Why this Blender add-on?

Blender is powerful, but common actions are often spread across menus, panels, and shortcuts. PsychoVertexMaster gathers them into a compact toolkit designed around how artists actually work.

Without it	With PsychoVertexMaster
Search through several menus	Open one context-aware menu
Repeat setup on every object	Apply actions across a selection
Build modifier stacks manually	Create configured modifiers in a click
Manage matching UV layers one object at a time	Update selected objects together
Leave Edit Mode for small utility jobs	Measure, color, select, and prepare in place

The idea is simple

Keep your attention on the model—not on finding the next button.

PsychoVertexMaster does not replace Blender's tools. It makes the best everyday ones faster to reach and adds focused helpers for the repetitive gaps between them.

Blender Handy Menu

Object Mode

Edit Mode

_{One shortcut, two context-aware layouts, dozens of useful Blender actions.}

The D menu is the center of PsychoVertexMaster. It groups actions by purpose and only shows the groups relevant to your current context.

Blender Edit Mode tools

🟦 UV tools

• generated collision visibility.

🟪 Optional Object History entry

If a compatible panel named DATA_PT_PsychoHistory_KM is registered, PsychoVertexMaster adds an Object History shortcut automatically. If it is not available, the entry stays hidden.

---

Blender Modifier Menu

Press W in the 3D View to create and manage modifiers with fewer setup steps.

Add modifiers

Modifier	Available behavior
Mirror	Adds a Mirror modifier on X, Y, Z, XY, YZ, XZ, or XYZ; enables clipping and uses a small merge threshold.
Array	Adds an array by fixed count, fit length, selected curve, or object offset.
Boolean	Adds an empty Boolean modifier to selected objects, or adds Boolean modifiers to the active object using the other selected objects as cutters. Cutters switch to wire display.
Shrinkwrap	Adds an empty Shrinkwrap modifier, or uses the active object as the target for the other selected objects.
Curve	Adds an empty Curve modifier or assigns a selected curve to the active object, with an option to move the object to the curve.
Bevel	Adds a Bevel modifier to every selected object.
Solidify	Adds a Solidify modifier to every selected object.
Skin	Adds a Skin modifier to every selected object.

Manage modifier stacks

Action	What it does
Expand All	Expands every modifier panel on selected objects.
Collapse All	Collapses every modifier panel on selected objects.
Apply All	Applies every modifier on each selected object.
Remove All	Removes every modifier from each selected object.

Tip: Apply All and Remove All change complete modifier stacks. Save first when working on important assets.

---

Blender UV management tools

PsychoVertexMaster extends the UV Maps panel in Object Data Properties. These controls are designed for selections containing several meshes that should share the same UV-layer structure.

Action	How it works
Move Up / Move Down	Reorders the active UV map in the list.
Add To All	Creates the name entered in New Name on every selected object that does not already have it.
Remove From All	Removes the active UV-map name from every selected object that contains it.
Select In All	Makes the matching UV map active across selected objects.
Rename In All	Renames matching active UV maps across the selection.

This is especially useful when several meshes must agree on names such as UVMap, Detail, or another pipeline convention.

Blender vertex-color tools

Vertex colors become a practical modeling tool instead of a panel-hunting exercise.

HSV Mouse Paint workflow

1. Enter Edit Mode and select vertices, edges, or faces.
2. Press D and open Vertex Color → HSV Mouse Paint.
3. Click or drag across the large square to set saturation and value.
4. Click or drag across the side strip to set hue.
5. Click outside the picker to accept or press Esc to cancel.

The tool temporarily switches viewport shading so the color is visible, supports point- and corner-domain color attributes, creates a Color corner attribute when necessary, and restores the previous display afterward.

Copy, paste, and match

• Copy turns the active face's average color into a portable hex value.
• Paste accepts #RRGGBB or RRGGBB from the clipboard.
• Select Matching finds faces with the same byte-level color as the active face.

---

Blender collision generator

Create Unreal-compatible collision helpers from a mesh selection in Edit Mode or from selected meshes in Object Mode:

Tool	Output	Best for
Add Box Collision	UBX_	Box-like forms using axis-aligned or PCA-oriented fitting.
Add Sphere Collision	USP_	Rounded objects using a fitted sphere.
Add Capsule Collision	UCP_	Elongated rounded forms using a fitted capsule.
Add Convex Collision	UCX_	Irregular forms using a convex hull.

For example, select at least three vertices in Edit Mode and run Add Box Collision. The tool:

1. analyzes the selected points;
2. compares an axis-aligned box with a PCA-oriented box;
3. uses the rotated result only when it provides a confident, meaningful improvement;
4. adds adjustable padding;
5. creates a separate collision object in the source collection;
6. converts it through the configured box-collision operation;
7. restores the original object and Edit Mode.

Use Display Collisions from the Handy Menu to switch recognized UBX_, UCX_, UCP_, and USP_ collision objects between visible solid display and hidden/wire display.

---

Blender origin and parenting tools

PsychoVertexMaster includes several ways to organize transforms without rebuilding hierarchies manually.

Tool	Best use
Origin to Selected	Place an object's pivot at chosen mesh geometry.
Fix Rotation	Derive a more useful origin and rotation from a mesh selection.
Set Origins To Active	Give several objects the same pivot location and rotation as the active object.
Create Empty Parent	Group the selection around the active object's transform.
Create Empty Parent (Foreach)	Wrap every selected mesh in its own named parent.
Create Empty Parent (Active)	Create one named root from the active object for the entire selection.

---

Blender Asset Browser tools

Make Collection Assets turns selected objects into individual collection assets:

• creates or reuses a collection named after each object;
• moves the object into that collection;
• marks the collection as an asset;
• generates an asset preview;
• removes the old collection when it becomes empty.

It is a fast way to convert scene objects into reusable library pieces.

---

Blender FBX import and batch export

Standard FBX access

The Handy Menu exposes Blender's regular Import FBX and Export FBX actions near the rest of the asset-preparation tools.

Batch Export Selections as SM_

This helper exports every selected object as a separate FBX file:

• output names follow SM_ObjectName.fbx;
• each object is exported individually;
• location and rotation are temporarily cleared for export;
• the operation uses Blender's FBX exporter;
• an undo step restores the working scene afterward.

Blender for Unreal helpers

When Blender for Unreal is installed, the To Unreal menu can:

• prepare selected objects for recursive export;
• set or clear export status;
• update export paths from collection hierarchy;
• configure collision, material search, rotation, Nanite, and light-map export properties used by that integration.

---

Child Control

The Child Control panel lives in the 3D View sidebar. For selected parent objects, it groups direct children by the prefix before _ and provides quick controls to:

• toggle a child hierarchy's viewport visibility;
• select a visible child;
• open Blender's rename panel for that child.

Children inside collections that disable selection are omitted, keeping protected scene structures out of the panel.

---

Custom lightmapping workflow

PsychoVertexMaster includes a batch-oriented lightmapping pipeline for preparing Blender assets, sharing a packed LightMap UV space, baking Cycles lighting, denoising the result, assigning final EXR lightmaps, and preparing generated assets for Unreal Engine workflows.

Feature overview

• Treat each direct child of a top-level SOURCE collection as one independent bake batch.
• Realize collection instances while preserving object hierarchies, lights, collision helpers, material-slot order, and shadow-visibility behavior.
• Pack eligible meshes together with per-face lightmap_scale control and optional pixel-perfect UV alignment.
• Bake multiple receivers into one persistent full-resolution noisy EXR per batch.
• Denoise before or after premultiplied downsampling, with controllable final-pixel margins.
• Use Blender's integrated denoiser, Open Image Denoise, the supported OptiX executable, or no denoising.
• Replace repeated filler instances from prepared batches without adding them to later bakes.
• Preview baked lighting and clean either one generated batch or the complete generated workspace.

Requirements

• Blender 4.2 or newer for the complete workflow. Passthrough materials use the Ray Portal BSDF introduced in Blender 4.2.
• UVPackmaster 3 for the custom UV packing operations.
• A saved .blend file and permission to write its Lightmaps directory.
• Mesh receivers with a UV layer named LightMap.
• Materials explicitly marked for light baking, passthrough, or full transparency as needed.
• For external denoising, either use the preference download buttons or choose compatible executables manually.

Basic workflow

1. Create SOURCE; make each direct child collection a separate intended bake batch.
2. Add a LightMap UV layer to meshes that should receive baked lighting and configure their material light-baking roles.
3. Optionally set per-face lightmap scale in Edit Mode; 1 is normal density and 0 removes useful lightmap area.
4. Run Unpack Collections to generate prepared EXPORT_STUFF/BatchN collections and pack their UVs.
5. Activate a generated batch in the Outliner and run Bake Batch.
6. Keep that batch active and run Denoise Batch to write and assign its final lightmap.
7. Optionally replace FILLERS, toggle the lighting preview, then export or clean generated data.

See the complete lightmapping guide for collection setup, material roles, packing controls, baking, denoising, fillers, troubleshooting, and cleanup behavior.

Where to find the controls

• Press D or W in the 3D View and open Lightmapping.
• Edit Mode provides Set Lightmap Scale and Scaled UV Packing.
• Object Mode—or no active object—provides unpack, repack, bake, denoise, filler, and cleanup operations.
• Open Material Properties → Light Baking to choose Light Baked, Passthrough, or Fully Transparent. Choose only one role per material.
• Batch-sensitive operations use the active collection in the Outliner, not merely the selected object.

---

Preferences

Open Edit → Preferences → Add-ons → PsychoVertexMaster.

Mode	Experience
Pie Menus	Fast radial navigation designed for muscle memory. This is the default.
Normal Menus	A conventional multi-column layout for users who prefer visible lists.

Menu configuration

Customize independent Handy Menu layouts for Edit Mode, Object Mode, and No Active Object. Each context can contain up to eight enabled slots while retaining additional disabled entries for later use.

• Reorder, enable or disable, and remove entries directly from each row.
• Rename custom entries and choose their Blender icons with the visual icon picker.
• Open and edit nested submenus through the breadcrumb navigation.
• Add built-in PsychoVertexMaster actions, custom Blender operators, safe property controls, separators, or submenus.
• Import, export, or reset the complete menu configuration with the header controls.

Layouts persist in Blender's add-on preferences. Import and export use JSON files for backup or transfer. The eight-slot limit applies only to enabled entries in each individual menu; additional entries may remain configured but disabled.

The shipped layout stores ordinary Blender operators and RNA properties as editable custom entries, keeping Plugin Action focused on PsychoVertexMaster and curated integration features. Existing installations can adopt the latest defaults with Reset Menu Configuration.

External lightmap denoisers

The preferences include compact executable paths for OIDN and OptiX. You can select an existing executable, or use the two download buttons beneath the paths:

• Download Open Image Denoiser installs Intel Open Image Denoise 2.5.1, including its required DLLs, inside the add-on's denoisers folder.
• Download OptiX Denoiser installs Declan Russell's compatible Denoiser.exe in the same folder.

Downloaded executables become the defaults automatically. A manually selected path always takes precedence. Internet access and write permission to the installed add-on directory are required for downloading.

External denoising is optional, and installing either backend is sufficient—you do not need both. The download buttons install 64-bit Windows builds. OptiX also requires a compatible NVIDIA GPU and driver; release 3.0 requires NVIDIA driver 565 or newer. On other operating systems, choose a compatible OIDN executable manually where supported; the supplied OptiX adapter expects the Windows Denoiser.exe application.

These denoisers are currently used only by PsychoVertexMaster's custom lightmapping workflow; they do not affect Blender renders or other add-on tools. More denoising uses may be added later. OIDN is preferred when external denoising is enabled because it provides the dedicated RTLightmap filter used by this workflow.

Both downloads come directly from third-party GitHub releases and are not developed or bundled by PsychoVertexMaster. Intel Open Image Denoise is distributed under Apache 2.0; Declan Russell's NVIDIA AI Denoiser is distributed under the MIT License. Their upstream requirements and licenses apply.

Updates

PsychoVertexMaster checks the repository's latest stable GitHub Release in the background shortly after Blender starts. When a newer version is available, the update dialog provides:

• Update to validate and install the release;
• Cancel to leave the current installation unchanged;
• Don't show again for this update to suppress that exact release while allowing alerts for later releases.

Use Check for Updates at any time for a manual check. Automatic Alerts is enabled by default; turn it off to disable startup update checks and dialogs completely. Manual checks continue to work while automatic alerts are disabled.

Updates preserve downloaded denoisers and local backup data. After a successful installation, restart Blender to load the new version. Release tags must match the version embedded in the add-on, so only properly versioned stable releases are accepted.

---

Installation

Blender compatibility

• General add-on metadata declares Blender 3.0 or newer.
• The complete custom lightmapping workflow requires Blender 4.2 or newer because passthrough materials use the Cycles Ray Portal BSDF.
• Features that do not use Ray Portal may continue to work on earlier versions, but should be tested against the exact Blender release.

1. Click Code → Download ZIP on this GitHub repository.
2. Ensure the ZIP contains the PsychoVertexMaster folder with its root __init__.py.
3. Open Blender.
4. Go to Edit → Preferences → Add-ons.
5. Choose Install from Disk and select the ZIP.
6. Enable PsychoVertexMaster.
7. Move your cursor over a 3D View and press D or W.

Updating

Use Check for Updates in the add-on preferences, or accept an automatic update alert. Restart Blender after installation. You can still update manually by disabling or removing the previous version, installing the new release ZIP, and restarting Blender.

---

Optional integrations

The core toolkit works without these add-ons. Install them only for the related actions.

Integration	What it unlocks
EdgeFlow	Set Flow for selected edge loops.
Blender for Unreal	The To Unreal setup, export flags, and path tools.
Blender FBX importer/exporter	FBX import, export, and separate SM_ batch export. Usually bundled with Blender.

Some tools rely on Blender-version-specific API features. If an action fails, include your exact Blender version when reporting it.

---

FAQ

Is PsychoVertexMaster free?

Yes. It is free and open source under the MIT License.

Do I need every optional integration?

No. The related menu action is the only part that needs it. The rest of the add-on remains useful on its own.

Can I use normal menus instead of pie menus?

Yes. Change Mode in the add-on preferences from Pie Menus to Normal Menus.

Why does a tool depend on selection or mode?

PsychoVertexMaster is context-aware. Mesh-editing actions expect Edit Mode, object organization actions expect Object Mode, and several tools use the active object as their source or target.

How should I report a bug?

Include your Blender version, operating system, current mode, selection, the action you ran, what you expected, and the complete console error. A small sample .blend is especially helpful when it can be shared safely.
