supporting the Gelato software products .With the release of Gelato 2.0, and in a push to popularize GPU accelerated rendering (as opposed to the traditional CPU rendering), Nvidia
released a free version of Gelato for PCs. Some of the more advanced features on this version were locked out, such as those used for production rendering. This was done to encourage more
professional users to purchase the full product. However, Nvidia has recently released Gelato Pro as a free download without any additional license. It does not come with support from Nvidia, but there are user forums.
