How do I make multiple cube meshes in single blueprint one mesh

Hi,

Make one cube your root, and the others, its children. Then enable ‘simulate physics’ on the root component only. Disable ‘simulate physics’ on the children.

Regards,

I have a blueprint, and it has multiple cube meshes in it that all overlap, but when objects collide with it, they all break apart, how would I solve this by making them one mesh? (How do I make them all one mesh, or at least move with each other)
