Thanks.
Haven’t really compared Visualize and Keyshot yet…that’s on my things to do, but I think they should be very similar.
I think you have to do a lot of tweaking to get both softwares to get things just right. From strategically placed emmisive and invisible objects to white/black reflecting panels. Stock environments are OK but often not enough so we have designed custom ones or added additional lights. We often have to split the tube in half and turn off parts/sidewalls of the plane to get enough light in. Lighting the inside of a tube is one of the hardest things to do.
10+ years ago they wanted to be the simple rendering solution for product shots but slowly they are becoming more and more complex. They are still easier than 3D Max but I still remember some of the 3D Max renderings were very or more realistic.
