Currently, the first time a raycast is attempted for a model, the raycast will fail and the model's kdtree will asynchronously get built. This breaks the vegetation system, which expects the queries to always work. This adds in a brute-force fallback for use while the kdtree is building. However, other use cases like the Editor mouse cursor selection raycast still should get the current "silent failure" behavior, because otherwise the Editor will lock up for several seconds the first time the mouse moves over an extremely complex model.
* [LYN-3099] Fix vegetation raycasts to use bounded ray queries instead of FLT_MAX.
Raycasts with a distance of FLT_MAX sometimes overflowed deep in IntersectSegmentTriangleCCW, so it's better to have strict start/end positional queries. We have specific starts and ends anyways, so it's a safer approach anyways.
This also adds support for Non-Uniform Scale for meshes, since it was clearly not working correctly in vegetation when testing various scaled meshes.
* Addressed PR feedback
* Removed a bit of dead legacy code
* Fixed entity references during spawning
Entities that had references to other entities that hadn't been spawned yet weren't getting their IDs remapped correctly, since the new ID wasn't available yet. By pre-generating the full set of IDs, the references now remap correctly.
* Fixed up Entity References to work across multiple SpawnEntities calls
With SpawnEntities, entity references need to forward-reference to the *first* entity spawned, then from that point on backwards-reference to the *last* entity spawned. Added that logic, along with some initial unit tests for SpawnAllEntities.
* Added more unit tests for SpawnEntities / SpawnAllEntities
* First version of prefab support for dynamic vegetation
* Addressed PR feedback
- Made MockSpawnableEntitiesInterface a proper GMock in AzFramework
- Added Get/SetSpawnableAssetId
- Added lots of comments to better explain things that were asked about in the PR
* Exposed AzFrameworkTestShared on all platforms, not just host platforms
Several UI property handlers were incorrectly using the autoDelete feature by calling UnregisterPropertyType and deleting the pointer themselves, which caused double-delete crashes on application shutdown. PropertyManagerComponent now gracefully handles that condition but also explicitly asserts explaining how the code should be changed, and the "known offenders" have been fixed up to use autoDelete correctly.
Delete:
- I3DEngine
- Missions
- Time of day
- GameEffectsSystem Gem
- ImageProcessing Gem
- SVOGI Gem
- Various other things that don't do anything now that the legacy renderer has been removed.
By setting the initialization flag before the CheckReady() call, the notifications get sent correctly, and no extra asset references remain. This checkin also includes a unit test for the AssetManager that specifically forces this condition to happen and validates that it works correctly.
The actual bug was the "if (!m_engine)" early-out in CreateInstanceNode that needed to be removed, but all the rest of this legacy-based merged mesh code was ripe for removal as well.
* Added clone methods for the buffer, model lod and model assets.
* Cloning works via the creators.
* Mesh handle/instance now knows about the model asset it originated from as well as the cloned model asset that we need for instancing until instancing works without the dependencies to the asset ids.
* MeshComponentRequestBus returns the original asset id and the model asset. If you need access to the clone, go by the model.
* Cloth component mesh now gettings its model asset from the model as it needs to work on the clone.
* Moved the requires cloning function from the mesh loader in the mesh feature processor to the mesh component controller.
* As we need the model asset to be loaded before we can check if it requires cloning or not, we couldn't pass in a bool from the controller but had to use a callback.
* Using asset hint instead of asset id for the model lod asset creator error.
* Storing a map of source buffer asset ids and the actual cloned buffer assets rather than just their ids.
* Using the buffer assets from the new map directly and removed the search process in the mesh loop where the asset views are created.
* Fixed the vegetation mocks.
* Using the actor's mesh asset when emitting the on model ready event for the mesh component notification bus.
* Mesh components notifications connection policy changed to adapt to cloned model asset.
* Handling empty meshes in model lod asset creator.
* Removed the requires cloning callback from the mesh feature processor and made it a parameter to the acquire mesh function
* Fixing mocks and unit tests
