Vray Sky + Vray PhyCamera + Environment BITMAP issue

[paneli]

When I configure Vray Sky (Linked with Vray Sun), I pull the Sky into GI environment as Skylight.

Also Vray PhyCamera F/ 8.0, Shutter 180, ISO 100.

A Vray Sky for Reflection/Refraction in GI Environment.

The same Vray Sky for background Environment

 

It works well.

 

But,

when I replace the Vray Sky with a Bitmap (only in background Environment and Reflection/Refratcion) the sky turn black, although its still configured in GI Environment (skylight) override.

 

Anything to do with it? (I want to place a bitmap reflection in the windows, but as soon as I try that... you see)

 

LWF is correct, I guess.

problem is the exposure control in the physical camera. A bitmap background isn't as bright as the vraysky. Turn off "affect background" in the vray color mapping rollout.

Oh, I get it.

But if I turn the exposure down, I see the sky perfectly but everything is burned.

If I turn off "affect background" in the color mapping rollout I see the sky, but the Reflection/Refraction is actually what I need.

 

I managed to put an HDRI instead (I had to incrase the multi to 70 - is that correct?)

and it worked fine. But still - what about bitmaps?
