Setting the render preferences
Open the Settings dialog.
Under Program Options expand the Renderingsettings category.
Current material: Specifies the material for new entities. By default the Global material is used.
0: No lighting units are used. Enables generic lighting.
1: Enables American lighting units: Foot-Candles.
2: Enables International lighting units: Lux.
Web lights can be created only if the LIGHTINGUNITS system variable is set to 1 or 2.
Default lighting: A distant light that follows the view direction. This setting can be different per viewport.
0: Default lighting is used if no lights are switched ON.
1: Default lighting is used instead of the light sources defined in the drawing.
Linear contrast: Specifies the ambient light intensity. Values between -10 and 10 are accepted. A value of -10 results in maximum ambient light. A value of 10 results in no ambient light.
Linear brightness: Specifies a scaling factor for the light intensity. Values between -10 and 10 are accepted. The default value is 0 (no scaling). Negative values decrease the light intensity, positive values increase the light intensity. This setting can be different per viewport.
Render using hardware: Choose User software only (slower) if hardware rendering fails. It might be necessary to restart BricsCAD after changing the setting.
Real world scale: Controls the rendering of materials with units set to real-world scale
Sky status: Specifies whether sky illuminiation is computed at render time. (Not implemented yet)
Texture map path: Defines the search path for texture map images. In the BricsCAD program folder exist three subfolders under Textures, each containing a number of texture files of the same name. Images in folder 1 have a size of 256 x 256 pixels, folder 2 contains images of 512 x 512 pixels, images in folder 3 have a size of 1024 x 1024 pixels. If the Diffuse map setting of a material uses the image name only (not path), you can control the quality of a rendered image by setting the TextureMapPath user preference to folder 1, 2 or 3.
Render material directory path: Specifies the path of the folder where the render materials for the Material Browser are installed.
Render material static directory path: Specifies the path of the folder which contains read-only resources for predefined materials, such as their previews.
Tile mode light synch: Controls the synchronization of lighting in all model space viewports. (Internal use only)
