This version is free for all commercial and personal use and does not expire. This version has a maximum rendered image size of 640 x 480 making it a great compliment to the free version of SketchUp, and useful for online or quick conceptual uses.
This does not replace the 30-Day free trial of the full IDX Renditioner which supports 16 megapixel images, and high performance from multithreading. That version will still be available for evaluation.
