Troubleshooting

This page covers the most common issues and how to resolve them.

Shadows not visible

SymptomNo cloud shadows appear in the Game view.
CauseMissing Sun reference, profile not assigned, or (URP) depth texture disabled.
Solution
  1. Select the Cloud Shadows GameObject and verify a Directional Light is assigned to the Sun field.
  2. Ensure a Profile is assigned and Show Shadows is enabled.
  3. URP only: Select your URP Renderer Asset and enable Depth Texture. The inspector shows a warning if this is off.
  4. Check the Camera Layer Mask includes the layer of the camera that should render the effect.

Shadows appearing on ceilings or undersides

SymptomCloud shadows are projected on the underside of geometry (ceilings, overhangs).
CauseThe Top Down Only option is enabled, which skips the screen-space normal check.
SolutionDisable Top Down Only in the profile's Shadows section. This enables screen-space normal calculation to exclude upward-facing surfaces.

Cloud layer looks flat or unrealistic

SymptomThe visible cloud layer lacks depth.
CauseLow Thickness or missing Bump Map texture.
Solution
  1. Increase Thickness in the Clouds section for a more volumetric appearance.
  2. Assign a Bump Map texture in the General section. Sample textures are available in the Demo folder.
  3. Adjust Anisotropy and Light Intensity for more dynamic lighting.

Performance is lower than expected

SymptomFrame rate drops after enabling Cloud Shadows FX.
CauseThe screen-space normal pass (needed when Top Down Only is off) adds GPU cost.
Solution
  1. Enable Top Down Only if the camera always looks downward.
  2. Increase Distance Fade to reduce the rendered area.
  3. Lower Edge Noise if it is set high, as it increases texture sampling.
