LuxRender 0.9dev Mac OS X 64bit - Oct 26th 2011

[J the Ninja]

It's weekly time!

Changes since the last build:

-The layered material is here! This material takes up to 4 other materials, and combines them into a stack. Each material has an opacity for its layer. You can use this to make arbitrary multi-layered materials

-The "Show Side Panel" shortcut has settled on command-option-I

Changelog: http://src.luxrender.net/lux/shortlog/

____
Known Issues:
-Hybrid bidir. isn't finished yet. It still has several errors, and is missing several important features found in the regular bidirectional integrator (all-uniform light sampling, MIS, tracing shadow rays through null or arch glass, to name a few I understand)

-SPPM images are darker than the other rendering modes, and oddly seem to grow darker as the renderer runs.

-Layered does not properly handle specular mats, and has some performance issues
____

There are two builds, one is the "normal" build, other other a special optimized build. Let me explain these two a bit. The normal build uses the same settings that all the OS X weekly builds have been using for about a year now. They will run on any Mac that has a 64bit CPU and is running 10.6+ (the notes say 10.6.8, this is a reminder to keep your machine up to date.) The other build is my personal build (meaning the one I use myself), with a whole bunch of optimizations for my box turned on. It won't work on everybody's Mac, but it should work on any Mac that; A, has a Core i7/i5/i3 or equivalent Xeon CPU, AND, is running 10.7. ("equivalent Xeon" means the 2009 and 2010 model Mac Pros. If you have a Hackintosh, well, the technical reason is that this build requires SSE4, figure it out from there)

If you aren't sure if you can run the special build, or don't want to bother, just download the normal one. Although, the special one should be a bit faster (5-10%, I think, been awhile since I tested it).

So without any further ado…

Normal build (10.6/10.7, 64bit only): http://graphicall.org/78/
Optimized build (10.7+SSE4.1 CPU[Core i7/i5/i3] only): http://graphicall.org/148/

Thanks J!

What version of blender are you doing your testing in? When I try to construct a layered material, although I am using a glass as my first layer, blender crashes and I am using the latest 2.60 trunk from graphicall.org

[nemasis]

I downloaded the layered materials .blend posted by SATtva and was able to render out the scene. What i was doing in the texture settings for each material was setting "Type" to none and "LuxRender type" to image map and this was causing blender to crash. Not sure if this is a bug or if I was just incorrectly setting up materials. I can send the crash report if needed.

I haven't posted it. Maybe you meant paco?

[nemasis]

You are correct it was paco's...you had just linked to it in your release announcement

Nice work! the only problem is that when I go in to the render panel, and choose the path to Luxrender, and then going back and hit the render button, nothing happens!
is this path correct? /Applications/luxrender-osx64-optimized-lion-3344/LuxRender.app/Contents/MacOS/

And when this is fixed will I automatically get a preview of the materials?

thanks, and have a nice day.

You want the path to LuxRender.app, not the executable. So just /Applications/luxrender-osx64-optimized-lion-3344

Material previews need pylux, which is also bundled in. Just find your luxblend25 folder (that should be ~/Library/Applications Support/Blender 2.60/scripts/addons/luxrender) and toss the pylux.so and liblux.dylib files from the zip in there. Then restart blender, you should have previews and internal render mode.

Wow thanks a lot but it still doesn't work, ( not negative meant ) what you said about the luxrender.app that I should do /Applications/luxrender-osx64-optimized-lion-3344, I already did this before you replied .
I also tried different ways but it didn't work, could you take a look on the photo that I attached?

And thanks for the quick reply, I really appreciate it, I always feel like "i'm the pain in the ass" on this forum .

cheers
