V-Ray, free and safe download. V-Ray is 3D model rendering software, usable with many different modelling programs but particula. Autodesk 3ds Max.

Interfacing With The 3D World V-Ray was in use more than a decade ago as of this writing, making it an extremely mature application that's compatible with just about anything. Unfortunately, it also shows its age a bit in the interface which, despite streamlining in recent versions, is still dull, with lots of large and sometimes disorganized square panes full of small text. On the other hand, the program is very stable, never crashing in our testing, and some of its tools have clearly been perfected over the years to maximize usability: the sectioning tool, for example, makes it very easy to modify large sections of your render that need to be moved or removed.
