The project is based on the lesson course, in which 3 URP assets were created, with different quality settings for use by high end desktop computers to HMDs and low performance mobile devices.

The jets' glass material was replaced with a blue transparent Lit material and fine-tuned.

The Reflection Probe component was added to the ground object with again Lit material, fine-tuned appropriately to achieve the desired environment (skybox) reflection effect.

Screenshots attached taken with the High URP asset.
