Debug Views

You can view debug information from each RenderNode. This information can be useful while setting up and playing back your project.

There is an overlay UI for this debug information that can be controlled directly on each RenderNode. Alternatively, access it in the Nuke Stage Editor from the Render Debug Panel. Full controls can be found at Render Debug Controls.

Note:   Future builds will show more of this information in the Editor as this product is developed. Some of these views are technical - if you are continuing to encounter errors, you can contact support.

Tip:  You can hide or show the Render debug menu bar by using the keyboard shortcut F1 in the Render application. Alternatively, in Nuke Stage Editor go to the Render Debug panel (found in the Setup workspace by default) and tick/ untick Show menu bar.

Below is a description of the tabs in the Debug Views.

Barrier Wait

This graph details the amount of time spent waiting on the sync barrier every frame.

This is an advanced view which indicates how long the process waited for the relay to signal it to start rendering the frame. If the graph grows constantly or has large spikes it might indicate performance and/or sync issues.

Camera

Shows a 3D view of the camera and display attached to the RenderNode.

A live camera view is also available in the Nuke Stage Editor but this view can be useful for ensuring the tracking data is being received correctly by particular RenderNodes.

Frame Summary

Provides a high level summary of the frame, including framerate and timecode.

Most high level information for each RenderNode is available in the network panel in the Nuke Stage Editor, but it may be useful to occasionally double check data here.

Image Loading

Provides some detailed visualizations on the performance of image loading, particularly B44 EXR sequences that may be playing back.

This is an advanced view, but it can be helpful to get detailed performance stats when general playback performance on a RenderNode is poor.

Profiler

This tab displays a flamegraph for RenderNode performance. Individual frames can be selected to give more information on where the RenderNode is spending time.

This is a useful view which can tell you if each RenderNode is consistently hitting its target speed, and if not where the time is being spent.

Note:  The profiler auto-freezes when a frame is selected, and will continue to be frozen until you click the button to unfreeze the overlay.

Tip:  To stop the overlay from updating, press Space or click the button at the top of the view. You can then investigate a particular frame.

Sync

Displays a configurable strobe that can be used as a visual guide as to whether machines are syncing. In synced RenderNode setups, the strobe color should always match across RenderNodes.

This is the quickest way to ensure a multi-RenderNode setup is synced. The strobe color and speed can be customized.

Warning:  This feature content contains imagery with flashing lights and strobe effects that may trigger seizures or cause discomfort in individuals with photo-sensitivity. User discretion is advised.

Textures

A view of all textures being processed by a RenderNode.

This information is also viewable in the Nuke Stage Editor image viewer, but it can be useful to ensure each RenderNode is also processing the images correctly. Missing content here may indicate missing assets on a RenderNode machine.
