What is best way to reduce lag?

Im creating experience with thousands of parts.
How could i remove lag from that experience?

I can’t use Blender now so im making my assets in Studio.

Someone said you should union every roblox part. I tried it but it didn’t help.

Do you have any other tips to reduce lag?

Exactly what @RobloxKonnie said. Trust me, when I first used studio, I hadn’t realized the actual scope of Roblox’s capabilities when it comes to its engine, so you may have to reduce your part count or create a chunk system. Good luck : )

Try using StreamingEnabled, this could potentially help your game work better.

Thanks! I’ll try it.

That map is over 3k studs long

Ah don’t worry about that, I used StreamingEnabled on a map that’s 26K studs and a total of:
image it works perfectly fine.

This actually has the opposite effect most of the time. Don’t do this.

Check out my RDC 2020 talk about making maps more performance-friendly


If you have a lot of parts, instead of using Unions (which don’t affect performance) instead use meshes. a good explanation and tutorial on converting parts to meshes can be found here: Studio Tips Guide #1 - Converting Models to Meshes though I also recommend enabling StreamingEnabled, it only loads BaseParts that are within a range of the player (i don’t exactly know how it works, but I do know it can help for games with bigger maps/more parts).

Edit: i just realized someone already suggested StreamingEnabled but ima keep it in this reply anyways.
