LuxRender 0.9-dev Windows build of 14-12-2011

[Lord Crc]

Celebrating the release of Blender 2.61, I've made some fresh weeklies. I see that you can now use the "Install addon..." to upgrade your LuxBlend25 install, by selecting to Overwrite the existing install. Any feedback on this would be appreciated.

The main changes this time is that jeanphi has continued his light sampling code cleanup, and that guibou has added a direct light sampling mode to SPPM. I've done some minor bug fixing.

Other noteworthy changes is in the LuxBlend25 exporter. I've fixed the texture preview, and I've fixed the handling of output files. First of all /tmp/ will now be replaced with %temp%, and if the output directory isn't writable it will fall back to %temp%. This should help new users get going out of the box.

These builds contain LuxRender, LuxConsole, LuxMerger, LuxBlend25 and Pylux for Blender 2.6x, and LuxBlend for Blender 2.49.
The NoOpenCL builds does not require any OpenCL driver or capabilities, but also does not use the GPU for the "hybrid" renderer.

Added writeup of changes.

Hi,

Actually my light sampling cleanup is not finished, just the core part of it. I now need to clean up the users and make use of the interfaces everywhere it makes sense.

Ah, thats what I get for not reading the whole diff

Fixed.

should sppm and direct light work only with random sampler? or do i have a problem. blend 2.61

No, known issue. It SHOULD work, but any sampler other than random will crash if you enable direct light.

Thank you

Install-Addon upgrade in Blender worked perfectly!

[HoloFan]

Except for the presets theluxblend installation it worked perfectly for me as well.

But when I start OpenCL Bidir (the preset 'OpenCL MLT & Bidirectional') not only luxrender but the whole PC crashes. My System is a Sony Vaio SB notebook with a AMD HD 6630M and my driver version is 8.862.4.3-110926a-126759C-Sony.
This is the latest one you can get from Sony. The Notebook has a button which changes the Graphics-chip from the AMD to the integrated intel-graphics. When the AMD is running the Intel shows up in the device manager as well.
Maybe there is somehow the problem.
I'm using blender 2.61 stable and the latest luxblend from src.luxrender.net.
HybridPath is working perfectly....

I have some limited experience with programming and I even did once some experiments with the Stream SDK. So if someone guides me I could perhaps do some things on my own. But I will need good guidance. Because I don't even have a clue how to compile luxrender. I can program but my experiences with compiling and things like that are very limited.

One other thing: When I export a scene which is using the OceanSim of blender 2.61 there is always a message in the log like '[2011-12-22 22:11:58 Warning: 43] Inconsistent shading normals in 904 triangles'.
What does that mean? Should I do something about it?

Btw: The last builds tend to produce some kind of white dots. (see picture - you need to load it completely to see them) I don't know whether this is a known issue related to jeanphis work. But maybe I'm just doing something wrong... (as usual. )

Sounds like a driver issue then, possibly due to hybrid bidir overallocating your hardware. A program shouldn't crash your entire PC.

It means the vertex normals don't point in the same direction for a given triangle. It won't ruin your scene in this case I think, but I'd try lovering the "choppiness" parameter to 0.5 or below just in case.

The white dots are most likely reflections of the sun, which is REALLY bright. Try using the "Gaussian" pixel filter instead of "Mitchell", also some slight bloom may be useful to cover them up.
