The cable component for me is constantly jumping or flickering when the object it is connected to is moving too fast and is too close to the camera. The objects the cable is connected to themselves are not jumping around, so the cable ends up disconnecting for split seconds. From a further distance (ie a third-person point of view), it looks fine and doesn’t have this issue.
The problem is visible in this video here as the grappling hook / rope deployed from the gun:
For those who run into this problem in the future, the solution is to set via blueprints the cable component’s tick group to post physics instead of pre.
cable still wonks out for me, turns into a lightning bolt/zig zaggy pattern
What fixed this for me is in the advanced section for the cable details remove “Use Substepping” and reduce the “Substep Time” to 0.01. Also changing the material of the cable from Opaque to Translucent will help fix the transparency issue which occurs but the material will blur unnaturally when using motion blur you will need to tick “Output depth" or “Output depth and velocity” in the material, depending on which version of UE you’re on to fix that issue.
I’m in vr so I have no motion blur. I try to avoid transparent materials as well.
Thanks!
