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.
Kerkythea is a powerful, yet simple to use rendering package that integrates seamlessly into SketchUp and other modeling programs. My experience is only with SketchUp, but the combination of these two packages (I bought SketchUp Pro and use Kerkythea for free!) is the best bang-for-your-buck way that I have found to produce high quality images of 3D models. I have seen some extremely photo-realistic images online, but I am not sure if a paid rendering engine would be able to produce higher quality or be easier to use. If you are looking for a free way to get higher quality images from your SketchUp models I would highly recommend Kerkythea.
Kerkythea seamlessly integrates with SketchUp, eliminating the need for costly and complex 3D modeling software.
Kerkythea has a simple to use interface and does not require extensive training to learn how to use.
Despite being easy to use out of the box, Kerkythea is also very powerful for advanced users. This allowed us to achieve fast results, but also to constantly improve the quality of our rendered images as we have gained knowledge and experience
The Kerkythea plug-in for SketchUp has an incredibly easy to use lighting feature. Spot lights and flood lights can be added, adjusted and manipulated easily, giving a much more professional looking end product.
The user community support for Kerkythea is vast. From tips and tricks to free, downloadable materials packages, there are an incredible number of peer-to-peer assistance options available.
The default viewing mode for Kerkythea is wireframe. This makes it hard to view the model upon opening, however it is easily changed using "View/Adjust/Solid Rendering" in the menu bar. My preference would be for the software to default to Solid Rendering from startup, or to have a way to save the interface settings (If that option exists, I am not aware of it).
When exporting a model to Kerkythea from SketchUp, it usually takes a very long time to open the Kerkythea software. This only happens when selecting "Yes" in the dialog box that asks, "Open exported model in Kerkythea?" The quickest way I've found is to answer "No", open Kerkythea manually and then open the desired file from Kerkythea.
While there are many free, user contributed materials packages available online, it would be nice to have a larger materials library pre-installed in the software.
At this point, I have not found myself limited by using Kerkythea. It is easy to use and has not required a huge amount of time investment to get results. I have been able to utilize 3D modeling software that I am already familiar with and that is also cost effective. The quality of the finished product that can be achieved using Kerkythea is still beyond the abilities that I have, however I continue to learn and grow in my competency as I use the software.
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.
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.
Blender is a free 3D modeling and rendering package. What I liked about Kerkythea is that it integrates with SketchUp, while Blender does not. This allows me to use modeling software that I was already familiar with rather than having to learn something new.
Autodesk 3D Studio Max and Autodesk Maya are also very powerful 3D modeling and rendering packages, however they are not free. They do have free trials, and the software is excellent and powerful. Guaranteed these are both better modeling packages than SketchUp, however with the work I do, SketchUp is easier to use and lower cost. If you're looking at doing more free-form modeling as opposed to basic rectangular buildings like me, you will need different modeling software than SketchUp. While Kerkythea can be used for many model types (*.kzx, *.xml, *.obj and *.sia at the time of this review) from any modeling package, it might be easier to use the rendering features built into 3DS rather than exporting to Kerkythea.
While it is impossible for me to give a firm number, I can definitely say that the images produced by Kerkythea are an excellent selling tool for projects presented to potential clients.
As freeware, Kerkythea has allowed me to achieve quality results without spending a fortune on software. Being self-employed, this is wonderful.
Kerkythea has allowed me to display professional materials without a major cost or time investment in training. This has allowed me to focus on creating floorplans and designs rather than spending all of my time getting the presentation of said designs to look good.
