What's new in this version:
- Expanding the robust feature set of LightWave 2015, this new update offers numerous fixes and improvements, system updates for Python and support for NVIDIA Optimus technology.
- Pipeline updates in the LightWave 2015 Update 3 include improved GoZ and After Effects support; workflow enhancements to the VPR, viewport, and restore options. Interchange enhancements include support for AE CC2015, improved FBX rigging import from Maya, additional support for UV interchange with Unity and other game engines, improved Subd mesh interchange for Alembic, and additional GoZ interchange support for ZBrush 4R7. Hefty scripting improvements have also been made to the LScript Scene Object Agent, with 22 new data members and supporting environment constants, as well as updated Python control over LightWave Custom Object access
