Starting Multiple Renders

The Start Multiple Renders dialog allows users to start multiple Preview or Live Renders by selecting various combinations of global Graph State Variables (GSV). The ability to start multiple renders at once and have them render simultaneously can greatly improve efficiency as you don't have to wait for one render to finish before starting another. This can be very useful to compare lighting adjustments across multiple shots, or material and asset variations, for example.

Note:  Multiple simultaneous Live Renders are not allowed by default. Starting a new Live Render cancels any currently active Live Render. To enable simultaneous Live Renders, go to Preferences > application > rendering and enable allowConcurrentRenders.

Using the Start Multiple Renders Dialog

To use the Start Multiple Renders dialog:

  1. Click the Shelf Actions button at the top of the Katana UI.
  2. Select (Other) KatanaQueue from the Shelf dropdown.

  3. Select Start Multiple Renders...

    The Start Multiple Renders dialog opens.

  4.  Choose the Render Nodes, Global GSVs, and individual GSV options you want to render.

    All available options are selected by default.

    The total number of renders that result from the current selections of Render nodes and GSVs is shown and updated in a label at the bottom left of the dialog.

  5. Enter the frames you want to render in the Frame Range text field.

    You can enter individual frames, or frame ranges by separating them with commas, for example: 1-10, 20, 30-45.

    You can also use the Presets dropdown to select from Current Frame, Working In/Out Frame and First/Middle/Last Frame of the timeline of the current Katana project.


  6. In the Send To dropdown menu, choose the render farm you want to send the render jobs to or choose Local Machine to use your local machine to perform the renders.
  7. Click Preview Render or Live Render.

    A Preview Render or Live Render dialog appears while the renders are starting.

    The images begin rendering and can be viewed in the Catalog tab, the Monitor tab and the Monitor Layer in the Hydra Viewer.

    Render jobs are displayed in the Katana Queue tab.
