Hi everyone,

I am making a shuttle crash and when shuttle contact the ground, particles emit from the ground. It's working well but with one problem: they are appearing on the wrong side of the ground. You can see the example scene as attachment. How do you think I can correct this?

Thanks and cheers.

change the direction in the particle emitters attributes... or rotate the emitter

Thanks dan1el,

Well particles emit by the result of an expression. Every time a connection is made between two rigid bodies, particles emit. So there is no emitter but the rigid body. Is there a way for a situation like that too?

Cheers.

Try to reverse the normals of the ground.

I've never used that type of "Collision Emission" cuz I've always heard that it is very slow. If I'm to make a wild guess here (if inverting the normals from ground as sugested didn't work): I guess you have an expression testing if object A collides with object B... try to invert the test, making it "if object B collides with object A".

If you want to try something else then expressions with rigid bodies:

I've used it before and works like a charm.
