Thank you for the reply. Happy holidays to you also. You could be surprised at the number of users who implement this asset will orthographic camera, as it really seems suited to backgrounds/UI/starmaps. I think something that would really compliment/enhance this asset is an asteroid belt, and from the despcription I thought it may have been included. It would be great to have a ring of asteroids sprites somewhat similar to what oyu see in IXION -

Asteroid rings are included in the sense of rings around gas giants, sorry if that caused confusion with asteroid belts.
Asteroid belts are a great idea though, they can be implemented with a VFX graph system with a few unique meshes for the asteroids, spawning them procedurally with randomized scales, sizes and rotations. I actually have individual mesh based asteroid generation in a private system, so I will definitely prioritize cleaning it up and publishing it as a system for Procedural Planet Generation.
I just published a large update with improved gas giants and rings (I've renamed them to gas giant rings), streamlined and improved custom lighting and baking workflows, and - orthographic camera support.
Asteroid belts will be next.
