Known Limitations

Lighting

• Light filters are currently not supported

• Mesh lights currently do not function as expected

• Light filter linking is not available

• PxrEnvDayLight is supported

• PxrAovLight is not supported

• Custom light plugins are not supported 

• Portal lights are not supported

Interactive Rendering

• AOVs and LPEs are not supported
• CropWindows are not available

Batch Rendering

• RenderMan Display drivers are not supported
• If you use ROI and overscan or cropWindow, the ROI will have to be adjusted slightly after a resolution edit to get the correct value during a live render
• Instanced lights with filters using the "Light Filter" coordsys have an incorrect transform. The workaround is to promote the light filter to a shared light filter using a light filter reference.
• We do not receive live render edits from Katana for nodes added at the end of the node graph, right above the Render node.  If a no-op node (e.g. Merge) is inserted above the Render node and the node is added above that then the edit is received.
• Any live updates will cause interactive motion blur to be disabled. The render must be restarted.
