About sunlit environment

[MisterD_cg]

Hello, all friends, I'd like to post this to collect the right tips by the experts to help me and all the novices to see the sun really entering a room and to have perfect control on the background/ambient image.
Any suggestion is like gold!

Thanks to all

Color Bleed/Bounce

And while we're discussing settings, can someone shed some light on color bleed/bounce? I've been working around color bounce in previous beta versions by rendering 2 images, one with the colored object and one with a white object in its place. Not the most efficient approach.

I'm not super familiar with Vray Materials at this point, having never used the program till Beta testing. So my question, is at this point in the beta testing process can we control color bounce, if so, how? What material setting am I missing?

As far as i know, there is no direkt control for color bleeding even in the 3D Studio version of vray, you can influence it by choosing different color mapping types such as HSV exponential for example, which preserves more color intensity than the standard exponetial type, take a look at the online vray manual for more information about this. Another way of influencing the amount of received / emitted light on a material basis is the use of so called material wrappers in 3D studio. Originally developed to fix problems with standard 3D Studio materials, they provide multipliers for receive GI and reflect GI, but no direct control over the amount of color which is emitted. I think the bleeding multiplier is a long awaited feature for vray.

Thanks Andy.

That helps alot. For all those people that want to see the section of the online manual here it is.

Now back to MisterD's question, He wants to see the sun really entering the room, which I'm assuming (guessing) that he is trying to show through a glass material of some kind, try clicking "Affect Shadows" in the Material Refraction Roll-up.

If that isn't what you're looking for, can you explain?

@bdcali: at the GI options are some parameters like saturation and contrast, maybe this parameter help you to get what you want.

Just for a reference, here is a real photograph that someone posted on the V-Ray forum:

As you can see, color bleeding is present to a great degree in the real world.
