0001231: Always black screen when rendering in Blender 2.63/Luxrender 0.9

Notes
(0003399) Lord Crc (administrator) 2012-05-13 19:12	Did you try the suggestions I posted in the forum? If so, could you turn on the console (Help -> Toggle System Console) and see if there are any error messages printed? Ideally copy/paste them here.

(0003401) Lord Crc (administrator) 2012-05-13 20:42	Ah, I see two immediate problems: First, "C:\tmp\: No such file or directory". This means you did not set the Output path correctly, check the Output panel in the Render tab and change it to somewhere where you have write access. Secondly, "Preview aborted: 'Mesh' object has no attribute 'faces'". This error means that you're running an old version of LuxBlend25. Blender 2.63 introduced BMesh which changed how scripts has to access mesh data, thus you have to update your LuxBlend25 as well. I suggest you grab a weekly build from here http://www.luxrender.net/forum/viewforum.php?f=30 [^] After extracting you'll find a file called "LuxBlend26dev_README.txt", read it for instructions on how to upgrade your LuxBlend25 (or just do it manually). Hope this helps.

(0003403) Lord Crc (administrator) 2012-05-13 22:09	"Using pylux version 0.9 (dev)" this means Blender is still using the old version of pylux (ie not the one from 1.0RC1 or the weekly), so I'm thinking it's still using the old version of the exporter. How did you update luxblend? Perhaps you need to do it manually. If you extract the LuxBlend26dev zip file that came with the weekly, you should see a folder name "luxrender". Copy this folder (the folder itself, not just the contents) to "C:\Users\Carsten EB\AppData\Roaming\Blender Foundation\Blender\2.63\scripts\addons" (copy/pasting this path into explorer would be the easiest). You should get a warning about overwriting the "luxrender" folder that's already there, press yes to that and the subsequent overwrite questions. If you did not get a warning you did something wrong :) Start Blender again and you should see "[Lux 2012-May-14 07:08:23] Using pylux version 1.0RC1" if everything is working correctly. If you used the "Install Add-on" button approach, could you please describe what you did? Perhaps we need to change the procedure somehow.

(0003404) CarstenEB (reporter) 2012-05-13 22:53	Thank you so much! It seems to be working now. :)

(0003405) Lord Crc (administrator) 2012-05-14 00:05	Great :) Could you explain why it didn't work the first time? I'd like to streamline the installation process before 1.0 release so it would be nice to know which areas we need to improve in.

(0003410) CarstenEB (reporter) 2012-05-14 09:23	Hi there, Yes I can mention a few things. 1)wrong version of LuxBlend25 2)You need to unzip the file and also install the luxrender folder under Programs\Blender\...\Script 3)How to setup Blender. I think to use the latest developer version of LuxRender also helps. I tested by installing it on 3 different machines and it worked on each one. Again, Thank you :)
