car is flying when i link the ground to gravitydirection?

[patfish]

Hi guys!
I use 3DS Max and the hole car-rig works fine when i don't link my ground plan to the "gravitydirection"-helper.
But when i link my ground plane to the "gravitydirection"-helper my car jumps up a bit and starts to fly slowly without touching my keyboard.
My ground is an simple flat plane which is rotate by ~3° to match my 3D tracked camera in the scene.
Any idea to bring my car on the ground plan?

thx for all patfish

Patfish,

Are you using the latest version (v9.3.1)? If not, download and install it and the problem should be fixed:

Hi Carl!
yes, i do already use the new version. I fixed the problem now by de-selecting the "use fast ray cast" function and decrease the "Ray Multiplier" to 1. Also i figured out that it makes a difference if you link the street to the "gravity direction" helper or reverse. in one case (i already forgot which was the right link direction *g*) the car flies 1m above the street. In the other case it works fine.

thx pat

The GravityDirectionMesh should always be linked to the ground.
