If you are a designer who does a good amount of 3D stuffs, you will need a good rendering software programs.

Fortunately, there are more and more affordable packages. In fact, there are even free alternatives for 3D rendering. These 3D rendering systems are quite useful and handy for design works such as product design, interior visualisation, exhibition as well as jewellery design.

Below listed are some of the free 3D rendering software that can be downloaded off the World Wide Web.

1. Indigo. Indigo is a free, physically-based unbiased rendering engine that employs advanced features such as Metropolis Light Transport, Spectral light calculus, a virtual camera model, physical sky and more.
