Here's my situation, I have a cloud plain and I have a house. Inside the
house are several lights which cast shadows. They also have fade_power and
fade_distance modifiers. Now, my render time is extremely slow because the
house is rather complex. However, I take out the clouds and the render time
is pretty fast. The reason for this change, I think, is that POV-Ray is
testing for shadows of the house on the clouds, hence doing many tests
against a complex object. Is there any way to tell POV-Ray to not test the
plane for shadows? Or is there a trick to get around this somehow?
Thanks in advance!

If you don't want the clouds to cast shadows, you can simply specify
no_shadow on the cloud object.

It's the other way around, I don't want them to recieve shadows, like the
sky_sphere does not recieve a shadow from other objects.

Lightgroups? One group that contains the house and maybe the ground if
there's light coming out of the windows. The lights in house will cast
shadows only on objects inside the group, but I don't know if it's any
faster.
