I really want to make Elongation and Colossus from Halo 2 but I’m not doing either until I get working conveyor belts. I can get the belt scripted to move very smoothly. The problem lies with the belt actually moving the player and objects. If their anything I can do without adding feet grabbing object to get the moving block to move players and objects?
You could define an area monitor for the length of the belt.
Then using on “Every n Seconds” - get value of any objects inside the zone and move them.
Probably going to need some clever vector maths to make sure you are moving parallel with the conveyer belt though. And probably won’t play fair with players running against the direction of the belt and/or jumping.
I’ve added volumes with velocity to my Forge suggestion post. 
I started playing with this concept of “Every n seconds move objects in the area monitor”. My first pass was very jittery and I hope to clean it up with timings and other checks. I’ll ask a stupid question b/c I was struggling with it. Is there a way to have physics phased during the building in order to mash up an object of multiple objects and then apply normal physics to the group during gameplay?
I’m pretty sure once you switch from phased yo normal you’ll always get item shift.
