indoor lighting problems

Post  Scooter2 on Sun Nov 11, 2012 10:09 pm

Good evening,
I am trying to figure out indoor lighting. I have tried a lot of options and read books, but have not accomplished a reasonable quality for a kids animated movie. I have very slow internet and cant veiw movie tutorials. I have lighting for my set layer and lighting for just my character layer so I can control shadows. The problem I am having is if I use lamps for just the characters with shadows to prevent my characters mouths from being lit, I get shadows in directions that dont match the scene.
Are there any indoor lighting experts out there with advice?
Please let me know.
Thanks,
Scooter

I am by no means an expert in this area or any other in CG for that matter, but I'm going to go out on a limb and guess that you are using Cycles? I've read about it having "difficulties" with indoor scenes. I would imagine that it could be worked around to a degree by possibly cutting the indoor model in half (like a set for a tv show). Other than that there are other solutions such as Lux that seem to do better with indoor renders.

Thanks for the reply,
I am not using cycles. I did try ambiant occlusion, but what I had looked better. I will keep working on it.
Thanks,

I finally found some information about faking shadows using negative lights. I place a spot light inside the characters mout pointing down at the toung set to sphere falloff with a square shape and shadow set. Placement location is sensitive and requires some experimentation. I got this to work the way I want for now.
Good luck.
