"I received an email about renewing IRender nXt which says: "new features include" but lists nothing. What, if any, are the new features?"
We add new features and bug fixes almost every month. The most recent new features are:
September 2012
Added a new tool to download Render Ready components from the 3D Warehouse. In the initial version we posted several lights, mirrors,and trees to see how this will work for you.
Added a Restart Rendering button to the toolbar, to quickly restart a rendering, only sending the changes for Materials and Rendering Options.
August 2012
Added a tool to the Options Light tab and toolbar, "Query and Find Lights in Model", to identify, help to locate, and edit all of the lights in a model.
July 2012:
Added a Sample Drawing dialog for new users to download models which demonstrate various rendering solutions
Added "Automatically include all Lighting Channels" check box.
