Hello, I’ m trying since 2 days to get a scene with:
- one Vray Dome light with HDRI in texture slot for the lighting
- One Bitmap map set to the environment (F8) to used as background
When I render, it is the Vray HRDI Dome texture map that came up in the background and not the environment image.
I probably do something wrong but I can’t figure out how to light a scene with one HDRI and render the background with another image (and not the one plug into the dome light texture slot)!
Ah good question, if you set reflection/refraction environment to black then your scene will reflect from your dome light. (unless affect reflections is checked.) Otherwise it will pick up your bg image, so good call there. I should have mentioned it.
Well, here are a test…that failed to proove anything.
In terms of beauty pass, It doesn’t make any difference, neither in the Global Env Override slot or in the Env reflection/refraction slot.
But when black reflection/refraction slot is tick, it doesn’t affect the teapot but the glass windows!
I probably have to raise the quality of the GI to see really the difference in the beauty pass and then see a rendering time improvement.
" (unless affect reflections is checked.)" what are you referring to?
after testing, I really thing that it doesn’t make any difference as seen below.
The test have been done in Spherical Env coordinate, but in screen mode it is the same result.
I never use this. I think when used DomeLight, background image doesnt makes any influence to GI, because its override by dome light. When you check “Invisible” option as I mention before, dome light is not visible, but its still override GI lighting as it does when is visible.
In other words - if dome light is visible, override any influence of background image + background is not visible. If dome light has invisible check, its still the same, background image does not any influence + background is visible.
