RT Refinement

Refining a raytraced scene is a great way to see how your final project will look.

Refining a scene should only be used on raytraced scenes that are static frames. Refinement of a scene will not work in real-time due to the time it takes to refine each scene frame.

By default, refining is on in Notch, refine is set to a default of 1000 refine steps in any scene. The refine steps counter and time elapsed can be seen in a panel at the bottom of the node graph.

The RT refinement node is to control the number of steps the scene needs to refine.
In addition to this, there are Nvidia and Intel AI denoisers. These denoisers will reduce down the number of refinements steps needed on a scene.

In the RT refinement node properties, under attributes, set the Max Refine Steps to the required number of refinement steps needed.
10000 steps is the default setting.

Refining of the scene can be turned on and off by clicking on the new refine render button in the GUI.

With no RT Real-Time Denoiser or RT Refinement present and active in the scene, the default behaviour is Refining with default settings.

RT Real-Time Denoiser

RT Real-Time Denoiser is the solution for realtime playback.

This will blur the noise out of your scene. Using method such as temporal denoising.

The denoiser node comes with preloaded presets that can be set in the preset properties bar.
