Fire Drill Smoke Simulation on Meta Quest 3 with Unity and Blender

Hello, I am a high school student in Japan working on a school project to simulate fire drills using Meta Quest 3, Unity, and Blender.

I am trying to display realistic smoke simulations on the Meta Quest 3. I created the smoke in Blender using its fluid/particle simulation system, but I’m running into multiple issues when trying to bring it into Unity:

• I cannot export the smoke simulation from Blender in a format that Unity natively supports while maintaining the volumetric effect.

• Even when importing .abc (Alembic) files into Unity with a compatible package, they do not render on the Meta Quest 3.

• I also tried using Unity’s Visual Effect Graph to simulate smoke, but it doesn't display on the Meta Quest 3 either.

I would like to know how I can properly display smoke simulations on Meta Quest 3—whether that’s by fixing the current workflow or using an alternative method (e.g., baked volumetrics, custom shaders, or third-party assets optimized for Quest).

Any guidance or recommended practices would be greatly appreciated.

Thank you very much.
