Development Progress

YafaRay4tS exporter is currently in beta but is stable for production use and has adequate functionality implemented to be quite usable for real world rendering projects.

The current release added animation support, including the ability to spawn a sequential image batch render process. This allows the user to continue to work inside trueSpace while lengthy animation renders occur in the background.

A major development which I'm sure YafaRay4tS users will appreciate is that help documentation is now available.
