Detailed Description
Packed render data for all smoke volumes. Created on Game Thread, consumed on Render Thread. Contains all data needed for rendering without accessing Volume actors.
THREAD SAFETY:
- Created on Game Thread in PrepareRenderData()
- Transferred to Render Thread via ENQUEUE_RENDER_COMMAND
- Consumed on Render Thread in Render() and RunPrePassPipeline()
DATA SAFETY WARNING: Some fields are REFERENCE-BASED and tied to UObject lifetime. See comments below for dangerous vs safe fields.
