Latest tutorial video on project cleanup if needed and use of the 2 latest prefabs, plus enable of fly through mode and control of cloud bed curvature. The system requires the Unity Post Processing Stack to be installed from the package manager (for BiRP pipeline).

The versions of the URP and HDRP complete remakes of the system are available to all users on request in Sky Master Unity forum thread and a Personal Message in Unity forum or ARTnGame Discord Channel with the invoice or order number. The Beta versions are separate standalone projects and any prior Sky Master installation should be removed before installing the URP or HDPR packages.

The system is working in Multi Pass VR in the Standard Pipeline, it has not been tested in Single Pass modes. Also the URP and HDRP versions have not been fully tested and are not guaranteed to work on VR, some URP modules have been confirmed by users to work on Multi pass VR, but the system in general will not support officially VR going forward.

Not all parts of the system is for every platform, so not all parts are guaranteed to work on Mobile, or WebGL or other special platforms like consoles. Windows is the official fully supported platform where everything is tested and submitted from.

(*) Note that Ethereal core, which includes the complete Ethereal functionality, is included in the Sky Master ULTIMATE URP Beta, currently available through Google Drive download to all Sky Master ULTIMATE users. The Ethereal standalone asset has an extra library of Forest assets and demos and many more demo scenes for reference, so an upgrade path is offered if those extra demos and URP forest assets and foliage shaders are needed.

Currently Sky Master ULTIMATE UPR Version 26 (Unity 2022.3), URP beta 28c (Unity 6 LTS) and HDRP Version 17 are available to all Sky Master ULTIMATE 2021 (Standard Pipeline system) users for download in Google Drive (August 2025 releases). Please provide the invoice or order number in a personal message to be eligible for the Beta phase of the new URP and HDRP upcoming assets. Also the asset must have been downloaded to enter any of the Betas, not need to install it or download whole, only start the downloaded. InfiniGRASS URP Version 2.0 and Oceanis Standard Pipeline Beta v0.3f1 are also available.

All assets offcially support the Unity LTS versions cycle they have been uploaded to store with. Currently Unity 6 new URP Render Graph pipeline is supported through the latest pipeline based releases. Note that the new URP Render Graph pipeline is a totally new and different pipeline than the normal URP, so all effects had to be re-written from scratch for the new platform.
