Model Shaders and Applications Shaders

TurboCAD divides its shaders into two database categories: Model Shaders and Applications Shaders.
DEFINITION
In TurboCAD a shader is a component which is use to define how elements in the drawing are to be rendered. These elements inculde: Materials, Luminances, Environments and Render Styles.
 
Application Shaders manager: This is the shaders database which contains all shaders sets, which are connected with TurboCAD as a whole. Model Shaders manager: This is the shaders database which contains the shaders sets, which are connected with the specific drawings.
Initially, in a new drawing, there are no elements in the Applications Shader database. Elements are added as they are applied or created. Once they are in a drawing they wil be listed in that drawings shaders. Thes can be seen in the drop-down combo boxes will have the following format:
Under Categories:
                                    Active Drawing                                // Materials in the active drawing
                                    Drawing name1                               // "In model" Shaders manager
                                    Drawing name2
                                    ----------------------------------------     
                                    All TC database                              // Equal to "All Categories" in previous TC
                                    Brick
                                    Circuit
                                    ……………………………………….
                                    Wood floor

This means that when Active Drawing is selected (or any other drawing) that only those materials in that drawing will be listed. 

As it is possible to see from the described format, in the first place is always the Shaders manager for the active drawing. After that follow the others "In model" shaders managers (for all opened drawings). Next comes the special non-clickable separator. After that follows the "All TC database", which is equal to "All Categories" in previous TC versions. Finally, at end, the list of all categories of the Application Shaders manager is present.
N.B. Here it is important to note that shaders manager for the active drawing is always present in the combo box in comparison with other drawings shaders managers, which are in the combo box only if they have at least one shaders set.
