How to people deal with pass-through?

[djembeplay]

Well, I seem to be full of questions. As long as I'm here I figured I would throw this one out there.

How do you guys deal with objects passing through eachother?

I mean, I know that you can work some espresso magic to prevent pass-through in the editor window... but do you guys (or professional animators in general) use this for every object? Or do you generally just pay attention to your objects and edit them so they will not pass through eachother?

Hey Dj. If your coming from game programming your first instinct would be to have collision detection on everything that moves. Game engines have greatly optimized code for high speed detection whereas 3D is pretty slow at it.

Generaly in 3D you animate your characters and objects to avoid other objects and walls, ect. The exception is if you expect something like, say, particles, broken glass, a bouncing ball to interact with the enviroment or another object/s, then you would assign dynamics to the objects invloved and not to the ones not invloved. Another exception might be if you have crowds where the people need to avoid each other, then you would assign some code so they can avoid each other.

But no, you generally dont use it unless you have to.
