Of course! I stumbled on your work after googling around to see who makes the best print emulator these days (I'm a digital graphic artist with a penchant for physicality), and I was shocked to find such a refined and robust tool.
That's fantastic; thank you for confirming. If it wouldn't be too much trouble, could you point me in the direction of how to modify the shader in those two ways?
If not, perhaps consider them as feature requests for a future update? ;)
