Softimage recognizes any effects (*.cgfx and *.fx) files that are located in the user, workgroup, or factory locations under
the Application/cgfx or Application/hlsl folders. Textures should be placed in Application/fxtextures. If these folders do
not altready exist in these locations, then you can create them.
Put your effects files in one of the following locations:
is the location for your personal customizations.
Place your .cgfx files in C:\users\username\Autodesk\Softimage_2011\Application\cgfx on Windows or ~/Autodesk/Softimage_2011/Application/cgfx
Place your .fx files in C:\users\username\Autodesk\Softimage_2011\Application\hlsl on Windows.
Place your textures in the Application/fxtextures folder of your user location.
is the location for customizations that are shared among a group of users working on the same local area network. For information
about setting a workgroup, see Creating and Using Workgroups [Customization].
(Factory) is the location for presets and sample customizations that ship with Autodesk Softimage. It is located in the directory
where the Softimage program files are installed. Although a recognized location by Softimage, it is not recommended that you
store your own customizations here.
Open Softimage and the render tree. If your effects files contain no category strings (see Categorizing Effects Shaders in the Preset Manager), they will be displayed in the preset manager in the default Realtime > HLSL or Realtime > CgFX categories.
Drag an effects shader into the render tree workspace.
If the effects file is valid and the shader compiles, it displays as a realtime blue node ready to be connected.
If the effects file is not valid and the shader fails to compile, it displays as a red node to indicate that it is in an error
To fix any problems, you can edit the shader in the shader code editor.
To load and edit your effects file in the shader code editor, choose from the main menu (or you can use any text editor for that matter).
If you are working in the render tree, right-click the node and select to open the shader code editor.
Once you have finished editing the effects file in the shader code editor, click to check your code and then your changes. To update the preset manager you may have to restart Softimage.
