1: Place the files in the "plug-ins""scripts""icons" folders to the proper folders in your local Maya directory. That would be where ever your local Maya user settings are kept in. They will be different on MAYA / OS version that you are running. Typically they are.
" Plug-ins " ~\alias\maya6.0\bin\plug-ins\
" Scripts " ~\Documents and Settings\"username"\My Documents\maya\scripts\
" Icons " ~\Documents and Settings\"username"\My Documents\maya\6.0\prefs\icons\
2: Now that all the files are setup, start Maya and use the Plugin Manager to load the plugin. "Window > Settings/Preferences > Plug-In Manager" click on the "loaded" check box next to the DT3Dskin.mll. This places a DT3D skin Shader in Maya's Visor/Hypershade.
1: Take the files found in the "mentalRay" folder. Place the files in the "icons" "include" "lib" "scripts" folders to the proper folders in your local Maya directory. That would be where ever your local Maya user settings are kept in and where the Installation was made for your Maya. They will be different on MAYA / OS version that you are running. Typically they are.
" Include " ~\alias\maya6.0\mentalray\include\
" Lib " ~\alias\maya6.0\mentalray\lib\
" Scripts " ~\Documents and Settings\"username"\My Documents\maya\scripts\
" Icons " ~\Documents and Settings\"username"\My Documents\maya\6.0\prefs\icons\
2: Now that all the files are setup, one has to edit the "maya.rayrc" file in order for Maya to load the shader. The file will be in your Maya/Mental ray directory typically its.
" Rayrc-File " ~\alias\maya6.0\mentalray\
Once the file is found and opened for editing you must add two lines to the file in its proper locations.
link "{MAYABASE}/lib/dt3d_DT3Dskin.{DSO}"
mi "{MAYABASE}/include/dt3d_DT3Dskin.mi"
3: Now that all the files are setup, start Maya and use the Hypershade under the mental ray tab. There will be a DT3D skin Shader in the Materials section.
4: (optional) This is for Maya 5.0 - 7.0 users in the "extras" folder copy the "attrPresets" folder into your local Maya users presets folder. This should be something like this.
" Presets " ~\Documents and Settings\"username"\My Documents\maya\6.0\prefs\presets\
These are just a few presets for the skin shader for you to work with.
