How to make object buildable

Hey everyone! Need help
I want to take an object (bed for example) and make it huge. How can I do this so that the player can build on it?
I’ve enlarged the object, but the player can’t put buildings on it.

Hey,

The scaling must not be compatible with the building grid and attachment points.

Maybe make a BluePrint Class>Building Prop, then make a box in modelling mode, I’d go a 512x512 and 384 high.

This will keep it at building grid sizes (X/Y 512 and Z 384 increments)

Drop in the boxes and scale them as needed in whole numbers to box out inside the bed, so for example, with a leg scale it 2,2,8 and 16,12,4 for the mattress…

It may be hard to match the bed model scale to fit close to the build grid, you might have to add extra fortnite wall props to make fake legs that fit
