This asset contains an easy to use Blueprint to quickly add cinematic volumetric fire to your scene. It uses a highly detailed VDB sequence that was imported as a Sparse Volume Texture (SVT) and offers customizability to dial in the look to your liking!

Watch a demonstration here.

Works with Lumen & Path Tracing, but keep in mind that you will only get screen space reflections and illumination with Lumen! For full effect, the Path Tracer is recommended.

This product contains:

• Easy to use Blueprint (Plug & Play)

• Highly detailed SVT / VDB sequence at 30fps max

• Custom Heterogeneous Volume Material and Material Instance

• Remap Curves for a realistic fire look (Curve Atlas)

• Lights for Lumen rendering (controllable through BP)

BP Features:

• Control Fire Brightness

• Temperature Min and Max Remap

• Switch Blackbody (Color Temperature) or stylized Fire Color

• Enable / Disable Lights

• Control Smoke Density

• Enable / Disable Playing (for Sequencer)

Troubleshooting

Path Tracing: If you experience blocky shapes or reduced quality compared to Lumen you can try these console variables:

• r.HeterogeneousVolumes.Tessellation.FarPlaneAutoTransition 0

• r.HeterogeneousVolumes.FrustumGrid.ShadingRate 2

• r.HeterogeneousVolumes.FrustumGrid.MaxBottomLevelMemoryInMegabytes 512

This will hard set the quality for the Heterogeneous Volume and will allocate more memory to render the volume. For a final render using the Movie Render Queue I would set the Shading Rate to 1 and the Memory to the maximum of 1792 to get the maximum quality.

This asset is meant for cinematics and filmmaking, which is why the sequence is capped at 30 fps. At the time of creating this asset SVT's are still in Beta and don't offer full functionality! Be aware of the performance hit, if you like to include it in your game.
