From ARCHICAD 18 the Lightworks rendering engine has been replaced to Cinema 4D rendering engine. This post is about creating new Lamp and Light objects working with the new rendering engine.
Process of Light object creation
- Create the geometry of the lamp with the 2D and 3D commands, in which the light source should be placed
- The new object should be under the Light subtype, otherwise the light handling controls would not work
- Depending on the requirement you can chose between two options:
- If similar features as in the Lamp objects in ARCHICAD Library fulfills the requirement, the light sources can be created by calling the “lightMacro_m” from the ARCHICAD Library. For an overview of the Light sources used in ARCHICAD Library check the Light sources and objects in ARCHICAD Library post.
- New Light source can be created by using the LIGHT command with all the functions the Cinema 4D rendering engine. This method requires rendering light handling knowledge and well-known parametrisation of the LIGHT command. Its advantage is that all of the functions of the Cinema 4D engine can be used. For more information about this method check the Cinema 4D Documentation.
Light object creation with existing macros
The Light and Lamp objects in ARCHICAD Library use the “lightMacro_m”, which contains the parametrisation of the LIGHT command for basic light sources. In the macro call the lightgroup type should be defined by giving value for the “iLightGroupType” Integer parameter. These lightgroup type values have named variables in the “lightMacro_m”:
- 1 – LIGHTGROUP_GENERAL_LIGHT: Creates a General Light Source. The basic light source can be defined in the iC4dGenType parameter. For more information about the General Light Sources and basic light sources in ARCHICAD Library check the Light sources and objects in ARCHICAD Library post.
- 2 – LIGHTGROUP_BUILTIN_OMNI: Creates a light source based on Omni light source type.
- 3 – LIGHTGROUP_BUILTIN_SPOT: Creates a light source based on Spot light source type.
- 4 – LIGHTGROUP_BUILTIN_VIS_AREA: Creates a realistic surface for the illuminator based on Area light source type.
- 5 – LIGHTGROUP_BUILTIN_NONVIS_AREA: Creates a non-visible light source based on Area light source type.
- 6 – LIGHTGROUP_BUILTIN_FALLOFF: Creates the three-dimensional light cone.
Lamp object examples with “lightMacro_m” macro call
In the following examples no further effects have been used for the example picture renderings.

Basically one light source is used in the Lamp objects. However the surface of a closed lamp-shell around a light source can be simulated with a luminous surface. For this effect a visible Area light source can be used as an additional light source:
