Phat based collision affecting class instead of only instance

My set up is one blueprint with a skeletal mesh, this mesh can be a chain or a rope, I decide this in the construction script, I assign the corresponding Phat here too.

There is some weird behaviour that happens if I collide with an instance of my blueprint it is affecting the other instances, this is clearer to see in the video.

My problem is that when I collide with the chain the rope has some of its collision removed, if I don´t touch the chain first I can grab the rope from the last bone.

this edit is just a shameless bump, only someone from epic can help me with this(I think)

I am working exclusively in blueprints, so I have no access to the code to know what is going on and if I should change the skeletal mesh and phat of a blueprint on class instantiation.

I beg for your help, this is so specific that I don´t even know what to google to find some answer.

I’ve tried on my end to replicate this using a physics like chain with multiple PHAT hulls.

I’ve added the chain to a BP and placed multiple instances. When I collide with one it doesn’t affect how the others collision reacts or the inability to collide.

Looking at your video I can see that you’ve mentioned it’s not grabbing on due to collision, but since you don’t have a view enabled that shows the collision of the mesh (Console Command > Show Collision) it makes it more difficult to see where the collision is for the mesh. If you make another video with this demonstrated please do so with a single player window. It will be easier to see as well.

Also if you have an example that can be setup outside of your project or one that you could provide I could replicate more easily on my end and test or debug what’s going on in your example.

Let me know.

Tim thanks for your attention, I am very sorry to admit that I cannot replicate my problem either, I had moved on, created a blueprint for a chain and one for a rope, I tried to recreate the older setup and now it works as it should.

Without test cases this question should be closed.

If you end up getting a reproducible result please let me know and we can take it from there.

Thank you!
