arViewportRender – MtoA Viewport Render Region
arViewportRender gives artists who work in lighting the ability to work with Maya renderings in a more artistic and practical way. Film productions have been tested and advanced forecasts have been fantastic.
Unfortunately, it is only for Maya using Solidangles Arnold rendering.
