Fix Very Poor / Poor avatar rank on Quest & PC - Performance Rank Doctor [VRChat / Unity] (Free version)

Your avatar shows Very Poor or Poor, and on Quest nobody can see it?
The SDK tells you the rank, but not which item to fix first or how much it will help.

Performance Rank Doctor adds a window to Unity. Press Analyze and it shows:

• The estimated PC rank and Quest rank
• Every item that holds the rank down - with why it costs performance and how to fix it
• "Fixing this alone: Very Poor -> Poor overall" - how much each fix actually helps
• "To reach Medium: ..." - what you need to change to reach the next rank

What it checks

• Triangles, texture memory, skinned meshes, basic meshes, material slots, bones
• PhysBones: components, affected transforms, colliders, collision check count
• Contacts, constraints (VRChat and Unity), animators, lights
• Particle systems, max particles, mesh particle polys, trails, collision
• Trail / Line Renderers, Cloth, physics colliders, rigidbodies, audio sources

It also tells you

• Mesh Read/Write is off - VRChat can't count the triangles and ranks the whole avatar Very Poor. (Why this happens)
• Shaders Quest doesn't allow - Quest avatars can only use VRChat/Mobile shaders. (Details)
• Components removed on Quest - anything that relies on them won't work there
• Extra material slots - more slots than the mesh has parts draws the last part again
• The same material in several slots of one mesh
• Disabled meshes still count - outfits you never turn on still cost triangles, slots and textures
• On Quest, avatars below Medium are hidden by default, and above the Very Poor limits PhysBones are removed. (PhysBones not working on Quest)

Free vs Paid

Free ($0)

• PC and Quest rank estimate, item by item
• Why it costs performance & how to fix it
• How many ranks each fix gains
• Select the problem object / texture
• Copy the results to paste when asking for help

Paid ($5) - everything in Free, plus:

• 1-click: turn Mesh Read/Write on
• 1-click: compress textures and cap at 2048 / cap at 1024 for Android only
• 1-click: remove extra material slots
• Duplicate the avatar before scene fixes (original hidden)

Every change can be undone: texture and mesh import settings with the Revert last import change button, scene changes with Ctrl+Z (Cmd+Z on Mac).

Good for

• Your avatar is Very Poor / Poor and you don't know where to start
• You're making a Quest version and want it to reach Medium
• You want to know which fix actually changes the rank before spending time on it

Not for

• Reducing polygons or merging meshes automatically - the tool tells you where and how (e.g. with AAO: Avatar Optimizer or Blender), but doesn't do it
• Making a full Quest conversion (shader swap, etc.) automatically

Language

English and Japanese interface. It shows English automatically unless your Unity or OS language is Japanese, and you can switch with the "English / 日本語" toggle at the top of the window.

Install

1. Drag the .unitypackage into your project and Import
2. Open Tools > Performance Rank Doctor
3. Drag your avatar into the Avatar field (or select it) and press Analyze

Requirements

• Unity 2022.3 (the version VRChat uses) with the VRChat SDK (Avatars)
• Without the SDK it still runs, but PhysBones, Contacts and VRChat Constraints are counted as 0
• (Tested in Unity 2022.3.22f1 with VRChat SDK 3.10.5)

Notes

• Counts are estimates based on VRChat's published rank limits. The SDK's numbers are final.
• Numbers are before build-time tools run. Modular Avatar, AAO and VRCFury change the avatar during upload, so check the final rank in the SDK Build panel.
• Quest texture memory is estimated from the current build target. Switch to Android for exact Quest numbers.
• Analyzing never modifies your avatar. It only changes files when you press a fix button.
• Texture fixes change shared files: other avatars using the same textures change too.
• This is not an official VRChat tool.
• Digital product - no refunds after purchase. Bugs will be fixed in updates.
• Questions and bug reports: please send us a message on Jinxxy.
