Hi can i still publish a game from unity 4.x to IOS / Android / PC ?

I am having too many issues with unity 5s wheel collider to proceed with my current project.

Yah, physx has been updated ridiculously. Some value, i believe has to be multiplied (ir divided) by 10 and wheel collider has it’s own suspension system built in.

You can publish your game, of course. It does not matter which version of unity you are using.
