Modular Weapon Kit

If you have any suggestions or ideas for updates or future releases, share your thoughts via E-Mail / Discord

One rifle, a pile of attachments, and a customizer that actually works out of the box.

Drop the prefab in your scene, hit Play, and you get a menu on the left: swap the body colour, cycle through suppressors, magazines, grips and optics, slide the foregrip closer or further from your off hand, add rail gear to both sides at once. Six colour themes — Black, Desert, Forest, Fade, Red and Snow — and you can change the whole weapon at once or just recolour the front handguard if that's your thing.

The red dot's colour and brightness are on sliders too, so you're not stuck with the green I picked.

Adding your own models is the part I care about most. A slot is just a GameObject, and every child of it is one choice in the menu. Drag your FBX onto the slot, done — it shows up in the menu with its materials already filled in. No lists to register, no arrays to wire up. The Hierarchy window is the setup.

When you like what you built, hit Save Prefab and you get a clean, game-ready prefab: only the parts you picked, materials baked in, none of the customizer components riding along.

Everything is URP and there are no third-party dependencies. Demo scene included.
