DWG import...objects are Fluorescent?

[Giovanni]

Hello,
I am trying some simple scenes with Vray.

I link a DWG in VIZ4.

Then I set all geometry to a default white material.

Then I set up Vray with default "medium" GI (I have the free version).

The geometry seems emitting light, as if it was fluorescent.

Very weird lighting...

Also, there are no lights in the scene, and when i go to viewport "configure", and use "standard light", one or two, I get totally different results. I thought those settings were designed for the real time preview only, and would not influence the renderings.

How do I disable those lights? (those may be causing the overexposed, fluorescent geometry). That is, how do I use ONLY vray GI?

Thank you

Regards,

Gio

can you post the image???

did you try exporting the dwg instead of linking it??

Well, incredible as it is, when there are no lights in the scene, the viewport default lighting is always on.

So, the scene was overlit because of the GI plus the non shadowed default viewport lights...

Go figure...

Thank you

hello!

try this one.

put a standard max-omni-light into the scene.
then turn it of.

it works for me...

so long

why do that when there is a perfectly good switch to turn off default lighting in vrays global peramiters. Adding an omni and turning it off gives you a black viewport

Check your Ambient light setting in the Environment dialog. It should be black.
