[HDRP] Adaptive Probes Static on Dynamic Spawns

Under Audit

Unity 2022.3.x - Unity 6.1.x

Published Mon, Mar 16

Characters in HDRP procedurally generated environments may not receive correct dynamic lighting from adaptive probes when moving through spawned prefabs. The lighting appears fixed to the initial environment position.

Issue

 When utilizing Adaptive Probe Volumes in HDRP for environments with procedurally generated elements, such as spawned prefabs, dynamic lighting may not correctly apply to moving characters. Despite static lighting being baked for the environment, the adaptive probes do not appear to dynamically update the lighting contribution for characters traversing these dynamic scenes. This results in lighting that seems to be fixed to the initial spawn position of the environment chunks, failing to provide consistent dynamic illumination as your controller moves through the generated level.

Experimental Fixes
  • Ensure Adaptive Probe Volumes are correctly placed and encompass the entire area where dynamic lighting is needed.
  • Verify that your character’s Renderer component has Receive GI set to Light Probes or Light Probes & Reflection Probes.
  • Check the Probe Volume parameters, such as Cell Size and Blending Distance, to ensure they are appropriate for the scale and dynamism of your environment.

Editor's Note:

The above fixes have not been verified by our audit team yet. They are provided exclusively for your own technical research. We recommend creating a backup of your project before proceeding with any attempts. Utilize at your own discretion!
