Materials LibraryIncluded with YafaRay4tS are 5 custom trueSpace Direct3D materials. These materials mirror the YafaRay materials Shiny Diffuse, Glass, Glossy, Coated Glossy, plus one special material (Material Light) used to indicate that an object is to be used as an object light.

YafaRay4tS Glass Material PanelBy using Direct3D materials the user is able to get rudimentary feedback within the trueSpace realtime display as to how the materials will look when rendered. It also allows for the user to use the built-in trueSpace tools for applying and inspecting the material.

The YafaRay material settings have been added to the material panel so that they can be easily edited when viewing the material in trueSpace's material editor. Unfortunately because of the limitations of DirectX9 reflections and refraction cannot be simulated in the realtime viewport. Instead, specular faking and specular mapping are implemented in the DirectX materials to help give the impression of reflective surfaces.

You can visit the help section to get specific breakdowns of the YafaRay4tS panels and settings.
