Substance Painter recently got Iray rendering engine by the way. It’s good if you want to easily make great renderings of your models. I personally think SP is one of the best programs I have used. I once tried Quixel, it was unusable.
Let me know if you have any questions about using Substance. Also, you can work with scans directly in our toolset. We are working on a new update to Painter that allows you to edit scans across multiple channels. Check out this video. https://www.youtube.com/watch?v=-_eXE-rxzoI
Ehhhh, using Substance Painter to bake is a much faster and easier way to do things. If you know what your doing.
