LuxRender 0.8-dev Linux build of 14-09-2010

[SATtva]

Hello everybody,

Unfortunately, I don't have much time for the usual progress report, please see changelogs below for an overview.

As OpenCL-less compilation is currently broken, below are only OpenCL builds. Once the problem is fixed (and I have some time), I'll update this post for regular builds without OpenCL support.

Lux 0.8-dev branch (with OpenCL):
32-bit, SSE only
32-bit, SSE, SSE2
64-bit, SSE, SSE2
64-bit, SSE, SSE2, SSE3
(If you get "Illegal instruction" error when starting the program, make sure your CPU supports SSE instructions set this particular build was compiled for. If the program won't start because of libOpenCL missing, make sure you have ATI Stream SDK installed.)
(If you receive "/usr/lib/nvidia-current/libOpenCL.so: no version information available (required by ./luxrender)" warning, ignore it -- everything should work correctly nevertheless.)

LuxBlend 0.8-dev:

Hi, nice process, first tests here.
OpenCL devices are identified but render aborts with:

I try different render settings but no success. Do i have to change the default.lxs by hand? (exporter issue)
Or is this my system, i don´t have ati stream sdk installed btw..

Thank you and cheers, mib

IIUC, you can either switch to Classic rendering engine, or use Hybrid with Path integrator with the following settings (note one and none):

[mib2berlin]

Ok, this is working, saved as preset.

Thank you for fast response, mib

Yust for info, after start rendering luxrender takes over 90% of my ram with a simple scene
and my system starts caching and lagging.
In classic mode the scene takes 4% ram.
Testing further.

Hi SATtva,

Is there any chance you can start including pylux for python 3.1.2 in your weeklies ?

[SATtva]

I do include it, Doug. For quite a long time already. Well, since Jens noticed I've been compiling them for Python 2.6.5.

Sorry, I hadn't actually checked myself

Hi !

I am new to luxrender, but the recent news of blender integration made me want to take a look at all this by myself.

It is all amazing stuff ! congratulations to everyone who make this possible !

Regarding my installation, everything went smooth, excepted for a problem with the build posted in this thread and GPU+CPU hybrid rendering .

I get the following error, either in internal or external :

As a side note, I had to recompile blender against libpng 1.4.3 to have things working here ( fedora13 32 bits )

I'm not sure how to deal with the LightSamplingStrategy thng, I don't get an option to set this .
The "Surface integrator" advanced checkbox doesn't trigger more buttons, maybe this is this.

Not sure how to trigger it in LuxBlend but it is a SurfaceIntegrator option to add:

"string lightstrategy" ["one"]

Anyway, hybrid renderer is still tracing only 1/3 of rays on the GPU (on average) so it is still quite useless.

[woah]

referring to this post just above ) : viewtopic.php?f=30&t=4563&p=48133#p47829

there should be a button to set this, my setup doesn't show the button next to depth :
