The use of a point light is ineffective. Arnold simply creates a black screen. I adjusted the intensity to 200, but nothing happens. Light that is directed in a specific direction is effective.
In Arnold, the global illumination is controlled by the Ray Depth parameter. In the Arnold Renderer tab of the Render Setup dialogue, under the Sampling and Ray Depth section, we have Ray Depth, where we can see values for the diffuse, specular, transmission, and volume components of the rendering.
You can choose between a Box, Sphere, Cylinder, or Cone for the light. A little sphere is included in each form to represent the actual light source (provided the Volume Light Direction is set to to Outward or Down Axis). Volume Lights are similar to three-dimensional Area Lights in appearance.
Arnold interior light is a computer program for rendering three-dimensional, computer-generated scenes using unbiased, physically-based, Monte Carlo path tracing techniques, to bring light in the scene, it makes the scene sims natural
