EDIT: (7 May 2025) Hi, thank you again for all the feedback, i have now addressed the various points of the review in the new ORION v2.0.0 update, please note that the URP is now the major focus since is the Unity new standard pipeline, which is why took a bit more to address the HDRP related items. - Added the new planet GPU based system for HDRP (and URP - BiRP) version, so can now use a much more powerful and feature rich procedural LODs planet system, with advanced terrain formations using a noise and heightmap combining graph and advanced shading. (Video - https://www.youtube.com/watch?v=KI5H5hKeo0A) - Added a basic clouds layer using the Nebula clouds, for more advanced clouds can use also Sky Master HDRP and have added multiple prefabs and demos ready for use for this case as well. - Added more examples using the black hole and prefab in HDRP prefab manager. - Added new asteroids setup with more realistic rotation and look. - Added new sun prefab with better dynamic sun corona. About the multiple suns, this will be in works for the next update as is more complex to handle properly. I work on various options on this, including direct skybox integration of multiple suns and more options. Best, Nasos (ARTnGAME) Hi, Thank you for all the feedback, all points will be addressed in the next updates. A fully featured asteroid system with instancing and LODs is in the works as shown below, also a subsystem to create both the rocks and LOD meshes. https://youtu.be/m9MX9-UD8KQ The latest development in planet generation that is the best quality and speed is still under development, so not yet included in the asset directly, but can be accessed currently in the Sky Master ULTIMATE URP Beta 26, let me know the invoice in a personal message and will send the Beta asap to try. This is the result of the new system for reference https://www.youtube.com/watch?v=NiTCa3ih-i8 https://www.youtube.com/watch?v=i0_haL80YBA https://www.youtube.com/watch?v=HENQiRFik98 https://www.youtube.com/watch?v=zXAsbjKPev8 https://www.youtube.com/watch?v=4vGYuWyRpuk https://www.youtube.com/watch?v=m9MX9-UD8KQ https://www.youtube.com/watch?v=OMI0JjUogGE https://www.youtube.com/watch?v=tFfLy9oGie0 https://www.youtube.com/watch?v=v2SaKDck3Kc https://www.youtube.com/watch?v=_ykfMAJco6w All videos are recorded in my 4050RTX GPU laptop. Also the system supports multiple planets, the system is developed on my Sky Master project so it has also directly adapted the clouds system for easier setup. It also supports instanced grass on the planet surface https://www.youtube.com/watch?v=gccjbbYAPNY and also multiple ways to define the surface detail, including a node editor to combine effects and noises, plus compute based programmed noises and heightmap based shaping. Note that all work so far on this new system is done in URP and BiRP due to maximized performance overall as URP is so much faster than HDRP, though is easy to port to HDRP as well. Let me know if HDRP is needed and will work on HDRP demos as well. Best, Nasos

Hi, Thanks a lot for the great review, is very appreciated ! I have now finished four major extras that will go in the next version 1. The new procedural planet system, that is used with Sky Master ULTIMATE clouds https://www.youtube.com/watch?v=IKUO4c6nzA0 https://www.youtube.com/watch?v=wjvZWbbY-SU 2. Real fully volumetric atmosphere system for URP and RenderGraph https://www.youtube.com/watch?v=HFnzqtAiClk https://www.youtube.com/watch?v=Te02hIe8QHk 3. Optimized the current procedural planet system and added water updates for planet water https://www.youtube.com/watch?v=WFSMchkqyL4 https://www.youtube.com/watch?v=d8c0Ksul_Bs 4. Asteroid system with LODs and instancing for maximum performance https://www.youtube.com/watch?v=Hb_aQgjkbJk Also all the systems now have support for the new Unity 6 and URP RenderGraph! A system that will create very detailed planet textures and a LOD maker for the instancer are also in the works and near final stage of development. Best, Nasos (ARTnGAME)

Hi, Thanks a lot for the great review, it is very appreciated :) Let me know also for any feedback on the project and more ideas for next updates Best, Nasos (ARTnGAME)

Hi, Thank you for the review :) Glad can be of help and always eager to see any feedback on the project and improve on it Best, Nasos (ARTnGAME)

Hi, Thanks a lot for the review, is very appreciated :) Many more features are also planned for the system for next verisons, as well as combination with Sky Master ULTIMATE for various effects in weather and planet clouds. Please let me know also for any feedback and suggestions. Best, Nasos (ARTnGAME)

Hi, Many thanks for the great review, it is very appreciated :) I am now hard at work at combination demos of ORION with Sky Master ULTIMATE planetary clouds. This will be an ongoing work and will be added in the Environment Building Bundle. Here is some of the result of Sky Master volumetric clouds used with ORION and planetary water https://www.youtube.com/watch?v=0ZuuVHwbUjw https://www.youtube.com/watch?v=TEBU2exfm_I https://www.youtube.com/watch?v=ONalEAA3r8Y https://www.youtube.com/watch?v=bvOyw9C1XKI Best, Nasos (ARTnGAME)

Review history: https://i.imgur.com/FDBpgSI.png EDIT 4: (20 August 2025) The URP volumetric nebula Signed Distance Field and local lights system is now also available for BiRP pipeline in ORION v2.1.1, to localize the nebula around scene objects for control of the Nebula shape. Also local lights will illuminate the nebula clouds volume.

Let me know also for any further recommendations and feedback. Best, Nasos (ARTnGAME) EDIT 2: March 2025 Hi, I am constantly working on bringing the top quality clouds and water into the next version of ORION and Sky Master, will create a lot of ready to use prefabs if own both assets and will also contain the very detailed earth sized planets that are available already as Beta for URP pipeline and also will be available for all pipelines. Hopefully can deliver the full package soon as well and at that time may update the review. Here is a sample of the current work: https://www.youtube.com/watch?v=8UrURwI6ZD4 https://www.youtube.com/watch?v=u5xx5TaSCCE https://www.youtube.com/watch?v=W7Rc_Jb1sxk https://www.youtube.com/watch?v=LJIz_a4vHNs https://www.youtube.com/watch?v=uRtq9pSNOCE https://www.youtube.com/watch?v=wPAPSxbx8-I https://www.youtube.com/watch?v=8NvGZtBdA9o https://www.youtube.com/watch?v=mdtmTyPpQdk Best, Nasos (ARTnGAME) EDIT 1: Hi, Indeed the combination of the ORION and Sky Master ULTIMATE systems is on the plans. Due to the complexity of both systems and the many possibilities I take this one step at a time and will offer combined demos as development progresses. Sky Master ULTIMATE URP is still in Beta phase, so its systems are evolving and more automations are added, which will help further when the full set of combination demos arrives and will be accompanied by tutorials that will be based on those finalized systems. There is currently demos included in ORION and Sky Master ULTIMATE URP, combining Sky Master ULTIMATE URP Volumetric Planetary clouds with ORION Planetary water system.

Other examples of combined demos I am working on can be previewed below, involving various of ARTnGAME systems. Those demos that contain multiple assets are planned to be distributed in Environment Building Bundle, or be sent on demand as needed.

Best, Nasos (ARTnGAME) Hi, Thanks a lot for the review, it is very appreciated. I am now working on many more upgrades to the system, including further integration of the new water system with Sky Master ULTIMATE weather, big updates on the randomized planet generators and much more. Also let me know for any feedback and suggestions on the system, for further improvements. Best, Nasos (ARTnGAME)

Hi, Thanks for the great review, I am also working on expending further the system, in next update will be adding the first version of the round planets water system and few more features. Let me know also for any suggestions on possible additions on the system. Best, Nasos (ARTnGAME)

Hi, Thanks a lot for the review. Best, Nasos (ARTnGAME)

Hi, Thanks a lot for the review and kind comments. I am also working around the clock for the first big upgrade to the system, that will also include the new Fully Volumetric Nebula module. Here is a sample of the new effect https://www.youtube.com/watch?v=6T5evkGZ9bY https://www.youtube.com/watch?v=uh3fM5_W1cw Also let me know for any further suggestions on improving the system.
