kaosat.dev 31f6a0f122 feat(blenvy:blender): a ton of cleanups, fixes & improvements
* fixed bad hashing causing hashed project across two different blender sessions to appear different
 aka, no more systematic re-export of everything when reloading a project in blender !
 * fixed issues with modifier & material hashing that was also causing overly eager change detection
 * previous_xxx_settings are now only saved AFTER a sucessfull export, for coherence
 * added more fine grained setting change detection (aka some setting changes do not require a re-export of all levels & blueprints !)
 * fixed handling of level & library scene names as part of the settings
 * fixed numerous issues with core, auto_export & component settings
 * cleaned up a ton of very verbose debug message
 * BlenvyAssets => BlueprintAssets
 * a lot of minor cleanups

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

Blender side:

  • force overwrite of settings files instead of partial updates ?
  • prevent loop when loading/setting/saving settings
  • fix asset changes not being detected as a scene change
  • fix scene setting changes not being detected as a scene change
  • add back lighting_components
  • check if scene components are being deleted through our scene re-orgs in the spawn post process
  • fix unreliable project hashing between sessions: (note, it is due to the use of hash() : https://stackoverflow.com/questions/27522626/hash-function-in-python-3-3-returns-different-results-between-sessions)
  • figure out why there are still changes per session (it is due to object pointer being present in the generated "hash")
    • materials & modifiers, both using the same underlying logic
      • filter out components_meta
      • filter out xxx_ui propgroups
  • fix missing main/lib scene names in blenvy_common_settings
  • fix incorect updating of main/lib scenes list in settings
  • and what about scene renames ?? perhaps tigger a forced "save settings" before doing the export ?
  • should we write the previous _xxx data only AFTER a sucessfull export only ?
  • finer grained control of setting changes to trigger a re-export:
    • common: any of them should trigger
    • components: none
    • auto_export:
      • auto_export: yes
      • gltf settings: yes
      • change detection: no ?
      • export blueprints: YES
        • export split dynamic/static: YES
        • export merge mode : YES
        • materials: YES
  • 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
  • add tests for disabled components
  • find a solution for the new color handling
  • hidden objects/collections not respected at export !!!
  • 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 ?)

Bevy Side:

  • deprecate BlueprintName & BlueprintPath & use BlueprintInfo instead
  • 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
  • add a way of overriding assets for collection instances
    • add a way of visualizing per blueprint instances
  • cleanup all the spurious debug messages
  • fix animation handling
