Text Entry Limits

Free Text entries support generated text-style content such as labels, dividers, spacers, alignment, alert styling, and optional before/after icons. Icon Hug Text controls are available for centered text; left and right aligned text always keeps icons attached to the text, so those controls are disabled.

Not included:

Text entry presets

Entry Display And Tools

Included:

Entry label
Property ID for property entries
Description/tooltip where supported

Entry Tools section
Copy settings tools

Included:

Child appears or hides based on the parent entry value.
Parent/child hierarchy for visibility logic.

Not included:

Child Availability
Disabled-but-visible child behavior
Availability copy/sync tools

Dynamic Labels

Free Dynamic Labels are direct and value-driven.

Dynamic Label rows act as a priority list: the first matching row wins. Overlapping values are allowed, so you can keep a specific rule above a broader rule and use the visible row order to decide which label appears.

Included:

Dynamic Labels based on the same entry's value.
Numeric/value rules for supported property entries.

Not included:

Conditional by Other Entry
Boolean Dynamic Labels by Other Entry
Text Dynamic Labels
Dynamic Text rules
Nested/cross-entry dynamic label sources

Generated Layout

Free Generated Layout supports simple panel layout.

Included:

Import Entry List items into Generated Layout.
Safe Import option in the Generated Layout import menu.
Reorder generated rows.
Shared row groups.
Up to 3 items per shared row group.
Row height from 1 to 2.

The fixed left indent is on/off only. When enabled, it uses the built-in compact indent amount.

Editor Layout
Editor section reorder/hide controls
Display and precision settings
Entry List settings
Confirmation rule editor
Import/export section

Shortcuts

Free has no PropUI keyboard shortcuts.

There are no shortcut targets, shortcut buttons, shortcut keymap rows, or list-specific shortcut controls.

Import, Export, Defaults, And Presets

Free includes setup portability for the core Entry List and Generated Layout:

Export the current Free setup to JSON.
Import setup JSON exported by Full, Free, or Rigify.
Copy and paste setup JSON through the clipboard.
Preserve every entry type, entry option, hierarchy relationship, row, and row option that Free supports.
Report unsupported data instead of silently pretending it was imported.

When importing a Full or Rigify setup, Free keeps Float, Integer, Boolean, Array, and Text entries. Unsupported entry types are removed, compatible children are reattached to their nearest supported ancestor, and their layout items are removed. Sub-panels are flattened into the same ordered rows because Free has no sub-panel container. Row Boxes, advanced column weights, right insets, visibility targets, and per-entry storage overrides are reported and skipped.

Rows containing more than Free's three supported columns are split into consecutive rows without changing entry order. Advanced entry or layout options that need a Free equivalent are included in the import report.

Rigify shared bone storage can be adapted to the selected armature Object, which is the closest valid Free storage model. Per-entry Rigify bone overrides cannot be represented by Free and are reported as skipped.

Not included:

Bundle ZIP export
Bundle ZIP import
Generated .py ZIP export
Editor Settings JSON export/import
Entry presets
Type defaults
Full setup default
Saved editor defaults

Basic Workflow

Open the 3D View sidebar and find PropUI.
Choose an Object in Property Storage.
Add entries in the Entry List.
Configure the active entry.
Add entries into Generated Layout.
Arrange simple rows or shared row groups.
Set Sidebar Tab and Panel Title.
Press Generate UI.

Generate applies the managed custom properties to the chosen Object and registers the generated 3D View sidebar panel.

Full Addon

The full addon is for users who need advanced entry types, generated UI management, UI variants, shortcuts, setup bundles and generated-script export, custom branding, richer layout controls, alternate panel locations, more storage options, presets, defaults, and deeper cross-entry behavior.
