i have set up a Chaos vehicle, it is all fine and rotation axis ,and bone axis is all pointing towards X
vehicle is moving However im having problems with collision
How can i debug the physics wheel ?
i saw there is a “pxvis collision” Command but does not work on UE5 how can i debug this ?
still cant figure out how to visually set up and see the actual Wheel collision as its way off from what is showing.
This physics are not really well documented.
just use cmd show collision
i can’t say it enough you really need to watch your rigging other wise you’ll have problems, if you need to offset in the x-axis i would guess rig issues, don’t for get to set the radius in the wheel bp, as thats what is used for physic collision and not the physics asset
as you can see on the image i have “show collision” they are OK but physically they do not match what they are doing ?
Thats the issue
Rig should be OK its pointing towards X forward event each wheel bone name is correctly pointing towards X
Even the DEMO for the Chaos vehicle is buggy…
The whole vehicle Physics systems is very bad…
thank god im not making a racing game with it, simply not possible lol
Cant event make a simple clutch as non of the option are RunTime editable its very poor…
Cant change Engine Rev at run time cant change nothing…
if its not in gear[0] it still idles Slow lol so unrealistic, cant change it
ok i mentioned that physics for the wheel uses the radius set in the wheel bp, don’t forget to make sure you use the right bone in the wheel setup, be sure your rig/skin is correct.
check your gpu , you need min rtx/gtx 2000 series.
simple answer is if Epic doesn’t need it for its games the your on your own, heard something about vehicles in Fortnight so must be do-able, and yes i have some basic vehicles working in ue5 even with my gtx960 (but not well).
do not copy that little buggy thing as that was a total bodge.
for a starting point use the sports car bp and go from there.
Atleast its possible to turn off automatic transmission and other ticks, so that you can program your own, i did that as well…
