Interior mode

Banding can occur on still-images in Interior Mode, when rendered with Network Rendering.

Expand
titleDetails and possible solution

Region mismatches (brighter/darker) can happen when using Interior Mode for Network Rendering, especially for lower resolutions.

Possible solution: Try to increase the resolution of the image.


The Global Illumination sampling for Interior Mode has been improved for KeyShot 8 and may cause scenes to be brighter than KeyShot 7.

titleDetails and possible solution

The Real-Time View uses a slightly different approach from the Output window when rendering, this is especially apparent when dealing with caustics with Interior Mode.

Possible solution: Try to increase the amount of samples.


Volumetric Caustics (for example, on Cloudy Plastics and in Scattering Media) are only supported in Interior Mode.
