Auto export

• the original blueprints & levels path are now left as is, and there is an auto injection of xxxpath_full for absolute paths

  • replace all uses of the paths with the correct ones above
    • levels
    • blueprints
    • materials

• move out the UI for "assets" folder out of "blueprints condition"

• fix asset path calculations

  • root path => relative to blend file path
  • asset path => relative to root path
  • blueprints/levels/blueprints path => relative to assets path

• add error handling for de/serialization of project, so that in case of error, the previous saved serialized project is thrown away

• move out some parameters from auto export to a higher level (as they are now used in multiple places)

  • main/ library scene names
  • paths

• Data storage for custom properties:

  • for scenes (main scenes)
    • at scene level
  • for blueprints
    • at collection level
    • Note: these should be COPIED to the scene level when exporting, into the temp_scene's properties

  NOTE: UP until we manage to create a PR for Bevy to directly support the scene level gltf_extras, the auto exporter should automatically create (& remove) any additional object with scene_<scene_name>_components to copy that data to

Assets: - blueprint assets should be auto_generated & inserted into the list of assets : these assets are NOT removable by the user - should not change the list of manually added assets

• store assets
  • per main scene for level/world assets
  • per blueprint for blueprint in lib scene
• UI:
  • we need to display all direct assets (stored in the scene)
  • indirect assets:
    • QUESTION : do we want to include them in the list of assets per level ?
      • this would enable pre-loading ALL the assets, but is not ideal in most other cases
      • so add an option ?
    • the assets of local blueprints

Blueprints: - [x] on save: write IN THE COLLECTION PROPERTIES - list of assets - export path - [x] blueprint selection for nested blueprints is broken

- [ ] scan & inject on load
- [ ] scan & inject on save
- [ ] decide where & when to do & store blueprints data

Components: - [x] add support for adding components to collections - [x] upgrade all operators: - [x] add - [x] remove - [x] copy & paste - [x] BLENVY_OT_component_rename_component - [x] BLENVY_OT_component_fix - [x] add handling for core::ops::Range & other ranges - [x] fix is_component_valid that is used in gltf_auto_export - [x] Hashmap Support - [x] fix parsing of keys's type either on Bevy side (prefered) or on the Blender side - [x] fix weird issue with missing "0" property when adding new entry in empty hashmap => happens only if the values for the "setter" have never been set - [ ] handle missing types in registry for keys & values - [x] adding a hashmap nukes every existing component ?? - [x] Add correct upgrade handling from individual component to bevy_components - [x] Settings handling: - [x] move saveable settings out to a settings file - [x] update save & load - [x] add handling of polling frequency & enabling - [x] move advanced tools to components tab - [x] remove most of the (bulk) advanced tools, too complex, too unclear (even for me !) and of limited use - component renaming should be kept, but perhaps simplified: - if a renaming fails because the parameters are incompatible, nuke the old parameters - perhaps just add a display list of all NON component custom properties, so the user can find them easilly ? - [x] status "unregistered" is often false and misleading -> see in registry ui "for custom_property in object.keys():" - [x] overhaul / improve the component selector (with built in searching, etc) - [x] remove select_component_name_to_replace - [x] display of invalid components is not working ? - [x] weird items are present in the components list that do not seem to be components - [x] remove : - BLENVY_OT_component_list_add_item - BLENVY_OT_component_list_remove_item - BLENVY_OT_component_list_select_item: merge it into the rest of the actions - [x] clearing invalid flag after a registry change does not work correctly (ie the ui still says the component is invalid) - [x] should reset ALL "invalid" flags IF they have the matching data - [x] registry auto reload not working ? - [x] changing the registry breaks all the values of existing components !!!!!! -> VERY likely due to the int-offset computation for hashes of components - now switched to tiger_hash - [x] add warning about hash colision (not much we can/ could do if it is the case ?) - [x] double check weird collisions AND/OR reuse existing if applicable - [x] annoying default path for registry, should be relative to the assets path

General things to solve:

• save settings

• load settings

  • add blueprints data

• rename all path stuff using the old naming convention : "blueprints_path_full"

• generate the full paths directly when setting them in the UI

  • problem : how to deal with defaults: do it on start/load ?

• filter out scenes that have already been used in scenes list

General issues:

• there is no safeguard for naming collisions for naming across blender files

• this can cause an issue for assets list "parent"

• "parents" can only be blueprints

  • they normally need/have unique export paths (otherwise, user error, perhaps show it ?)
  • perhaps a simple hashing of the parent's path would be enought

• addon-prefs => settings

• generate_gltf_export_settings => should not use add-on prefs at all ? since we are not overriding gltf settings that way anymore ?

• remove hard coded path for standard gltf settings

• load settings on file load

  • auto_export
  • components
  • add handling of errors when trying to load settings

• fix auto export workflow

• add hashing of modifiers/ geometry nodes in serialize scene

• add ability to FORCE export specific blueprints & levels

• change scene selector to work on actual scenes aka to deal with renamed scenes

  • remove get_main_and_library_scenes as it should not be needed anymore

• fix asset file selection

• change "assets" tab to "levels"/worlds tab & modify UI accordingly

• remove local assets, useless

• remove 'export_marked_assets' it should be a default setting

• disable/ hide asset editing ui for external assets

• fix level asets UI

• remove BlueprintsList & replace is with assets list

• switch to bevy 0.14 rc2

• trigger events when assets are loaded, blueprints are spawned & co

• overall cleanup

  • object.add_bevy_component => blenvy.component_add

• inject_export_path_into_internal_blueprints should be called on every asset/blueprint scan !! Not just on export

• undo after a save removes any saved "serialized scene" data ? DIG into this

• handle scene renames between saves (breaks diffing) => very hard to achieve

• force overwrite of settings files instead of partial updates ?

• add tests for disabled components

• should we write the previous _xxx data only AFTER a sucessfull export only ?

• add option to 'split out' meshes from blueprints ?

  • ie considering meshletts etc , it would make sense to keep blueprints seperate from purely mesh gltfs

• persist exported materials path in blueprints so that it can be read from library file users

  • just like "export_path" write it into each blueprint's collection
  • scan for used materials per blueprint !
  • for scenes, scan for used materials of all non instance objects (TODO: what about overrides ?)

• find a solution for the new color handling

• add back lighting_components

• check if scene components are being deleted through our scene re-orgs in the spawn post process

• should "blueprint spawned" only be triggered after all its sub blueprints have spawned ?

• simplify testing example:

  • remove use of rapier physics (or even the whole common boilerplate ?)
  • remove/replace bevy editor pls with some native ui to display hierarchies

• try out hot reloading

• simplify examples:

  • a full fledged demo (including physics & co)
  • other examples without interactions or physics

• update main docs

  • rename project to Blenvy
  • replace all references to the old 2 add-ons with those to Blenvy

• rename repo to "Blenvy"

• do a deprecation release of all bevy_gltf_xxx crates to point at the new Blenvy crate

• hidden objects/collections not respected at export !!!
