Need Help with procedural meshes

Hi!

Like the title says, I need help with procedural meshes. this is for the crafting mechanism in my game.

By crafting I mean you actually take a mesh from the game and separate, bend or demolish pieces of it. and add those to other meshes. I never really saw this in games, but I know it is possible in some way. I only do not know how.

Does anyone knows the progress of modifying & adding meshes via script real time?

Thanks in advance,

Teunu
