ok, I think it was the LC settings. I'm doing arendering now and I'll post it when it's done.

[DaForce]

oh, you hadnt tried the LC changes I suggested earlier yet?

I did but I had a setting of .007 instead of .02 for the sample size. I must have did that by accident

[DaForce]

Ahh right.

Well post your results after this render.. so we can see how its looking

ok, that did not do it. i'm going back to basics and putting a grey basic color to all.

[Candelero]

Can you send me the scene so I can take a look into it.

Hi all,
When you solve this problem, can you please post the answer to it? I sometimes have that same problem and am very curious to find out what is creating the problem.
Thanks!

Re: dirty walls not inentional

the colo rmapping is high becuase otherwise the image comes out too dark.

what else should I do to increase the amount of light into the scene?

I know I'm late into the conversation, but have you tried using the gamma correction curve located in the V-Ray frame buffer to compensate for dark color mapping results when using Linear Multiply? see example.

Have you tried shuttong of the HDR yet?

Otherwise send the scene to Nikki... or me so we can get your render sorted out.


What bugs me is that scene really shouldnt be so dark as to require color mapping values THAT high. Its go nice big open windows..etc..etc. Maybe try putting some vray lights at the windows set to skylight portal mode or just normal invisible vray lights and lower the color mapping RIGHT down.
I honestly thing thats were the problem is steming from.

I'll give it a try.
One thing I did try is to use LC for both IR and the dirty whent away but made the lighting flat and not so realistic. The issue happens when I use IR for the firt slot in the IL. Maybe that can tell u something.

I'll try now with useing invisible vraylight at the windows and turn down the color mapping. If that fails, I'll send you the file.

Thanks for all your help.

[DaForce]

Have you tried cranking up the IR to high preset?
That still shouldnt be the answer tho, something funny is going on.

Ok, im curious to see if the invisible lights will help.

Have you tried merging the geometry into a new scene and relighting it step by step?

Its similar to a problem ive had with corrupt irradiance maps - save it out and see if it crashes the irmap viewer.

If those are true, try this:
(3) Set a dome light in the scene

Hi Candelero, may i ask what benifit this has over vray's normal skylight in this situation?

in what circumstances does one use a dome light over skylight, is the question i think i am asking.

[ene.xis]

any luck so far?

I'm still working on it in between working in some other things. I'll post an image later on.

thanks for all the input
