does unioning several parts on roblox minimize the part count

by Brenden Rempel 10 min read

Do not union multiple parts - this does not stop lag. Every time studio runs the place, every individual part is loaded and unioned in the order they’re unioned in studio - it causes more lag. Instead, you should export the parts as a.obj file, and then insert them through a MeshPart.

For unioning regular parts, no, they don't reduce polygon count but increase it most times. If you aren't sure whether you should use unions or not, don't use them. There are a lot of downsides not only in terms of polygon count but loading times and unions abruptly disappearing.Mar 7, 2020
