3D models
Guitar Case yandere simulator
"Guitar Case yandere simulator" by pngslol78, licensed under CC BY 4.0.
Used for: The guitar case shown when you open a case.
Changes we made:
- Removed the character skeleton the mesh was rigged to, leaving the case on its own
- Replaced the logo on the case with the Ampin' Up mark
- Recoloured the case fabric to distinguish the Launch, Workshop and Vault cases
- Rescaled to real-world proportions and re-centred on the origin

"CSGO RMR 2020 Contenders Sticker Capsule" by MUE1337, licensed under CC BY 4.0.
Used for: The sticker capsule shown in the Shop, Storage, the Market and the Amp Pass.
Changes we made:
- Replaced the original lettering with the capsule's own name
- Recoloured the body, which now takes a per-item colour rather than a fixed one
- Decimated the mesh so four labelled variants ship for less than the single original
- Rescaled and re-centred for the in-app camera
