a while ago in UDK i made this off road buggy
it worked pretty well but had a couple of issues, 1: the driveshafts didnt move, 2: if you look at where the wheels attach to the suspension as it moved up and down there was a slight gap because the wheels only moved straight up and down (just like UE4) but the suspension moved in an arc. I made a test vehicle to see if i could correct these issues in UE4, so basically make the wheels move in an arc with the suspension and get the driveshafts spinning with the wheels and it seems doable, heres a quick vid of my test.
as you can see it did work (i know the model sucks:p), even though it looks like the driveshaft and wheel are being controled by the same bone they actually have the own bones, the wheel is using the driveshafts bone to rotate around and the driveshaft is getting its rotation from the wheel, I am going to try and merge it all into 1 vehicle in UE4 to create a true fully functional vehicle but with this new mesh (Buggy MK2:)).
obviously I am still modelling it (I made it fully smooth just to show roughly what it would look like). if i manage to get the new car working I’m planning to release it as a template/example for people to take apart and play around with.
I was just wondering if anyone would be interested in this template/example or not?
