LuxBlend25: Download, installation instructions, issues

[AlexDS]

If you're not using pylux and integrated rendering mode and you've not asked the exporter to launch the external renderer then you won't get an image back in the render view. Check the render engine settings and report back if you're still having issues.

so, ok i tried with external renderer and check for exporter to launch the rederer, and i tried with
luxrender_0.7_qt_x64 , luxrender_CVS_20101008_64, luxrender_CVS_20100909_CPUONLY_64, and nothing happens.
also i tried with the internal renderer and that didn't work either.

Anything to report from the console? Just saying it doesn't work really doesn't give us much to go on.

internal mode:

external mode:

There are 2 issues I can see in your screenshots. (BTW, both screenshots show the same errors).

1.
You seem to have ef import errors, and yet the exporter still seems to load and function. I really don't understand that
Do you perchance have any version of python installed on your system, or do you just have what comes with Blender ?

2.
There is a condition that occurs unpredictably at the minute where the scene data is invalid at export time. I have found that sometimes just making sure I wave the cursor over the UI panels (don't even need to click anything) before exporting ensures that it becomes valid. Again, I don't know why this happens, and you're not the only one who has reported it. For now I put it down to the Beta status of blender, but I need to take this issue up with one or more of the blender developers to make sure.

Response: Yes i have Python 3.1.2 instlled from their website, besides the one that comes with blender.

Response: Cool, i hope you'll do a great job making it work. Luxrender is awesome and it is probably one of the best renderers in the world, so i would be happy to help you make it work with Blender 2.5.
About what i understand the api of blender is always changing since blender 2.5 is still developing, so maybe we should wait till the 2.6 comes up, an maybe then a luxrenderer will be makable. Just saying.
Keep up with the good work,

That fixed my issue too - move ef and luxrender to io directory instead.

Is the "combined download" available of OX X too, with pylux?

Please look in our weeklies forum for pre-packaged osx releases.

Hi, I just registered to add my list of error msgs received using Blender 2.54 linux 32 bit with luxblend25


Other than pylux is their something obvious I can do to fix the issue?

It gives an 'ef' error but also at the same time says it detected and loaded 'ef' strange. Any ideas?

Hi,

I'm under ubuntu 10.04 64-bit
Blender 2.54 beta
Luxblend 2.5
Python 2.6

here's what I get in the console after export :

1. Where can I find the pylux for linux 64 ? Because I get a black screen when I launch the render from blender
2. When I try the export the default blender scene, the luxrender console gives me that : [2010-09-15 08:29:09 Info: 0] Freeing resources.
[2010-09-15 08:29:09 Error: 28] luxCleanup() called while inside world block.

What can I do ?

Regards,

Omar

Hi guys! Sorry for my bad English, it's not my first language. I have a problem with using luxblend on my linux(arch) and unfortunately i cant solve it by myself... I'd like to use those builds from graphicall.org but dependencies on arch and ubuntu are different and unsolvable(imho). I tried to install luxblend by instructions on luxrender wiki, but it seems doesnt work for me. At first, when installation is done, plugin appears in "render" category, not in "import\export", secondly, it doesnt work i'm just getting black image and thats all. If you have any ideas what i should do, share them with me please

here what i got:

I've just been informed that this error:

Code: Select all

SystemError: Calling operator "bpy.ops.ef.msg" error, could not be found


is caused by having a blender that is built with Python version 3.1.1 or less. You need to get a blender built with python 3.1.2.

Please note that some changes have been made which require a change in how LuxBlend25 is installed.

Please check here for updated instructions: http://www.luxrender.net/wiki/index.php ... structions

Note the change for EF installation from addons/ -> modules/
