Hi there. Are there any tools around that will take the wheels of a Blender model (probably called Wheel1 etc) and create the colliders ready to be used in the editor? Or can this only be done manually? Thanks.
As specified in my post in the other thread, this is something that you can code. https://forum.unity.com/threads/multiple-models-with-colliders.898400/ An existing asset that does it might exist, but given that difficulty of programming things is fairly low, I'm not sure I'd want to bother with buying an asset.
So, I bought NWH Vehicle Physics asset for this reason, and as @neginfinity said, it's actually easy to roll one out on your own, and I ended up doing that, because it was more lightweight, and tailored to my own needs. I don't regret buying NWH Vehicle Physics though, as it provides a real example of the results that I wanted, and I used that to examine how I should implement my own solution. The major work that I needed to do to get this working is re-orient all my vehicle models to face +Y, as I originally had them on the +X. This is needed because the Unity WheelCollider requires it. Otherwise you end up with vehicles moving sideways.
