The Preset Browser is only available in Autodesk Maya 2016 and h= igher.
You can open the Preset Browser using th= e shelf button or the RenderMan menu.
Presets include categories for light rig= s, environment lights, and materials.
Saving/Exporting a material is easy!
When an asset is saved to disk, all its dependencies are saved to disk t= oo.
These include :
These dependencies can increase the size of a preset on disk and you sho= uld bear that in mind if you want to distribute them over the internet.
RenderManAssets have been designed to be easily transferable from one ap= plication (like Maya) to another (Katana, Houdini, Cinema4D, Blender, etc) = and vice-versa.
Still, it is possible to run into compatibility issues if your material = contains native Maya nodes. RenderMan for Maya automatically converts a num= ber of native Maya nodes which won't be available in other applications, e.= g. the file node or Maya's Cloud pattern. To mitigate these problems, = each RenderManAsset maintains a list of used nodes and use it to evaluate t= he preset's compatibility with the current host application and display a w= arning if it is not compatible.
The system will check :
If you want to ensure cross-application compatibility, avoid non-Pixar BxDFs and Patterns.
RenderMan ships with a standard library that can be found in :
We recommend that you copy the standard library to a location of your ch= oice and leave the default library untouched as a backup. The new copy shou= ld be readable and writable. The asset browser will not allow you to create= new assets if it points to a non-writable location.
The location of the asset library can be set through an environment vari= able or a Maya preference.
The path to the asset library can be set through Maya's preference dialo= g :
You can shift-click the preset browser's shelf icon to directly open the= library selection dialog !
The location of the asset library can be set through the RMAN=
_ASSET_LIBRARY
environment variable.
We only support a single library, so you cannot pass a colon-delimited l= ist of paths to RMAN_ASSET_LIBRARY.
It can be set using different methods :
Maya.env is a configuration file read by Maya at startup to conf= igure a number of environment variables. If this file doesn't exist, you ca= n create a new one in one of the standard locations. This method wo= rks on all platforms : Linux, OSX, and Windows.
Type the following line at the end of Maya.env and Maya should find the = standard library the next time it starts up :
RMAN_AS= SET_LIBRARY =3D $RMANTREE/lib/RenderManAssetLibrary
RMAN_AS= SET_LIBRARY =3D %RMANTREE%/lib/RenderManAssetLibrary
On all Posix platforms (Linux & OSX), you can either define the envi=
ronment variable in the shell you will launch Maya from or append it to you=
r shell configuration file (.cshrc
for csh/tcsh, .bashrc
for bash).
setenv = RMAN_ASSET_LIBRARY $RMANTREE/lib/RenderManAssetLibrary
export = RMAN_ASSET_LIBRARY=3D$RMANTREE/lib/RenderManAssetLibrary
Right-click My Computer and choose P= roperties (or double-click System in the control panel), then click the Adv= anced tab, and click Environment Variables.
