Rendering preferences

The RENDERPRESETS command allows you to create and edit render presets, and to set the current render preset through a dialog box.

Setting the render preferences

  1. Open the Settings dialog box.
  2. Under Program Options, expand the Rendering settings category.

Current material:

Specifies the material for new entities. By default, the Global material is used.

Lighting units:

  • 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 may 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 illumination 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.

Tile mode light synch:

Controls the synchronization of lighting in all model space viewports. (Internal use only)
