wheel suspension with xpresso

I've made a car rig with Xpresso and i would like to make collision for that the wheels adapt to road conditions. I know, that it's possible to make it with Xpresso but i don't know how could i do that. I want a good springing as can be done with of the wheel suspension connector.

Hi, this is something I've been looking into for a while.

For an Xpresso solution Base80 has a really good tutorial on ray collisions to stick an object to a surface, that's a pretty good start, you can just use 1 detector to get an up and down force translating into the suspension. You could also convert it easily using constraints.

I've been endlessly looking for a solution where gaps are taken into account but nothing really robust has come up.

cheers

Thannks, but i dont understand it... :(

use dynamics and connectors. You don't need Xpresso.
Download the file, press PLAY and move the top cube.

Thanks mate, but i have two problems...
-the wheels do not spin
-the car does not follow the path

How I can animate the DYNAMIC car travelling on spline or road..?

You're just trying to figure out how to make the wheels stick to a surface? If so this may help:

If you want to make a car simulation you need to either know quite good Xpresso and very good C4D dynamics, or buy a plugin that does it for you.

I have DRIVE and I can say it's amazing!!!

I would say many many many thanks to AdamT for this link.
It very useful.
How did you find it?
If you have some other link so interesting (relating wheel, spline, surfaces...) please post again.
Thanks,
Franco

Good to see you're still around Base! Base80.com is an awesome resource for sure.

I mentioned this in the 2nd post but have you ever found a way for wheels to detect gaps or bumps in a surface so the wheel and mesh don't intersect?

cheers

I know the one point detection method is a bit crude but it does the job for urban driving and soft terrain :-)
It is not a real collision system, nor a real suspension system, it just sticks a car to a probable surface.

You say it's crude, but it'd still take me a few years of my brain melting to come close

I've actually created a rig based on the 2 point collider that sort of works...
I'll try and develop it further and see if it's stable enough.

cheers
