Hi,
I’m experimenting with moving a round object along various curved surfaces (circles and bends, etc). I’m using the method of raycasting to get the surface normal and then inverting it and using that as either a downward force or setting gravity in that direction (after normalizing/multiplying the vector). Both work ok but since I’m using polygons, the round object kind of bumps along the surface (see picture).
Using gravity I got smoother results but I was wondering if there were any other solutions apart from maybe a smoother collision mesh?
Here’s some pictures using the trail renderer to show the bumps.

Hi, yes that possible (and I’ll try that for the completely round platforms) but some platforms are L shaped (like a pipe curving upwards) so their centre will be in an odd place. So that won’t work for that.
Yup, I’m using a sphere collider but even that is not perfectly round (at least it’s not visibly perfectly round in Unity). I zoomed in to see why the bumps were happening and the sphere actually goes though the surface of the ‘planet’ just a little bit after each face. I’ve fiddled with the physics properties but nothing makes it any better. I guess what happens is that after each peak (the angle difference between each face) the sphere realigns, via the normals calculation and then pushes back into the ‘planet’. Maybe if I play around with the strength of gravity it won’t be so obvious. The Sphere (moving object) is 1m size btw, if it makes any difference.
