Spot: The spot light is quite similar to the point light with the small difference that you can limit the illuminated area to a small region, the spot.

It emits light into all directions like a light bulb for example.

Point: The point light is probably the most widely used light source.

The distant light object can be used nicely to light outdoor scenes which are in nature illuminated by the sun. Due to the fact that the sun is far away from the earth, the light emitted by the sun can be assumed as being parallel on the earth.

Distant: The distant light emits parallel light rays.

Due to the fact that some pixels in the scene are just partially illuminated by the area light the area light creates soft shadows at these pixels and not hard shadows like the point light.

Area: The area light simulates a rectangular light source.

If a light has an ambient term, the parts of an object facing away from the light source will also be illuminated. Ambient: Add an ambient term to the scene using this property.Light type: There are various light type available in Cheetah3D.If you plan to animate your light source the "-Z" direction is probably the best. Axis: The direction in which the light source casts.The renderer works with all light sources. You can add as many light sources to your scene as you want but only the first 8 lights in the scene will be used in the 3D preview. However, if you want to create your own lighting environment you have to use light objects. The camera light should be sufficient for most modelling jobs. This camera light will not appear in the object browser.

The camera light is a point light with constant attenuation at the position of the camera. Every new Cheetah3D document already has one default light source: The camera light.
