LuxRender 0.9-dev Linux build of 23-10-2011 (updated)

[SATtva]

Hi guys,

Another month has passed, so once again it's time for our regular weekly builds. Lord Crc already summed up the progress in a nice summary. Another addition not mentioned there is the new paco's Layered material, see here for an example. Both LuxBlend versions has been updated for the new material types.

On a downside, there is still no way to make all texture formats work in LuxBlend 2.5 material preview in official Blender builds, i've provided details and possible remedies here.

(EDIT: As luxrender executable was partially linked dynamically, this has lead to numerous problems with unresolved dependency libs for some people. I've updated builds, so this shouldn't be a problem anymore.)

LuxRender 0.9-dev branch:

• 32-bit, SSE: No OpenCL
• 32-bit, SSE2: No OpenCL
• 64-bit, SSE2: No OpenCL, With OpenCL

LuxBlend 0.9-dev:

• For Blender 2.49b
• For Blender 2.5x

Notes:

• LuxRender packages include Lux GUI, console, film merger utility and pylux. Exporters for Blender are separate download links.
• If you get "Illegal instruction" error when starting the program, make sure your CPU supports SSE instructions set this particular build was compiled for.
• For OpenCL builds: If the program won't start because of libOpenCL missing, make sure you have AMD APP SDK or latest nVidia drivers installed.
• For OpenCL builds: If you receive "/usr/lib/nvidia-current/libOpenCL.so: no version information available (required by ./luxrender)" warning, ignore it -- everything should work correctly nevertheless.
• To install LuxBlend 2.5 follow these instructions.

Yaaay! Thank you very much

edit: Yes, yes, yes!! Your build renders without errors
That means that I have to stick to the weeklies, but at least I can use future Lux versions

Works great on Ubuntu 11.04 64 bit with Blender 2.60

I want to rerender all my models with SPPM but this is a showstopper for me:

I get these messages on the console from luxblend2.5, I'm sure it's just debug code but wanted to point it out...

I'm having crashes with loop subdivision displacement...

this blend file used to work with older version, with this weekly testing build it crashes:

Well, that settles my personal debate about using periods in tooltips.
Should be fixed now.

Hi all,
I'm using LuxRender 0.9-dev 64-bit, SSE2, and I can't use jpeg textures in luxrender: I always get:

Code: Select all

[2011-10-25 12:17:03 Info: 0] Loading FreeImage Texture: 'Acquario.jpg'...
[2011-10-25 12:17:03 Info: 2] FreeImage error, format: JPEG: 'JPEG parameter struct mismatch: library thinks size is 656, caller expects 624'

[2011-10-25 12:17:03 Info: 0] Memory used for imagemap 'Acquario.jpg': 0KBytes

While in luxconsole there's no problem:

Code: Select all

[Lux 2011-Oct-25 12:13:41 INFO : 0] Lux version 0.9 (dev) of Oct 23 2011 at 16:51:30

With png textures all works as usual.

This is a known problem, see the link in my first post.

[GNUdo]

In your post you write about a conflict between Blender's and pylux's image libraries versions.. and in fact this happens here, too, so I get:

Code: Select all

[Lux 2011-Oct-25 12:40:39 SEVERE ERROR : 2] Cannot open PNG file 'Incompatible libpng version in application and library' for output
libpng error: Incompatible libpng version in application and library
Segmentation fault

But I get a different error using luxrender standalone, outside of Blender, and this error doesn't occur with luxconsole..

[SATtva]

Ah, i see now, thanks for clarifying. I think i know what caused this, will try to get it sorted in the next weeklies.
