BodyForce physics not being applied in WorldModel

I have a script that successfully applies a BodyForce against gravity to fling a part around in an invisible enclosed space; however when these are inside of a WorldModel that’s in a ViewPortFrame, the part’s physics aren’t rendered. Are there any other ways I could have a gui to display something such as this?

why don’t you add a normal model?

also if you are using UI then maybe the physics might not apply because it is not inside the workspace…

WorldModel is meant to allow physics interactions to work inside of a view port without having to manipulate joints/positions tediously yourself.

What are you using the viewport for?
