"Developing a software (whether is for rendering or not) always represents big challenges, one if which is how to increase the number of functions, make it more sophisticated while maintaining the same simplicity of use, speed and quality. KeyShot 4 is a brilliant example of how we are getting a lot more capabilities, while the level of simplicity, robustness, quality and speed remains as excellent as we have been getting from Luxion."
- Peter Kossev, Pixel Mathematics, Inc.

"In my opinion [the lighting] is a game changer for me. I will be able to add that extra pop to my images before post. I also used the new ground plane, which is another great feature."
- Tim Feher, CGI Leader, Interactive Marketing, Chrysler Group LLC

"I must say the new light source materials are a fantastic addition (especially IES support!). I've been reworking a scene that I made in KeyShot 3 by adding IES lights and area lights. The quality of the lighting and the speed of rendering seem are improved significantly from the basic emissive material in KeyShot 3 and I absolutely love the reworked translucent material! I feel that now -using surface color, subsurface color and translucency multiplier- I can get the exact look I have in mind within a few minutes and the diffusion of light materials through translucent objects is amazing.”
- Dries Vervoort, Mechanical designer, R&D, Caradon Heating Europe

“Guys, this is VERY COOL!!! So far my favorite are the “area light diffuse.” It helps to create spectacular images. I can gently light specific areas of the object for the perfect look. I also love the render passes. So far, so good, hasn't crashed once. This is really, really GREAT stuff!!!”
- Piotr Kolus, Digital Artist, Ars Thanea
