Can splines avoid intersection while following a surface? - Narad13 - 03-28-2024
Hello? I have an ivy growth animation that I'm working on and I want the parent particles (and splines) to avoid intersection while tracing the surface of a model. i'm currently using Surface Force and Object Bind. is it possible to allow some wiggle room to allow particles to go over and under each other when crossing? Or is there a better way to set this up entirely? thanks in advance

To get splines to collide you can try a couple of options:
1) Use Particle Physics...but the splines need to be of a dense-enough resolution so that their constituent particles will collide.
2) Use Particle Bind...bind by siblings or whatever works for your setup, then enable CCCS collisions for them (requires BETA or PRO).

Thanks I'll give these two things a shot

Hi Tyson,
your suggestion seems like a cool workaround, but how do i use particle physics with splines meaning how to test the polys of the meshed splines? I tried using an edit poly modifier on top of the spline mesher as a birth object for using the particle physics, but no luck. Tried using the mesh operator unticked the point "at rendertime", tried tyMesher with epoly on top - all describedin many variants, but still no luck...
Attached you can find my test setup ...
Can you give me a hint please?
Thank you

Please, I'm stuck with that - is there a solution outhere?
