trying to make an underground parking garage

this part of the “baseplate” union is fine, and the union uses PerciseConvexDecomposition, however:

this is- nice job roblox
the union makes me float for no reason (hollow box shape)

You’ve to change the collision to ‘PreciseConvexDecomposition’. This way it’ll shape around the parts the way you unioned it. It may cause a bit of lag if you’ve got a lot to change the collisions…

Can you download this plugin (Mesh Optimization Tools - Roblox) and send a picture of your union using the ‘‘Show Mesh Decomposition’’ plugin’s feature?
