My vertex weights arnt being applied during animation

I have part of the mesh fully weighted to a bone, but when i move that bone the vertexes dont move with it. Please help, im losing my mind here… using blender 2.82 btw

Got a file?

HI, make sure that the bone deform is checked.

I cant share the file unfortunately its a game asset :frowning:

it is checked

Sometime deleting the bones and starting again solves the problem.
You only have two bones.
Or you could delete the rest of the scene and leave the two bones,rail and the object and post it here.

ya that fixed it…
