Real Materials documentation [v3.1 from November 2019]
Here are some useful links:
Important notice: keep track of free disk space using Unity Asset Store and "Real Materials".
- Since two new render pipelines were added (HDRP and Universal) on top of Standard (Build-in) and lack of support of separate downloads for pipeline-specific assets in Asset Store there is a potential place for a problem with free space. Summary all 8 volumes of "Real Materials" series have a size of 25GB (!) because each volume contains 3x of assets (for HDRP, URP and Built-in rendering pipelines) and all those 25GB of assets stored here:
C:\Users\*your Windows user name here*\AppData\Roaming\Unity\Asset Store-5.x\ (for Mac it's here, for Linux it's here)
Each asset you ever downloaded from the Store has a copy in this folder and it's never cleaned up automatically. So, if you have troubles with downloading or unpacking "Real Materials" files in Editor - delete everything from that folder and try again. Hope Unity fix this someday, but for now it's how it is.
Minimal supported Unity version for "Real Materials" series is:
- For Standard (Built-in) rendering pipeline it's Unity 2018.4LTS
- For Universal rendering pipeline (URP, formerly LWRP) it's Unity 2019.3
- For High definition rendering pipeline it's Unity 2019.3.
To use "Real Materials" with previous versions of Unity create empty Unity 2018.4LTS/2019.3 project and import a proper "Real Materials" package. Then close Unity, copy "Real Materials" folder from there to your old Unity project and pray.
