Ghostly [ Mama-Gen ]: A VRChat avatar base with source files, dynamic bones, and tiered features
Building a VRChat avatar from scratch is a massive time sink. You need to model, rig, texture, set up shaders, and then wrestle with the Avatar 3.0 menu system just to get basic tracking working. For many creators, that process takes weeks of trial and error.
Ghostly [ Mama-Gen ] cuts that timeline dramatically. It’s a pre-rigged, high-tech armored avatar base that comes with full source files, meaning you can customize the look without starting from a blank .blend file. If you’re looking for a “motherly beast” aesthetic with dynamic bone jiggle, energy blade SFX, and a functional Quest variant, this is a specific tool for a specific job.
At $40, you’re paying for the shortcut and the technical setup. Here’s exactly what lands in your folder and whether the tiered structure matches your project.

What you’re actually buying
Ghostly [ Mama-Gen ] is not just a finished model; it’s a development kit. The core value proposition is that it includes the Blender/FBX source files, PSD textures, and Substance Painter files. This means you aren’t locked into the default look. You can re-skin the armor, adjust the RGB emission levels, and modify the geometry to fit your specific character design. For $40, getting the full source chain is a significant advantage over buying a locked, single-file avatar.
The technical setup is already handled. The package comes with a prepared Unity scene that is compatible with VRC SDK Avatar 3.0 and Poiyomi Shader. It includes full-body tracking support with advanced Avatar 3.0 menus, so you don’t have to figure out the slider logic yourself. The rig features dynamic bone jiggle on the “tum chub” assets, and the armor is equipped with toggleable energy blades that include sound effects. You can also dematerialize the visor on and off, a small detail that adds interactivity to your avatar’s performance.
The $40 price point unlocks three tiers of functionality, and the differences are substantial. Tier 1 gives you the base version with the prepared Unity scene, full-body tracking, and the aforementioned SFX and visual toggles. Tier 2 adds the full-feature base and dedicated 3.0 Avatar menus for sliders, giving you more control over the model’s parameters. Tier 3 is the most unique offering: it includes a fully functional Milk-Pump unit integrated into the armor, with toggleable pumping actions, milk particle effects, and a maternity slider for belly growth.
It’s also ready for mobile. The package includes a Quest variant set up with the Android SDK in Unity. This is rare for high-spec avatars, as most creators assume you’re only targeting desktop. If you need your avatar to run on Quest 2/3 with optimized performance, this pre-configured variant saves you from having to optimize the model yourself.
Before you buy, confirm you have the required dependencies. The listing explicitly requires VRCFury SPS (Tier 2+) and the JerryFaceTracking Template for facetracking. If you don’t have these assets, you’ll need to acquire them separately. You can view the full tier breakdown and requirements to ensure your current Unity setup supports this avatar.
Why it’s on our radar
The inclusion of full source files—specifically Blender/FBX, PSD, and Substance Painter assets—sets this apart from standard “locked” avatar packs. Most $40 digital goods in this niche provide only the final FBX or a restricted Unity scene, but here you get the entire production chain to modify the geometry and textures.
Additionally, the pre-configured Quest variant is a rare inclusion. Many high-spec avatars ignore mobile optimization, forcing buyers to do the heavy lifting themselves. By shipping a ready-to-go Android SDK setup alongside the desktop version, Ghostly [ Mama-Gen ] addresses a specific pain point for creators who need their avatar to perform consistently across both PC and Quest headsets.
What actually matters
Before you checkout, verify that your current Unity environment can handle the specific dependencies listed. The avatar requires VRC SDK Avatar 3.0 and the Poiyomi Shader. If you are still running Avatar 3.0 Beta or using a different shader stack, you will need to migrate your setup first.
Facetracking is a critical component for immersion, and this model relies on the JerryFaceTracking Template. Ensure you have this asset or are willing to purchase it separately; without it, the facial animation workflow will be incomplete.
Finally, check the tier requirements against your project scope. If you only need the base model with standard tracking, Tier 1 is sufficient. However, if you want the unique Milk-Pump unit and maternity sliders, you must select Tier 3. The listing is strict about no refunds, so confirm your tier choice carefully.

FAQ
Do I need to own specific Unity assets before buying Ghostly [ Mama-Gen ]? Yes. The listing explicitly requires VRC SDK Avatar 3.0, Poiyomi Shader, VRCFury SPS (Tier 2+), and the JerryFaceTracking Template. You will need to have these installed in your project for the avatar to function correctly.
Can I customize the model after purchase? Yes. Because the package includes Blender/FBX source files, PSD textures, and Substance Painter files, you are allowed to edit and customize the model for personal use. You can modify the armor, change RGB colors, or adjust the geometry as long as you do not resell or redistribute the original files.
Is the Quest version included in the base price? Yes. The package includes a Quest variant that is set up with the Android SDK in Unity. This means you don’t need to manually optimize the model for mobile performance; it is ready to compile for Quest 2/3.
Are there any restrictions on using the avatar? You can use it for streaming, v-tubing, and on other social platforms like Resonite or Chillout VR for personal use. However, you must not claim the model as your own work, use it for commercial purposes, or redistribute the source files. Credit is required whenever possible.
Bottom line
Ghostly [ Mama-Gen ] is a specialized tool for VRChat creators who want to skip the modeling phase and jump straight into customization. At $40, the value lies in the included source files and the pre-configured mobile variant, saving you significant time in Blender and Unity. If you have the required Unity assets and are looking for a “motherly beast” aesthetic with high-tech armor, this is a solid starting point.
