Solid Angle releases Arnold for Houdini

HtoA provides a tight integration with Houdini, in a way that is familiar to both Houdini users and Arnold users in Maya or Softimage. It also enables smooth lighting workflows between Houdini and other DCC applications, since setups can be exported and shared.


The Arnold for Houdini plug-in comes with the latest – and fastest – version of the Arnold core (version 4.2.1) and is provided free of charge to all customers on current Maintenance & Support.
