Hello Radiance,

Just a quick question, I presume for GUI use I still need both downloads?

I see the much awaited resume option is incorparated.. nice...

Oh well, with adsl this was a little bit stupid to ask<g>, downloaded both, better safe than sorry. Thanks...

Hi, this is an test with exit portal and sun light, but have some bug, in the top corners of the room and at the base of the grey cube, placed on floor center. I am Sorry for bad English.
Render Time Hours 12:47 with WinXP Amd Dual Core 3,8 Mhz.

[Radiance]

Oh noes! more lightleaks...

can we have your blend file please pafurijaz ?

Thnx,
Radiance

I'm not sure that exposing backfaces to sun is a good idea anyway, is it ? In my mind, realistic rendering comes along with realistic modeling, here the walls depth is strictly equal to zero :/ In the same state of mind, there is more likely to exist a small gap between floor and objects than any sort of intersection. If two planes (floor and cube base) share the same space, how could a renderer discriminate between them ?

I'm no coder, but I believe that your modeling/object placing is not safe/realistic, pafurijaz

EDIT: to put things simply, I believe that modelers have some duty they should not ask coders to work around. Anyone correct me anytime if that does not apply here, best regards.

Hi, this is the scene.

CTZn, Yes you are right, but with indigo I not have problems.
The scene rendered, has an red spot, on top right corner.
Below another rendering.

CTZn, Yes you are right, but with indigo I not have problems.

Fair enough

I don't know if luxRnder kills short rays beneath a very short distance like Indigo does...
