Vitachick, as mentioned in the "Reality User's Guide", Lux will never stop rendering. There is no idea of "completed" in Lux, you stop the program when the image has reached a level of quality that is satisfactory. Please look at the Reality User's Guide PDF installed in your Studio3/docs directory. LuxRender works in such a different way from biased renderers that you need the information in the guide. Ten minutes spent reading the Guide will save you hours of trial and error. Plus, the way Reality/Lux materials work is different enough that you cannot draw parallels between the Studio system. Without the information in the guide you will not be able to take advantage of all that Reality offers to you.

Nevertheless I'm glad that there are no issues and that the program runs on your machine.

All the best.

Paolo
