How many number of faces in a model make it too laggy for mobile players?

How many faces are acceptable and easily handled by an average mobile players devices? I really wonder because i have some models with 19k ish faces and i want to make the game mobile compatible too…

Roblox won’t let you insert a mesh that exceeds 10,000 triangles, so I’m assuming any mesh Roblox allows you to import, should run smoothly on all devices. Of course, if you are moving/modifying multiple meshes with triangles that add up to over 10,000, you’ll begin to see some lag.

It honestly depends. If you plan on making this game build heavy (not a lot of scripts, basic lighting, etc.) then you can probably go upwards of 75-100k faces, but any way that you can reduce that number is ideal. However, if you plan on using a fair amount of code and make the game generally more realistic, you’re gonna need to reduce the vert numbers.

P.S. I’d recommend decimating those models with 19k faces, that’s a LOT for a single model, regardless of what it is.

What is your Mesh, a car, an avatar, a mountain?
As @AlbertSeir and @Advareo said, the more tris (faces) you have, the more lag you will cause when rendering them.

Maybe have a look at other Meshes in the library that are similar to yours and compare how many tris yours has compared to those.
