Known Limitations
Live Rendering
Creating a mesh light from existing geometry will duplicate the geometry in-render. Restart the render to remove the duplicate.
- Adding a portal light to a dome light doesn't delete the dome light
- Cannot change a geometry primitive type during live rendering (e.g. from NURBS to polymesh)
- Edits to mesh light parameters require that the geometry location is enabled in the live render working set
When assigning a material to a Scene Graph location, that location must be enabled in the live render working set
Cannot create new volumes or enable existing-but-disabled volumes during live rendering.
- The Katana Viewer will crash when muting a light with a light filter reference with "Lock Size to Cone Angle" enabled
Katana Limitation
- When rendering to "it" from Katana, do not stop the render from "it", abort the render from Katana. Your Katana session may freeze for a time if you abort from "it". If you make this mistake you can restore Katana to operation by terminating the prman render process manually. This will be fixed in a future version. You can also avoid this entirely by rendering to the Katana Monitor.
- Light Linking volumes is not currently supported
- 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 updateds will cause interactive motion blur to be disabled. The render must be restarted.
- Support for light arrays of mesh lights is coming in a future version of 22
- Render is not correctly terminated when errorHandler = 'abort', this only aborts traversal, not the render
- PRMan error handlers are not fully supported yet.
- 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.
- There are a few live render limitations in Katana 2.6 that have been resolved in Katana 3.0 based on the improvements to 3.0, typically limitations with live working sets and adding/deleting locations in 2.6
