The rendering capability with SolidWorks PhotoWorks is pretty good but takes time to learn and is a little cumbersome compared to KeyShot. KeyShot offers a SolidWorks plug-in that works great allowing the user to export models directly from SolidWorks to KeyShot.
Keyshot is simpler and more intuitive compared to Octane. That being said, Octane is far less expensive and can take advantage of a GPU making it more versatile.
Although both have their pros and cons, Octane is far less expensive and it allows for more control over the geometry within a scene with better lighting and camera controls.
Keyshot is great for quick renders and its ability to make changes for a fast production pipeline. Since I primarily use it for concept art and making environments, it is not the best when handling larger scenes as it will take a toll on the CPU.
I have been able to import an environment and create realistic lighting rather quickly by using the power of GPU rendering. Paired with its ability to create instances of geometry, it makes it easy to render a megacity environment in half the time. One issue with this is the clutter that can be made with connecting nodes.
Octane uses GPU rendering so it takes advantage of the video card.
It gives you a good selection of options to tweak and refine your model rendering.
It can use 3D instances so it doesn't overuse computer resources.
There are plugins that can be incorporated into other 3D packages for rendering.
Octane is particularly inexpensive compared to other 3D render packages.
You are able to copy certain sections of nodes in order to create different iterations of the same environment or model. For example, changing the lighting or camera features.
Honestly, I've only needed customer support a couple of times. One time was a question about licensing which their customer service explained very well and offered just the help I was looking for
