Question
Hello!
I am playing around with the vehiclebody nodes and I am having the issue that the wheels really want to sink into the floor.
See attached video:
Even in the lowest drop, ou can see that the back wheels are trying to go through the ground
The truck is 1500kg and gravity in the project is normal
The suspension is set to the recommended amounts in the tooltips
Thank you!
Changing the vehicle’s weight from 1500kg to 500kg has made it so it no longer falls into the floor
But that seems a bit light for a truck…
Try enabling continuous collision detection for the rigid body.
Sadly that does not seem to help
enabling continuous CD and raising the weight back to 1500kg, made the wheels sink through the floor again
What’s your ground collider? Try using a thick box or world boundary.
It is a world boundry, yeah
also tried a collision cube thats like 20m thick, which also did not work
I’d just scale the mass down by the factor of 10, if the simulation looks acceptable.
Looks like it will have to be like that, yeah
Bit of a shame though
