How to create an extra wheel for a truck?
-------------------------------------------------
Hi to all!
I am beginner user of Craft Animation DirectorStudio.
I use 3DSMax 2010 x64Bit+SP1.
I have made a successfull rigging with 4WheelerExt Craft Tools of a truck with a trailer that have the two first wheels that follow the tractor.

- But how to create the others two fixed extra wheels of the trailer that follow it?

See the attached image.

I tried with two Extra Wheel Tool, but unsuccessfully, these wheels, steering also when the tractor steering!
- How to create them fixed, without the steering?
- What tool I need?

Many thanks!
Horsepower.

Hi Horsepower,

Check the configuration dialog for ExtraWheel. There you will find a checkbox named "fixate"-something. Check it and the wheel will not turn anymore.

OK!
Thanks you!
Now the wheels run correctly (if I don't link the GravityDirectionMesh to any ground)!
Thus the default invisible zero ground is used and the simulation is correct.

- But I tried to link the GravityDirectionMesh red arrows for the 4Wheeler,for the Trailer and for the ExtraWheels, directly to the editable mesh of the ground (one surface only with multiple parts attached as EditableMesh).
The simulation have errors!
The truck lift from the ground and doesn't respect the level of the polygonal geometry.
Please help!
I attached the URL of my "3DSMax 2010x64Bit+ServicePack1" + "CraftDirectorStudio" scene file:

In brief: I have made a polygonal ramp. I want that the truck run over it and after that go over the flat ground.
- Please can anyone test my scene geometry?
- It's all right for the simulation?
Thanks!

Horsepower.

Hi Horsepower,

I tested out your scene and indeed it is not working as it should. What I can see though is that it is attaching to some kind of ground and that it thinks that there is some "ghost"-ground that represents the mesh you have with the ramp.

I did create a new mesh and that worked just fine. I don't know what you did to the mesh that's in the scene but my suggestion is that you recreate the ground again and see if that works for you and if you are using the attach function when editing a mesh that should work just fine two.

Are you able to describe in more detail how you created the ground?
