View Full Version : radius of a particle?
i´ve got a simple TP setup in which particles (cubes) fall to the floor and and get reflected (they simply bounce).
but, of course, the particles bounce off from their middle, meaning the collision takes place in the middle of the cube and NOT their outer size. so the cubes fall through the floor (until the middle of theirselves) and THEN get reflected. how can i tell them to use their actual size?
i tried different settings in the TP-reflector node, but no chance.

There probably is a more "tidy" solution, but if it was me I would just fake it: Add a new floor object that is not visible in the render, move it upwards until the difference between it and the original floor matches your target radius, then use that as a collider instead of the visible floor.
yeah, i already did that, but:
1. i have different sized objects and even worse,
2. i got rotation in my objects, means i really to get the data of the actual size.
but thanks anyway.

Aaaaah.... well, that does make matters more convoluted.
Just hang around here until Srek posts a solution :D
Use the "Geometry" collision type. Make sure that all objects involved are polygon objects, parametric objects won't work.
thank you very much. But actually all the obj´s are poly-obj´s already and i also have the reflector-node settings to geometry. But anyway, i will go on trying.
Maybe i´m wrong soemwhere else.
I double checked before posting and it works. Maybe post the scene?
I think i have other settings wrong, still trying to figure out. In case i can´t cope i´ll send you the scene-file.
