Timing

• file written by “usd_rop” will include material link , but
  • Image sequence doesn’t support, you have to use “padzero” commend to override path attribute after import by “subLayer” node

Component Builder

• file location for component output
  • $OS/chs("name")/chs("filename")``
• Variant name
  • Component geometry > Advanced > Geo Variant Name > “ variant name”
  • Component Geometry Variants > Variant Set > “geo”
• Animated Mesh
  • Component geometry > Attributes > Author time samples > “If SOP is Time Dependent”
  • pipe “cache” node downstream of the componentgeometry node

Tips

1.Material disappear When material disappear on the view port(whatever open GL or Karma Render), First check the “Display material on objects”!

2. Asset update(override) failed Viewport karma will stash USD files in memory, so doing a render without the asset that you want to update then problem solved!
