Point Light

The point light emits light from its origin in all directions (through 360°), which means it is particularly useful for illuminating certain sections of a design.


The following is how to insert a point light source:

1.Go to the Lighting menu in the Room group, Start tab, and select Point Light.

2.Moving the mouse or entering figures on the keyboard enables you to determine the position of the point light.

3.Clicking again or confirming with the Enter key ends the creation stage.


There are a number of features which can be modified to adjust a point light source. The following image shows a marked point light with its properties.

This is relevant for photorealistic rendering. The larger the source of light, the softer the shadow in the image rendered.

Properties Editor


This is whether shadows should be calculated during the rendering process or not
