We were planning to have a beta version ready for you around now, but we won't make it. We are putting thousands of hours of work into developing Tachyon Render and hope it will become a indispensable tool for your work.
We are very happy with the quality of results we can achieve with Tachyon Render. It turned out to need more work than we anticipated though. We are not completely satisfied with a few aspects like rendering transparent objects so we scrapped the code and decided to do more research on that.
We not only want to make a great tool for you but also to provide a great experience. So we are spending more time on Tachyon Render before a first public release.
I'd like to ask you for a bit more patience. We are working hard to make it worthwhile.
