I have three geometries, two point geometries emit particles in a line, like a laser beam, and the third is a plane.
I could set the third, the mirror, to collide with the two particle streams. Now, I want to have that one of the two particles emitted from one of the two surfaces does not collide while the other particle stream does collide.
Can I set the collision on the mirror dependent on the particle emitter?
I have attached my attempt, which is difficult to see. What you see there are a blue beam a green beam and a red beam colinear on a semi transparent mirror. Here, I want to make the mirror reflecting only the red particle stream and passing though the both others.
