Is it just me, or does Carrara suddenly take a loooooong time to render when you have Sky Lighting or Indirect Lighting on, and there's hair or some other transmapped material in the scene? Of course it's not me! Why is that?! (arghhh!)

I've been trying to find ways to get around this, but so far nothing really seems to help. Reducing the size of the texture files doesn't help. Reducing the quality of the lighting effects helps, but only barely. The only way I've been able to get around it up to this point is by not using Sky Lighting at all, and just mocking up a pseudo light dome with Distant lights... which is really just cheating!

So, was just wondering, are there any good tricks for getting around this? Is there some way to turn off render settings for certain objects?
