The Octane QT5 IPRProvides artists a quick preview of the image prior to the final render, and efficiently allows for adjusting some elements in the scene such as lights, shaders and textures interactively. An IPR image contains shading and lighting data including some for visibility, in addition to the software render. window provides more functionality and a more modern interface than the original raw OpenGL IPR window. The QT5 IPR window can be selected from the Octane Plugin Options window under the IPR tab (figure 1).
