particle trouble

[dblanky]

I've come across a problem thats really bugging me! It's a simple scene with a glass in it and a particle emitter above it (the tap) i put collison on the glass and set them both to a group but when the particles fall down they go straight through the glass, that or they stop in the middle of it, nowhere near the actual object! how can i sort this problem out?

Thanks for any help

Sounds like you have your radius/level set too high in the collision panel.

i tried ti adjust the radius/level to the least value where no partcicles will pass through anymore and i got BUT there is a gap already between the surface of the object where the particles are to hit and the particles themeslves. it's like there's an invisible force field or something... is there any other way for this?
