This Project includes feature sample Scenes, stress test Scenes, and unit tests for the HDRP Hybrid Renderer.
The feature sample Scenes are in the SampleScenes folder. Most of these Scenes include GameObjects in a SubScene.
Unity renders GameObjects with the Hybrid Renderer when a coresponding DOTS entity exists, and without the Hybrid Renderer when a corresponding DOTS entity does not exist. For the GameObjects in the SubScene, this means that Unity renders them with the Hybrid Renderer at all times; in Edit Mode, in Play Mode, and in the built player.

Stress test Scenes are located in the StressTestScenes folder.
The BigBatches stress test measures maximum thoughput of perfectly batched content. StressTestGameObjects uses GameObjects, and StressTestHybrid uses the Hybrid Renderer. This allows you to measure performance differences between GameObject rendering and Hybrid Rendering.
The stress test scene contains 100,000 spawned boxes. They cycle though four different animation modes: no animation, color animation, position animation, color + position animation.
StressTestGameObjects has two variants: one that includes the color overrides, and one that does not incude color overrides. This is because modifying GameObject color requires Material changes per GameObject, which causes material replication per object and has a large performance impact. Providing a variant without color overrides demonstrates more realistic performance for cases where you only modify position.
Compatible with Unity 2022.2.0b8 and HDRP 14.0.3 or later.\
