non-rotating front-wheel parts (e.g. brakes)

[krz9000]

hi craft,

i finally found time to use the trial to play around with your plugin. i can imagine getting yxour tool for car animation but one thing seems to be missing? (very likely im just too uninformed about all the features):

a cars front wheel typically has rotating and non-rotating parts:
- the tyre, the rims and the breakdisc are rotation with forward-movement
- the breaks do not rotate with forward-movement

but all these parts rotate with steering.

sofar i didnt found a way to parent the brakes in a way that they only rotate with steering but not with forward-movement.

i hope u can give me a hint how to do it, or if this feature is not there how to make a workaround. im on maya and i guess i can just link some values together. nevertheless to have a "non-rotating" group in the rig-hierarchy would make things easier.

thanks in advance
krz

Hi krz9000 and welcome to the forum!

There is a solution for your problem.
Parent your brake setup to one the following nodes:
WheelerExt_01_WheelCenterMesh_FRTransform
WheelerExt_01_WheelCenterMesh_FLTransform
WheelerExt_01_WheelCenterMesh_BLTransform
WheelerExt_01_WheelCenterMesh_BRTransform

These nodes you can find in the top center of the 4-Wheelers wheels.

Hope you find them, Good luck!

if i put the breaks there - they will not rotate with steering. at least not with the version i have. i try to download again maybe i have not the latest version

If you go in to the configure for the 4-Wheeler and go down to the Suspension Parameters you should find a check box that is named Fixate Wheel Center Nodes uncheck this box and then it should work.

WIth this method, were the brakes grouped in the wheel group? I am just starting learning today, and see that you have to have 5 groups (4 wheels and the chasis). Thanks.

Well you parent the brake(the red part) to the WheelCenterMesh and the brakedisk you group with the model wheel and link/parent this to the WheelMesh of the 4-Wheeler.

OK, thanks I understand now.

You would do the same thing as the answer above. The Craft 2-Wheeler Extended also have a WheelCenterMesh in the front wheel and one in the rear wheel. If you are animating a bicycle you would also change the Maximum Pitch Angle to 0.
