Bevy components

This Blender addon gives you an easy to use UI to add and configure your Bevy components inside Blender !

automatically generates a simple UI to add/configure components based on a registry schema file (an export of all your Bevy components's information, generated) by the bevy_registry_export crate/plugin
no more need to specify components manually using custom_properties, with error prone naming etc
adds metadata to objects containing information about what components it uses + some extra information
uses Blender's PropertyGroups to generate custom UIs & connects those groups with the custom properties so that no matter the complexity of your Bevy components you get a nicely packed custom_property to use with ...
the ideal companion to the gltf_auto_export to embed your Bevy components inside your gltf files

Important: the tooling is still in the early stages, even if it is feature complete : use with caution!.

Installation:

grab the latest release zip file from the releases tab (choose the bevy_components releases !)

in Blender go to edit => preferences => install

choose the path where bevy_components.zip is stored

Configuration & overview

Before you can use the add-on you need to configure it

Bevy side

setup bevy_registry_export for your project (see the crate's documentation for that), and compile/run it to get the registry.json file

Blender side

Go to the new Bevy Components tab in the 3D view

click on the button to select your registry.json file (in the "configuration" panel)

the list of available components will appear

Use

Existing components & custom properties

If you already have components defined manualy in Blender inside custom properties you will need to define them again using the UI!
avoid mixing & matching: if you change the values of custom properties that also have a component, the custom property will be overriden every time you change the component's value
you can of course still use non component custom properties as always, this add-on will only impact those that have corresponding Bevy components

adding components

to add a component, select an object and then select the component from the components list: (the full type information will be displayed as tooltip)

click on the dropdown to get the full list of available components

you can also filter components by name for convenience

add a component by clicking on the "add component" button once you have selected your desired component

it will appear in the component list for that object

edit components

to edit a component's value just use the UI:

it will automatically update the value of the corresponding custom property

copy & pasting

you can also copy & paste components between objects
click on the "copy component button" of the component you want to copy

then select the object you want to copy the component (& its value) to, and click on the paste button.

It will add the component to the select object

if the target object already has the same component, its values will be overwritten

Additional components UI features

for large/ complex components you can toggle the details of that component:

Supported components

normally (minus any bugs, please report those!) all components using registered types should be useable and editable
this includes (non exhaustive list):
- enums (even complex ones !)
- complex structs, with various types of fields (including nested ones)
- lists/ vecs (here a vec of tuples)
- etc !

Unregistered types & error handling

non registered types can be viewed in this panel : (can be practical to see if you have any missing registrations too!)
if you have a component made up of unregistered structs/enums etc, you will get visual feedback & the component will be deactivated

important ! gltf_auto_export currently has no way of filtering out components, so you need to delete invalid components like these before exporting this will be adress in the future
if you are encountering this type of view: don't panic your component data is not gone ! It just means you need to reload the registry data by clicking on the relevant button

advanced configuration

there are also additional QOL features, that you should not need most of the time
- "update custom properties of current object" : will go over all components that you have defined for the currently selected object, and re-generate the
corresponding custom property values
- "update custom properties of ALL objects" : same as above but it will do so for the ALL objects in your blend file (so can be slow!), and re-generate the
corresponding custom property values

Additional important information

for the components to work correctly with bevy_gltf_components or bevy_gltf_blueprints you will need to set the legacy_mode for those plugins to FALSE as the component data generated by this add on is a complete, clean ron data that is incompatible with the previous (legacy versions). Please see the documentation of those crates for more information.

Note: the legacy mode support will be dropped in future versions, and the default behaviour will be NO legacy mode
