Hello

• To deal with textures which shows as missing in LuxRenderer there is simple solution. In material room just clik on "Image_Source" of problematic texture if it's path starts with :Runtime, then just press OK - you should notify that name changed to texture's name. Now do export to Lux.

• Fireflies on the renders - it's a bug in 0.7 release of LuxRenderer (here is tread about that on Lux's forum: http://www.luxrender.net/forum/viewtopic.php?f=16&t=4374). To get rid of it you can find one of the new weekly builds which almost eliminates this.

• If you plan to use net rendering (i've set up a pair - win xp and imac with 10.5) you have to have the same version of Lux (unfortunatelly compatible pair for win and macos - 0.7 stable - contain fireflies).

hope this helps a bit
