FAQ

This version is exclusively for the Universal Render Pipeline (URP). For Built-in pipeline projects, use the Built-in version of Volumetric Lights 2.

Unity 2022.3 LTS or later is required.

Spot, Point, and Area (both Rectangle and Disc) lights are supported. Directional lights are not directly supported, but you can simulate directional volumetric fog using a large area light with the VolumetricLightDirectionalSync helper component.

Yes. Each light is independent and has its own settings. Use the Composition Blur Render Feature for optimal blending of multiple lights.

Yes. The asset runs on iOS and Android. Use Simple light mode and lower ray-march quality for best performance. See Performance Tips.

Yes. Both single-pass instanced and multi-pass rendering are supported. Keep ray-march quality low and use the Render Feature downscaling for best VR performance.

Profiles are ScriptableObject assets that store all volumetric light settings. Assign the same profile to multiple lights to share configuration. Changes to the profile propagate automatically when Profile Sync is enabled.

Shadow cost depends on resolution and bake interval. Setting Shadow Bake Interval to OnStart makes shadows essentially free at runtime. For real-time shadows, use the lowest resolution that looks acceptable (256 is often enough).

Yes, with a small shader modification. See Orthographic Camera Support.

Yes. All Kronnect assets are fully compatible with Unity 6. The minimum supported version is Unity 2022.3 LTS, and this includes Unity 6 and any newer releases.

The volumetric light shadow capture system is incompatible with Shadows Only pass. Instead, create a custom layer (e.g., 'Shadows Only') and assign your shadow-casting objects to it. Exclude this layer from the main camera's culling mask but include it in the volumetric lights inspector's shadow culling mask settings.

Ensure both the Shiny SSRR Render Feature and Volumetric Lights Render Feature are set to 'After Transparents' in the render pipeline, with Volumetric Lights positioned just below Shiny SSRR in the render feature order. Verify in the Frame Debugger that Volumetric Lights Render Feature runs after Shiny. Additionally, set the Reflections component on the volumetric light to 'Ignore' to prevent the light cone from being included in SSRR reflections. You may need to exit playmode and restart for changes to take effect.

Add the Reflections component to the volumetric light and set it to 'Ignore'. This will exclude the light cone from SSRR reflections even if the TransparentFX layer is included in SSRR's layer mask. Verify the setting is applied by checking the Frame Debugger to ensure the cone is not being included in reflections.

Set the material render queue to a value higher than the Volumetric Lights default material (3101). For example, use render queue 3150 for materials that should appear in front. Alternatively, if using the volumetric lights render feature, configure it to render before transparent objects.

Ensure you have Depth Texture enabled in your URP asset settings. For Rect Area lights specifically, check that shadows are enabled and try increasing the shadow intensity. Also verify the light is oriented correctly (not rotated against the blocking object) - Rect Area lights need proper positioning relative to obstacles for shadows to render correctly.

When experiencing shadow artifacts with volumetric lights in URP, try using the volumetric lights render feature instead of the standard rendering path. You can also try toggling the depth setting in the inspector, though the render feature approach is recommended.

Ensure the Mesh Renderer for the volume (sphere or other shape) is using the shader provided by the VolumetricLight component, not the standard Lit shader. Using an incorrect shader will prevent the volumetric effect from displaying. If unsure about the correct setup, drag a light prefab from the demo scene to see the proper configuration.

Use the 'Auto Toggle' setting in the inspector. It's located in the Rendering section (last option) and will automatically toggle the light effect based on distance. Make sure you're using the latest version of the asset.
