how to keep point lights from adding to eachother…
AARGH! The way After Effects computes several point lights in a scene is very strange to me… Here’s the problem: In one comp i have nested an indoor scene and an outdoor scene. The indoor scene needs a warm fireplace light and the outdoor scene needs a cool blue moonlight. But setting a nice yellow point light inside my “house” (yes, i have even made walls, floor and roof to try and fix this) and a blue point light on the outside causes the inside scene to be washed out white as if i hade set the inside lights intensity to 200 percent or more… After effects seems to ignore that the “house” has walls blocking of the outside light…
The only workaround i have found yet is to use spotlights. BUT I DON WANNA! Am considering trying out Trapcode Lux and thereby bypassing After effects way of computing “interfering” lights. Any other workarounds???
Also, why cant i use lights in a precomp (continuus raster, of course)? All lights in the precomp are ignored in the final comp, what gives??
Thanks for help

you may need to set your house’s walls to “cast shadows”…

Thanks peder, will check. So now i did a test comp putting one solid in front of the other and moving a light. The light ignores the fact that it is being blocked by a solid!! Is this always true in AE???

that’s what I’m saying: you need to activate the “cast shadows” property on the layers that shall cast shadows. also, the light has a “cast shadows” property I think.

Yea i get you, tried it, but it still seems that AE ignores the fact that a solid is blocking the light: if i make a cube of solids, and put the light inside it, objects outside the cube which logically should have no illumination are illuminated as if the walls enclosing the light werent there…
Casting shadows helps to some degree but only if the shadow falls directly onto the outside layer.
Guess i’ll have to finally admit that not everything can be done in AE 🙁

yeah, well, it’s not ray-tracing so it’s not that exact. nevertheless I feel that the inside/outside thing should work. there are also settings for shadow darkness (can’t remember the exact name) maybe that could help…
