Testing Vray, need visopts

@Tom, (oops, I had some hidden lights I left on that messed up the comparison, I edited this post.) For comparison, I use higher hsph subdivs in my irradiance map, and add GI lighting to increase the illumination through the windows. Something odd happening with your AA sampler selection, see the fringing?

Here is a comparison:

Yeah, I do. Odd, indeed. That's not happened to me yet. Must've erred somewhere. Biased render apps and their gazillion settings!

What do you mean? Portals?

If I had a penny every time I said this: " check clamp output and sub-pixel mapping" , those are white values, bigger then 255. V-ray just doesn't know how to represent them.
What do you say guys, Pete has resigned ?

Weird. I've rendered with both unchecked without problems -or so I think. I should delve into this as soon as I get my new machine.

Exactly right! Thanks Stefan - I didn't think to check that. Here it is with both checked.

Tom - I changed the GI from sky texture to none, and increased the multiplier to 4.5. I also decreased the sun intensity to get less harsh shadows where you do see the sun in the interior.

Nope, watching y'all discuss stuff, quietly carring on on my side.

Thanks for all the links guys.

I hope you get up to speed in time for beta to start. The next version has a bit more pep in it's step.

It's our puny screens rather - if you want to use higher bitdepth for post editing you cannot use the clamp feature. But you'll get the full range of light data.

actually, it was just the sub-pixel mapping that was needed. It renders fine with clamping off. Good point about not clamping output - even if you don't save to HDR, you can't use the levels adjustment in the vfb if something is blown-out.
