- 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 to see motion blur.

Changes in RenderMan for Katana 25.2
- Fixed bugs with the enable checkboxes in the PrmanStylizedLooks macro:
- Added two switch nodes to fix an error when all display filter checkboxes are disabled. The SNAC node would complain that there were no connections.
- Added an OpResolve node after the display filter network material to fix an issue where the enable checkboxes wouldn't update the live render correctly unless Flush Caches was pressed
