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 rendering pipeline it's Unity 2017.4LTS
- For LWRP it's Unity 2019.1
- For HDRP it's also Unity 2019.1 but this may be changed with upcoming official HDRP release (Unity 2019.3? ... who knows).
To use "Real Materials" with previous versions of Unity create empty Unity 2017.4LTS/2019.1 project and import a proper "Real Materials" package. Then close Unity and copy "Real Materials" folder from there to your old Unity project. This way was tested on:
- Standard render pipeline Unity 2017.4LTS -> Unity 2017.1.5f1 - materials are fine, demo map causing some warnings about meshes have more than 65536 elements and lightmaps needed to be rebuild.
- LWRP Unity 2019.1 -> Unity 2018.1.9f2 (LWRP was updated to v1.1.11) - materials are somewhat fine, but most of them too dark (because occlusion texture value is ignored, always maxed to "1") and normal maps values also ignored (same, always "1"). Demo map is empty - no prefabs. So, remove occlusion textures from materials and they're good enough to be used.
- HDRP Unity 2019.1 -> Unity 2018.1.9f2 (HDRP was updated to v1.1.11) - materials are fine, demo scene is empty (no lighting & HDRI skybox).
