The system is now compatible with Unity 6 URP RenderGraph in Unity 6 LTS in the latest Sky Master ULTIMATE RC 27. It includes industry level optimized Volumetric Clouds, Volumetric Lighting, an Ocean system, GI Proxy and optimized SEGI for real time Global Illumination and a physically based Sky Rendering system with atmospheric scattering.

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, or through a Personal Message in Unity forum or ARTnGame Discord Channel with the invoice or order number. The pipeline versions are separate standalone projects and the store system installation should be removed before installing the URP or HDPR packages.

The Sky Manager provides automatic or on demand day/night cycle & smooth weather transitions.

Windows Demos (Use Fantastic quality):
InfiniCLOUD (Vegetation created & optimized with InfiniGRASS v2.0)
Atoll Light Scatter
GI Proxy Volume Lighting | Airplane
Dark Mood Dynamic Particle Clouds
Fall through clouds

The skybox mode offers complete integration with Unity and all its features (IBL, GI, Skybox).

Advanced particle effects like global/local Turbulence & Attractors, Particle sticking- propagation-spreading & particle to particle collisions (ideal for ice/fire simulation), Tornadoes, Volumetric Fog/Smoke, volcanic eruption & lava flow, rain, chain lightning & more are also included.

Create spectacular skies, dynamic clouds and weather systems, with time of day and seasonal changes. Use indirect lighting with Global Illumination Proxy system.

The system has been created to deliver realistic Skies & Weather effects, with seasons and dynamic clouds, scalable depending on the hardware target. Sky Master works on all platforms (most modules of v3.2 are mobile ready*, some modules like the volumetric fog are Desktop only. The mobile version of all features will be integrated in the configurator in v3.3 of the asset).

The new in v3.0 Ocean system provides a complete water solution, with shore lines, underwater, multiple wave options and fast speeds.

*For details on mobile platform support for the various Sky Master v3.0 modules and demos for testing on Android, please contact me in the support email or the forum thread.

ARTnGame Asset Upgrades Guide

The URP and HDRP complete remakes of the system are available to all users on PM request in Sky Master Unity forum thread.

The URP and HDRP versions are being developed on and guaranteed to work in Unity 2019 (2019.4.22f and above) and Unity 2021.3 LTS (2021.3.0f and above, including Unity 6000.0.22f1).

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, 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.

Sky Master ULTIMATE asset is for Standard Pipeline and users of the system can enter the testing phase of the upcoming Sky Master ULTIMATE URP and Sky Master ULTIMATE HDRP assets, each remade from ground up for the specific pipeline.

Currently Sky Master ULTIMATE UPR Version 26 and HDRP Version 16 are available to all Sky Master ULTIMATE asset (Standard Pipeline system) users for download in Google Drive (October 2024 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.
