Animated Booleans

[ptb]

Hi,

I have a scene where quite a few objects disappear slowly (get "eaten up") using animated booleans.
The problem is: Before one object starts to disappear I get the "cannot perform boolean operation" warning and since there are about 15 of them most of the time it gets slow. How can make this more efficient? Animating the node state of the boolean node is a bit problematic.
I thought about geometry caching, but this doesn't work either (cant handle 0 points).

Well first make sure all the boolenable surfaces are Cean and i mean ultra clean with no problems. You can use the nodes themselves to spot when the things should be keyed off.

But yes booleans are slow. I would suggest you use rendertime CSG if possible or raytracing boolean.
