Rendering but it's a black screen

[Anonymous]

I'm trying to render my house, but each time I do it's the house is a silhouette or black screen. If anyone knows the solution to this I'd appreciate it.

You don't have any lights outside. I put one outside and turned it way up and you can see it lights the exterior.

I noticed a few other things. The material you have for the glass in the windows is an opaque material. It's not transparent. Some of the polygons that have glass in slot '1' of the multimaterial are not Material ID 1. So the glass isn't getting applied to them. Some of the lights inside the house are within opaque objects so not light can get out. Lastly, the lights need to have the multiplier set to about 10,000 to cast enough light to see the illumination.

Can you give more info, show screenshots, type of lighting, mention render engine and version of Max, etc.? It's difficult to know without some details.
