissive material; the light photometric is placed outside of the fixture geometry. The photometrics is set to 200W @ 148.54 lm/W at 6000K, light loss factor set to 3.4. Scene settings EV 13.31, K 6500. The rendering settings for the scene is set to interior sun and artificial, at summer solstice, 12:30 PM. Help me please!
So, you want to render a daylight image and to see the artificial lights, right?
Have you turned on the lights from the Artificial Lights On button in the V-Ray for Revit ribbon?
You need to setup the render settings in V-Ray which means: 1. turn the artificial lights on, 2. decrease the EV to something like 5-6, 3. decrease Sun intensity
Note that V-Ray will take the summer solstice sun position from Revit but not the rest of the rendering settings.
Yes, in the VFB you see all render elements. Once you save the RGB channel only, there won’t be a background.
