Real world building and scripting optimization for Roblox

Started to wonder one thing about “baking” models.
What other data does Union store other than it’s CSG data and how can it affect performance? (despite its mesh having no changes compared to meshpart one)
(ive also seen in RDC they’re on a lower tier than parts so i’ve started to wonder about that part)

Hello, when you say do no batch, what does that mean?

“Batching” as in instancing process (rendering multiple objects with 1 drawcall). It’s just how I name it.
