Blender 2.57.1 lux render

hello. I downloaded blender 2.57.1 with lux Render from

however. even after telling blender where i have installed lux render, when i click image all i get is a black screen after about two seconds of rendering. what have i done wrong?

Hi… Maybe a dumb question… But have you lighting and materials set up?..nothing to render if you don’t… Also… I think Luxrender default display is 10 seconds

i have tried to render the default scene. i get the same black screen.

The default blend is configured for blender’s internal renderer – don’t expect it to work with anything else (materials & lamps especially – most renderers use their own stuff for these aspects). Look here for a number of tutorials on luxrender:
