It’s a simple test with dome light + hdri map in various light situation without vray sun & sky
Hdri map: Aversis, self made …

Pretty nice! Although, the night version has a green hue which seems wrong.

It’s not perfect night hdri on the last image…
Hvala majstore!
Really love the 1st one. Been playing with similar setups lately myself.
The water is very nice on the night shot, nice touch.
does anyone know a tutorial for this type of thing, Im always trying it, and it comes out weird.
Well, there’s nothing really complicated. Just use white gi + vray dome light with any mapped hdri. Change intensity mult. to 1.0. You can also set dome light to invisible and to check “full dome” if your hdri is 360 deg (with “floor”).
Paul,
I have been trying this and its not working for me. I must be doing something wrong, i cant see the hdri map (invisible is not checked). The hdri does light my scene, there is light in there, not as much as there is in alex’s image. What other settings do i have to check for this to work, do i need indirect illumination?
As i understood you can render a scene with vray dome light only, no need for indirect illumination whatsoever.
Can you help me out a bit?

Ok. So here’s da test scene. And some pics, where you can clearly see the difference between pure domelight and gi+domelight.
Test scene build in max9 x64, with sp2 and lots of renderslaves So you should lower the settings. Every scene rendered in a 1min (domelight only) and 1m11s for GI + domelight.
Will this open in 3ds max9 32 bit? If so i will have a go tomorrow, i dont have max9 on my machine.
Thanks for the effort.
Eric, it depend on camera exposure too, so in my case I have hdri map between 20 and 80 overall mult in VrayHDRI map
Yeah i figured something like that, it blew out my entire render, so i still don’t know what is going wrong in my scene. I will see what happens with pauls file.
Why do you need to change the GI to white? If you don’t turn on the override does Vray pick up the GI from the dome light’s HDRI instead? Just wondering how best to get the dome light’s image to light and colour the image realistically etc.
Thanks,

Dome light and GI - different things. Dome light doesn’t produce GI at all. It is a mapped vraylight. So, if you need fast domelight rendering + no spots from low gi settings (when you mapped hdri in background slot) - use simple colors for background color. I showed the difference above.
I saw the difference in the images, but I saw “no GI” versus white GI - I thought it was possible to do the GI with the HDRI as a third option. So, just to be clear: if you load an HDRI in the dome light then it only affects direct light colour/brightness, not the GI from that light? In that case you would *have* to add the same HDRI to the GI override in order to get “realistic” GI with that light - is that correct?
Thanks, sorry to be a pain.

Yes. But you have to set irrmap settings to pretty high, to avoid splotchiness. My choice is white gi and low settings to blur gi solution. Just to add second bounce feeling.
Okay - thanks for the added clarification!
