With the release of Unity 6, the VFX Graph provides a dedicated Output Decal context. This feature allows the system to write directly to the D-Buffer or render in the forward decal pass, ensuring that particles behave as decals on geometric surfaces.

1. Open your VFX Graph and create a new system or modify an existing one.
2. Remove standard mesh or quad outputs and add an Output Decal context.
3. Create a new Shader Graph and set the Material Type to Decal in the Graph Settings.
4. Assign this Shader Graph to the Output Decal context within the VFX Graph.
5. Configure the Output Decal attributes, such as Size and Fade, to control how individual particles project onto world geometry.

Additional Tips

• Ensure the Universal Render Pipeline Asset has the Decal Renderer Feature added to its Renderer List.
• For optimal performance, utilize D-Buffer rendering when targeting platforms that support it to minimize draw calls.
• You can still use the Output Decal to control depth bias and prevent z-fighting on overlapping particle decals.
