Hmmm - I cannot get "Mental Ray" working, (when I select It shuts maya down ) but I have a new problem aswell, well a few....

There are these 'speckles' I think they are coming from the floor but even though the walls are Lambert and don't have a 'reflectivity' setting in the Attribute Editor .. I still get speckles?
Any ideas?

Next one is I think, (?) to get the blind casting shadows I need to use 'Directional' Light.. But I have messed about with raytacing and all settings , but got no-where until I used 'Area Light' any Ideas?

Oh yeah, I finally have an Idea! (wow.. about time !) .... This "Mad scientist guy" has made a 3D application (Maya prob)Turn the models into real life objects/beings, oh yeah and his Lab is in his 'lounge' - BUT - If I don't have time.....
He's/She's gonna invent a big Gun! - Hmm whadaya think?
