Redshift Real Time

Redshift Real Time is currently in beta and only in Windows with an Nvidia RTX GPU.

Due to the current limitations of Redshift Real Time, it is recommended that RS RT be used with new scenes as you are likely to find incompatibility with many shader networks found in pre-existing scenes.

macOS is not currently supported.

Redshift Production Interactive


Redshift Real Time (RT) is the fastest interactive rendering engine available in Redshift, offering near real time updates. The speed and interactivity of Redshift RT makes it an excellent option for look development, scene layout, and light placement. Additionally, Redshift RT is designed to match Redshift's Production rendering engine as closely as possible, making it ideal for quickly switching back and forth between the two to make the most of each engine's strengths. 

Using Redshift RT

Redshift RT can be enabled directly from the Redshift Render View or from the render settings menu as pictured in the images below.

The option to switch the rendering engine from Production to Real Time in the render settings can be found at the top of the Basic Settings section or in the Globals tab of the Advanced Settings.

Quality Settings

When using Redshift RT the only settings that affect render quality are the number of Progressive Passes and the global Trace Depth limits. Redshift RT has a maximum trace depth limit of 4.

Progressive Passes: 1 64
