Collsion in Particle System and Matinee

Imatk

So I've got some sparks colliding on the ground and it works perfectly, but when I make a cut-scene movie in matinee, the sparks do not collide until the camera gets very close to them.

Anyone know why this might be happening?

Thanks for any help!

Ahh I just found it... had to increase my max distance for collision sorry
