Additional Changes
Miscellaneous Changes
Changing the layout of shading nodes in a NetworkMaterialCreate group Katana (3.2+) no longer causes a live render edit
- Preset Browser
- The preset browser now exports child materials
- The preset browser can now export materials with shading nodes that use a namePrefix
- Stats are now disabled for live renders. Stats were not valid after live render edits and could cause RenderMan to hang when the live render was cancelled.
Known Limitations
Live Rendering
Changing the cameraName in RenderSettings doesn't update AOVs without a specified camera
Creating a mesh light from existing geometry will duplicate the geometry in-render. Restart the render to remove the duplicate
- Cannot change a geometry primitive type during live rendering (e.g. from NURBS to polymesh)
When assigning a material to a Scene Graph location, that location must be enabled in the live render working set
Live render edits to the visible attribute need group locations to be "included with children" in the Live Render Working Set
Katana Limitation
- The Monitor doesn't support adding/removing displays during a live render
- 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.
