Object bind to surface jitter - Booclay - 10-27-2024
Hi,
I've always had this problem with the object bind, when combined with motion. Essentially it looks like the particles don't travel along the surface consistently. Some particles seem to be moving really slowly, some erratically jump position, some just seem to noddle off on a really small part of the mesh and don't move at all.
here is an example scene (2024) and an mp4 of whats happening:

In this example, in the lower left, particles are jumping around. But all over there is inconsistent speed and odd movement.
If I put splines on the particles as trails, you can see it even worse. The lines are all jagged.
Is there anyway I can get the motion consistent, speed, acceleration, etc?
Increasing the step time from frame to 1/8th seems to help but is there anything else?
Many thanks

In Object Bind operator, try changing sample from "face hybrid" to just "face".
That way, the operator will look at your mesh as it is, and not simplified version.
Also, you can try and add turbosmooth to your mesh (so operator have more polygons to work with), and some Ty Relax (so you make smoother all the sharp angle areas).
I tried it... it seems like it's smoother now.

Ace, thank you. great info. I'll give it a go now.
