Nice one Rampa! - I always enjoy your tutorials .... (for some reason though it cut off a tad short (for me anyway) at 29:00 - don't know why).
But yeah - great practical advice with a result that yields "great mileage"!!! - thanks for sharing - I'll be adding this to my "favorites" list) ....  :)
Steve.

Please be patient with me ..... I don't always 'get it' the first time 'round - not even the 2nd time! :(  - yikes! ...

Thanx a lot! Easy to follow tutorial.
I got the chasis so far...




But i behaves way "bumpier" as yours. Set Spring Limit Range to 5 instead of 25, did not change anything...



AND when attaching the car something went wrong:



I will redo that process (unfortunately this part is missing in your tutorial)

Still got problems with the springs, but overall a nice, very nice tool :w00t:
Will, (after i got those springs working :pinch:) defintely make my car scenes better.
Especially for "drifting" scenes ;)

Glad to see it's working! :)

Remember how I pretty much left the physics at defaults? Now that it's built and tested, it is a good time to start wrenching on your car. ;)

To get a smoother wheel roll, try adjusting the physics damping of the wheels themselves (not the hinges) up a bit. This is somewhat terrain dependent as well. You can quickly select all the wheels at once in the scene manager.


Another thing you can do if you run into an issue of your wheels hitting the cross bars, is make the cross bars shorter, but keep the hings in the same location. There should be no interaction between the child and parent pieces, but I think it will between the wheels and four-bar struts.


Sometimes it helps to select all the car bits and lower them slightly into the terrain. This will insure good wheel-to-ground adhesion.

The last word of the video is "terrain". :)

Hello, Rampa,
Very good tutorial, thank you very much,
I'll try it soon.
Greeting rosuckmedia :)

Tried several things, but it did not really help.
Lowering the car helped a bit.
But moving in terrain was quite a desaster :D
I will try to do the whole thing from scratch.

Another test...



I really love the "Drifting" effect and the "Shaking" of the car at the end.
But wheels simply don't behave as i would like they do.
Using the spheres (bounding) for wheels work in most cases better than convex hull.
At least they don't make the car bump that heavy, in other, (sharp turn) it's very bad...
Using "Self Mesh" makes iClone crash.
What was really strange, as i tried adding cameras to get the angles that work,
to mask the ugly wheel behaviour, the car went mayhem.
And at a critical point, it kept going mayhem.
Only starting from the point with only one cam (saved as a project) worked.
Also in render i had different behaviour.
Rendered twice and the car did not got that nice shaky end.
So i captured it from screen...
So, many cool things in your tool, needs more tweaking somehow.

The blocks that the springs attach to are also moving all the time, so try damping them as well. There are so many variable, that you just need to keep tweaking different things.
