hey all, well i would like to know if this (question) is possible, cuz i want to make caterpillar wheels of this machine works. but i want to drag actors by physical materials or something like that. Please, could you helpme with this? 
there is something that i can do?
i tried this, it works! but i think this is very annoying for configure it: i’ve used static meshes that are rotating constantly and the hidden when i play the game.
there is another way? ty!
You could create a trigger volume and when an object is inside that trigger volume add the desired movement to it through blueprint. This would be a lot easier on your frame rate as well. Let me know if that isn’t clear enough and I will make a mock-up.
i ll try it. 
ehmmm… Could you illustrate me your suggestion?
Sure, check this out. The first image is the TriggerBox I created to detect overlapping actors.

Now you are going to want to apply movement to all overlapping actors. I wanted to apply movement in the Y direction. You can change this with a variable though as that will probably suit you a lot better.

So for your needs you would place this box just above the surface of your conveyor belt, with dimensions that fit the size of your conveyor and everything should be just peachy.
