In Roblox Rivals , you usually cannot change the game’s built-in cursor shape directly unless the game itself includes a cursor or crosshair setting. What players usually mean by “custom cursor” is either a crosshair setting inside Rivals or a client-side Roblox cursor swap used in Roblox generally.

What Rivals supports

Rivals appears to have an in-game crosshair customization menu, with options like static crosshair, scale, spacing, and side bars. That affects your aiming reticle, not necessarily the system mouse cursor.

Common ways people do it

  • In-game crosshair settings: Use the gear/settings menu in Rivals and adjust the crosshair there.
  • Roblox cursor replacement: Some tutorials show replacing Roblox cursor files on your device with custom PNGs, but that is a local modification and may stop working after updates.
  • For your own Roblox game: In Roblox Studio, you can set Mouse.Icon to a custom image asset in a LocalScript.

Safer option

If your goal is just a different look while playing Rivals, the safest route is the built-in crosshair editor inside the game. If your goal is to make a custom cursor for a game you are building, use Mouse.Icon in Roblox Studio instead.

Simple example

For your own Roblox experience, a LocalScript can point the mouse to an uploaded image asset like this: Mouse.Icon = "rbxassetid://YOUR_IMAGE_ID".

TL;DR: Rivals usually lets you customize the crosshair , not fully swap the cursor shape, unless you use broader Roblox cursor tweaks on your own device.
