Twilight Render is a rendering software. It's a "plug-in" to Sketchup software. The Administration treats their customers brutishly. They don't offer support. And, has accused numerous customers of using pirated software. Myself being one of those customers. I use legally downloaded software from their website. I have sent numerous e-mails to Administration, but they don't answer incoming e-mail. They don't have any telephone contact. And their physical address is unknown. I strongly suspect the legality of the persons operating the Twilight Render website...and their web-page on Facebook. If you're a graphics person, don't use Twilight Render software. Save yourself a lot of headaches.
