Since lighting behavior can vary across Unity versions and render pipelines, you may need to adjust existing lights or add additional ones to achieve better-lit previews.

For HDRP projects, start by clicking “Reset to HDRP Default” in the Lighting Settings for both the Animation Clip Preview and the GameObject Preview.

If you switch your project from HDRP to URP, use “Reset to URP Default” to quickly apply suitable lighting for URP.
