Vertex Shader

You can configure the vertex shader used by a material here.

1. Lighting
   Enables/disables vertex lighting and hemispherical lighting using the checkboxes.
   If hemispherical lighting is used, a checkbox for the vertex color alpha value is also provided.
2. The vertex color scale can be changed by entering numeric values directly or using the slider window.
3. Shader management
   Select which shader to use from the pull-down menu.
   
4. If there is more than one shader parameter, you can move up and down the selected shader parameters in the list.
5. Add
   Adds a new shader parameter.
   Press Add opens a shader parameter input dialog, where you can set the parameter type to be added and set the vector based on the selected type.
6. Delete
   Deletes the selected shader parameter.
7. Edit
   Allows you to edit the selected shader parameter.
   Pressing Edit opens the shader parameter input dialog, where you can edit shader parameters.
8. This window displays a list of user-defined shader parameters that have been added.

Shader Parameter Input Dialog

This dialog opens if you press the Edit button or Add button for adding user-defined shader parameters.

1. Change name and type
   This item is displayed only when Edit has been pressed. This allows you to edit the name and type of shader parameters already added.
2. Enter the name of the user-defined shader parameter.
3. Select the shader parameter type using the radio buttons.
4. Boolean
   This item can only be set when boolean has been selected as the shader parameter type used by the material.
   Select true or false.
5. Vectors for each dimension can be set under shader parameters if a type other than boolean is set.
   If boolean has been set, this item is grayed out and cannot be selected.
