(VRChat) M203 Underbarrel

IMPORTANT: The installation process is different than everything else on my store. Pay close attention to the video and be sure to check the Time Stamps to ensure you know what you are doing. Or read the instructions below and/or in the prefab folders.

Expect some latency, so the Grenade may not be in the exact place. This is due to culling. This may occur more often because the Grenade has gravity.

The M203 has an Ammo System that fires 1 Round before you need to reload.

A Chance of ricocheting the Grenade, depending on the angle.

The main feature is that the Grenade Launcher will explode on impact or on its own after 1.5 seconds.

A Screenspace effect when shot by the Grenade. A Red Ring around the Corner of the Screen.
