Well, it's been a while I did something with Luxrender. I think it was in the blender 2.3x days.
However since then much has changed, so now I'm running blender 2.58a with Luxblend25. As with blender and its new interface, it's a bit of a puzzle to get going again with the new luxblend25. I like how it is integrated in the blender interface, but it makes it a kind of adventure to get help from the 'old' 2.49 tutorials.
The biggest puzzle at the moment seems to be the use of the luxrender buildin procedural textures.
Take for instance the brick texture. I think I figured out I have to use the color version for the teints and the grayscale for the bumpmap settings in the material, but somehow I cannot see any bump in my testrenders. When I try to get smart I get Error 41 and Couldn't get float in texture 'bricks' or something like that when I add the color version to the bumpmap setting, that's why I changed to grayscale that doesn't have this error. But, as said, no luck with that either, so how is this supposed to work?
