Cyberpunk Prosthetic Arm: is this $12.99 stack worth it for 3D?
If your VRChat avatar is starting to feel a bit too “standard” and you want that specific, high-contrast retro-futurist look without spending weeks learning how to rig a cybernetic limb from scratch, this is the shortcut. Cyberpunk Prosthetic Arm (Blender, VRChat) is a $12.99 package that hands you a fully rigged, skinned arm ready for immediate attachment. It’s not just a mesh file; it’s a complete workflow stack that includes the source Blender project, the Substance Painter textures for customization, and a Unity package with pre-configured materials. If you’ve been eyeing that “mecha” aesthetic for your character but got stuck on the technical rigging or shader setup, this bundle bridges the gap between a cool concept and a working asset in your scene.

What you’re actually buying
At $12.99, you aren’t just buying a 3D model; you are buying the entire pipeline to get that model onto your avatar. The core deliverable is a pre-set up Blender project (version 4.2) containing the arm, which is modeled with 12.5k triangles, 18 bones, and a skinned mesh. This is the part that saves you the most time: the rigging is already done, so you don’t need to wrestle with bone weights or skinning issues. (Cyberpunk Prosthetic Arm (Blender, VRChat))
But the value really spikes with the inclusion of the Substance Painter project (version 9.0.0). This means if you want to tweak the wear, tear, or color scheme of the metal plating, you have the source file to do so. You don’t have to settle for the default texture if you want a specific patina or glow. Additionally, you get a Unity package with materials already set up using the Poiyomi Toon shader, which is a standard for VRChat avatars. This ensures that when you import the arm into your Unity project, the lighting and toon-shading look correct out of the box. (Cyberpunk Prosthetic Arm (Blender, VRChat))
To make sure you don’t get stuck, the package includes an illustrated step-by-step tutorial for attaching the arm. One buyer noted that the “instructions were super simple to follow,” which is a huge relief for anyone who has ever stared at a Blender interface wondering where the bone hierarchy goes. If you are comfortable with the basics of opening a project and following a guide, this stack is designed to get you from purchase to “arm attached” in a single sitting.

Why it’s on our radar
This asset is interesting because it solves a very specific niche problem: the “cool factor” of a cyberpunk limb often comes with a high technical barrier. Most free or cheap assets are just meshes with no rigging, forcing the user to do the hard 80% of the work. By including the Substance Painter project and the Unity material package alongside the rigged Blender file, this offer removes the friction of shader setup and texture customization. It’s a rare find at this price point to get the source of the textures, not just the final image. (Cyberpunk Prosthetic Arm (Blender, VRChat))
The seller also offers an Installation service if you are “scared of Blender,” which is a thoughtful addition for buyers who want the aesthetic but not the technical headache. The fact that one buyer mentioned they had been “waiting for release for SO FUCKING LONG” suggests this is a highly anticipated style in the VRChat community, and the fact that it ships with such a complete file set makes it a strong value pick for anyone looking to upgrade their avatar’s look without commissioning a full custom build.

What actually matters
Before you click buy, there are a few technical details you need to verify against your current setup: (Cyberpunk Prosthetic Arm (Blender, VRChat))
- Blender Knowledge: The listing explicitly states that this asset requires basic Blender knowledge to be installed. If you have never opened Blender before, you will need to learn the basics of parenting and bone attachment. The tutorial helps, but it doesn’t replace the software learning curve. (Cyberpunk Prosthetic Arm (Blender, VRChat))
- Avatar Proportions: The arm was modeled with Rexouium avatar proportions as the reference. If your avatar base is significantly different in scale or limb length, you may need to do some scaling or editing in Blender to make it fit naturally. (Cyberpunk Prosthetic Arm (Blender, VRChat))
- Clothing Compatibility: Any clothing that goes over the arms will be incompatible with this asset. If your avatar has long sleeves or gloves that cover the forearm, you will need to edit those clothing items to accommodate the new arm geometry. (Cyberpunk Prosthetic Arm (Blender, VRChat))
- Shader Dependency: The materials use the Poiyomi Toon shader. If your Unity project doesn’t already use this shader, you will need to install it (it’s free) to ensure the arm renders correctly. (Cyberpunk Prosthetic Arm (Blender, VRChat))
Mid-check
If you have the Blender basics down and your avatar base is standard, this is a low-risk, high-reward upgrade. (Cyberpunk Prosthetic Arm (Blender, VRChat))
FAQ
Do I need to know how to use Substance Painter to buy this? No, you only need it if you want to modify the textures. The Unity package includes pre-set materials, so you can skip Substance Painter entirely and just use the textures as they are. The Substance Painter project is a bonus for customization. (Cyberpunk Prosthetic Arm (Blender, VRChat))
Will this arm work with my existing VRChat avatar? It should, provided your avatar uses standard proportions. The arm is rigged with 18 bones, so it will animate with your existing arm bones. However, if your avatar has a unique scale or custom bone structure, you may need to adjust the arm in Blender before importing it to Unity. (Cyberpunk Prosthetic Arm (Blender, VRChat))
Is there a service to install it for me? Yes, the seller offers an Installation service for an additional cost. This is a great option if you want the arm but don’t want to touch Blender. You can check the current availability and pricing on the product page.
Bottom line
For $12.99, getting a fully rigged, skinned, and textured cyberpunk arm with all source files is a solid deal. It saves you the hours of rigging and the guesswork of shader setup. If you want to add that “robotics department” vibe to your avatar and you’re comfortable following a tutorial in Blender, this is the way to do it. (Cyberpunk Prosthetic Arm (Blender, VRChat))
