Hi, yes I saw that vid. If you want to be able to tweak that color parameter and see the changes in realtime, then take that blueprint code you have and put it in the construction script ( next tab along the top ).
I’m sure you’ve noticed you can actually connect the GetSocketLocation into the color param. That’s only because they are both 3 numbers. Connecting them wont help I’m afraid.
Having talked about manipulating colors this whole time, I don’t think it’s where we need to be. The animations you have in Maya can be played in UE and you can manipulate the skeleton, but you have to set it up as in the vid I sent before ( Custom Animations from Maya to UE4 [TUTORIAL] - YouTube ). That shows you how to make the bones work in UE.
Sorry to not be much help.
