i’m trying to add a rope mesh to my scene, i’ve got bones and physic setup for a constraint but when i play the game my rope moves in all directions very fast. i’ve tried upping the mass scale but it doesn’t work. i’m stumped. please help if you can. Ive added a pic below so you can see my problem. many thanks
What settings do you use on each constraint? For starters could you try making them all completely freely constrained? If you could attach a screenshot with a constraint selected I might be able to tell you more.
What happens when you ctrl+right click and move the chains around in PhAT? does it behave correctly?
It looks like the problem here is the number of rigid bodies in the ragdoll chain.
As the chain gets longer the stability of the simulation goes down. There are two solutions to this:
The first is to reduce the number of bodies in the ragdoll.
The second is to turn on sub-stepping. This is a work in progress feature which will give the physics simulation a higher tick rate, which will stabilize the simulation.
Go to Edit>Project Settings>Physics look under the Frame Rate section and turn substepping on.
To get your particulare chain to be stable I had to set the max substep delta time to 0.008
The sub-stepping feature is not supported on mobile at this time. If you don’t mind I would like to forward this asset to NVIDIA to take a look as in this case we are really just relying on PhysX for stability and performance.
Please let me know if you have any more issues, sorry for the problems I know it’s frusterating
Thanks for your help that did the trick but it still goes crazy when the player touches it?. If i limited the number of bones everything would be ok right? yes you can send the asset to nvidia no problems.
You have to add a physics constraint actor, place the constraint actor where you want the anchor point, then look for constraint bone 1 within the physics constraint actor properties and then plug your chosen joint into it.
Hope i’m not doing your head in with all these questions :-/. i’m trying to figure out how to attach a point light to the end of the rope. I’ve set my sockets etc. but i’m having trouble fitting it all together within blueprint. Do i add the physic asset in blue print or the skeletal mesh or both? ive attached a screen shot.
