Corel Painter does have a lot of great brushes, and they do emulate real art supplies very well. Especially the thick paint is well done. But unfortunately there are so many functional and UX bugs that overall it is just horrible to work with. When contacting customer support about it, they really seem clueless about the seriousness of the situation, and clueless about what proper UX is in general. They have tried to make it work a bit like Photoshop, which is a good move but then some things are absolutely not intuitive at all and they are definitely missing the mark horribly with so many issues. I would highly recommend using Photoshop instead, though you'll have to download them separately; it also offers a lot of great brushes nowadays and works much much smoother without all those aggravating bugs of Painter. The price of Corel Painter is just not at all worth all these horrible bugs.
KeyShot can do some really amazing things as far as product renderings. You can turn simple 3D models into realistic images in a very short amount of time. I wish there were a way to manipulate the geometry once imported into KeyShot. The software allows this user to move geometry but not change its shape or form.
Keyshot has a simple and intuitive interface that makes it easy to use for quick renderings.
Through Keyshot's viewport, you can see real-time changes when replacing or adding textures to a 3D model.
The new Keyshot 8 comes with volumetric features such as fog that can add depth to your image making process without having to manually do it later in another program.
If it wasn't quite clear yet, I'll state it again: the usability of Corel Painter is, simply put, horrid. And I am not talking about rendering, lagging, etc., it is not even all that bad there. I am talking about the weird issues like being unable to move a brush into a custom brush palette when you work on a second screen, like being unable to move the software onto the second screen in the first place unless you separate all the palettes and the windows (and if nobody tells you upfront there is no way of knowing because the manual doesn't state this at all), and then having to drag all your separate windows and palettes over one by one every time your computer wakes up again, and they won't really want to move to the other screen but only through a tiny corner of your screen, and the fact that you have to scroll through lists and lists of fonts but can't search and when you apply this font, add another piece of text the font jumps back to the default font of all the text already applied even when you haven't selected any of the text. Just to name a very small few.
It was really hard to get them to understand what I was having problems with. It was hard to get the message through that Painter has an unacceptable amount of functional and UX bugs. When I finally talked to someone who was easier to communicate with, he was very stoic about the situation, like they didn't really care about the awful amount of bugs.
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
Corel Painter has support to multiple OS and across all the devices. Coloring and multi layer imaging works very well. The new enhanced brush settings and the redesigned brush libraries.
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.
