HDRI Backgrounds

[nildoe]

Hi Guys,

I Have a quick question (I think)

Not long ago I started to Play with HDRI lighting..and right now I DONT WANT ANYTHING ELSE when lighting

But what happens is..everytime i use an HDRI to light my scenes the HDR image shows in the background...is there anyway to avoid this (I mean not having HDRI in the background but still use it to light the scene?

The work around for this right now that i found is to composite it l8r in Combustion...but im sure there must be an easier way...

Ok, one other question...from what i read so far (which is not that much) I understood that HDRI r more suitable when we want to light exterior scenes...is the right?

Thx

use the HDRI map in the vray skylight slot, not in the max environmet

For the second question, as far as I discovered, the rendered result with an hdri map (speed/quality with the given settings) is strongly depends on the number of the lights contained the map.
More lightsources (indoor) -> more accurate GI-settings you need -> slower
Less lightsources (outdoor - sun) -> quess what...

btw Someone could propound it exactly...

Best regards,

in the render dialog. under the enviornment tab section.

under environment tab -> GI environment (skylight)

If you don't know about it yet, there is a site vray.info for basics like these.

Look for the environment rollout in th4e render settings dialogue to find the slot your looking for. Don't forget to look at the reflection/ refraction slot under skylight. It is very important for nice HDR specular. One other thing, there's an Environment slot in the VRayMat that serves as a local version of the same slot I just mentioned.

is lighting with the hdr map pretty simple, just plug it into the skylight slot and render with an exterior light, or is there more to that.

where do you get these maps at for lighting exterior seens nildoe?

Thanks!
