material problem
with a wave length of
0.00000040000000000003 m
which must be less or equal to
0.0000004 m

share scene/material or correct the value ;)

I found a bug color profile

Indigo introduces the working space profile sRGB, as required for the normal display sRGB IEC61966-2.1

In GPU there's quite a leakage when the walls are 'thin'. The light drains through the vertices. :(

Spotted that too - see attached, exported from Sketchup.

Thin walls: a NoGo in 3D modelling since 2002

But yes, would be nice if it would work out of the box!

Really? For Mental Ray and other approximative renderers maybe. But Indigo is supposed to handle this better IMO.

I am amazed people still use that type of modeling, and I can't even remember the 2002s. Yeah, sure, you will save like 6 polygons per wall, but, people, c'mon, nowadays we have so much ram we could fly to the Moon and back! :D

I tend to see this problem in such manner: If it's physically correct render engine, then you should physically correct model your scene. Just like the example with the correct modeling of a glass and a medium inside it - there has to be at least some amount of thickness. Judging by the fact that Indigo is a physically accurate render engine, and a very accurate one, I would think it actually does worse with such tricks with thin walls, glass, surfaces in general, then the biased ones. But, hey, it's just me, and it could actually be an accuracy problem within engine, who knows.

It's time to deliver that sweet 0.48 magic, guys! :D

The devs are on a bit of a vacay for a few more days I think. :)

I think you infer too much from what I said...

If you could provide some simplified scene for this, that would help the devs debugging that issue for sure!
You can send it to me via pm, and I'll feed it into the bugtracker!

Sure thing. This is as raw as raw gets.

Better save the scene in pigs format

Doublecheck your scene pixie, that "room" walls are as single sided as they can be!

I'll be damn, you're right! Well my scene is way complex, sadly :(
