Maybe my setup is way to overcomplicated, so what do you guys suggest on how to build a scene like this:
A logo, consisting of two letters, the M and the W. I want two emitters above the letters to emit particles (spheres) that fall into the letters (which are invisable) to form the logo. On a given frame i want to disable the deflector, and let the spheres fall onto the groundplane.
The way i build my scene:
I made my logo editable polly, removed the top face of the M and the three top faces of the W, add a shell modifier, and a Physx Collision Shape. I have a couple of invisable tubes (with Physx Collision Shape) to guide the sphere's into the open letters. This setup works, the letters fill up with sphere's.
But how to 'disable' the Physx Collision Shape. I know you can't just disable it, but isnt there a workaround??? I tried to chop my letters into a front and backside, which i animated out of the scene between two frames time (Animated Geometry enabled). This doesnt work, the spheres keep in place. PsychoSilence add a melt modifier to the letters, but this smashed the sphere's to the ground instead of falling do to gravity.
I hope you guys have some advice, because i've watched a lot of tutorials, but didnt find anything usefull for my problem.
