Utilizing IBL Effect

The IBL (Image Based Lighting) feature simply uses image map to simulate the ambient light source which gives higher realism but save lighting computing efforts, and also increases the flexibility to create base ambience.

Apply one of the templates from the atmosphere library to see the optimized result of IBL effect.






The Concept of IBL

The image applied for the IBL is mapped onto an invisible sphere and projected from the sphere's surface towards the center of the sphere.

The benefits of IBL are:

  • The ambient color can have various details rather than just one.
  • You can set keys to the IBL sphere, which compensates for the insufficiency of ambient lights.
  • Multiple point light effects can be generated by merely adjusting the source image.
  • If you use a video, the ambient light can be dynamic.
