Known Limitations
Live Rendering
- Updates to attributes will cause interactive motion blur to fail to render. The render must be restarted.
Creating a mesh light from existing geometry will duplicate the geometry in-render. Restart the render to remove the duplicate.
- Monitor performance can lag behind edits for large scenes
- Creating a mesh light from existing geometry will duplicate the geometry in-render. Restart the render to remove the duplicate.
- Volume edits will break the volume render.
- Adding a portal light to a dome light doesn't delete the dome light
- Cannot Live Render from Viewer camera
- Cannot change a geometry primitive type during live rendering (e.g. from NURBS to polymesh)
- When traversal is parallel, edits to a live material will affect only a subset of assigned geometry unless all of the assigned geometry starts out live or is made live at least once during the live render session.

Katana Limitation
- When a Prune node is added at the end of the node graph, right above the Render node, we do not receive an edit from Katana. If a no-op node (e.g. Merge) is inserted above the Render node and the Prune is added above that then the delete edit is received and the Prune works properly.
