In this tutorial, ChrisP introduces you to the new Volume Grids feature in Blender 5, which allows you to access volumetric simulations like smoke and fire inside Geometry Nodes.

Creating a Smoke Simulation

• Create an icosphere and apply quick smoke.
• Adjust the smoke domain settings.
• Animate the smoke inflow for a single puff effect.
• Add turbulence for more dynamic smoke.

Baking the Simulation

• Set the cache settings and bake the simulation.
• Save the VDB files for use in Geometry Nodes.

Using Volume Grids in Geometry Nodes

• Import the VDB files into Blender.
• Access the density and velocity data from the VDB files.
• Visualize the density grid by distributing points and instancing objects.
• Create a mesh and manipulate it based on the smoke simulation.

Advanced Techniques

• Use the velocity vector to influence mesh movement.
• Adjust the size of instanced objects based on density.
• Manipulate the velocity vectors for additional effects.

By the end of this tutorial, you’ll have a solid understanding of how to use Volume Grids in Blender 5 to create stunning animations with Geometry Nodes.
