Here is a tip on lighting setup that may help new creators with making their cards and other people in general with more engaging screenshots.
Your computer monitor is a 2D surface which doesn't project depth (Z axis), just like a regular photograph. How do regular 2D photographs transmit that information of depth? With the interplay of light and shadows. Pick any professional photograph or movie, and you will usually see that interplay of shadows and light if they have been properly lit up. It works the same way with a monitor and HS2.
In order to perceive depth on your monitor, you have to position the light source in a way that will create shadows. A good rule of thumb is slightly above the subject and 3/4 off the subject. For that I highly encourage using one of the two post processing modes available in the game: DHH or GraphicsMod.
GraphicsMod usually offers more lighting options, more sources of light and subsurface scattering (SSS) which can be very handy if you want to place rim or hair lights. This mod offers the highest quality in general but at the price of complexity in its setup and major drawbacks on performance. You can use SSS with NGS but you wont be able to harness its benefits unless you know exactly what you are doing with it.
DHH is simpler to setup and understand its inner working, and best of all it doesnt compromise on performance. You can have up to 2 direct sources of light which is plenty 99% of the time, and I find the quality to be good enough for editing and quick dirty screenshots. This is personally my preferred setup.
Once you setup your light correctly, you find out that it becomes much easier to spot areas on the face or body that need attention. For creating 'realistic' looking characters, the parts that need the utter most attention are the nose and jawline. And it is very hard to spot bad areas if your lighting set up isn't on point.
My DHH settings for card editing.
If you change the camera to view your character from the side, you will have to adjust the camera Y rotation.
When facing your character directly, the settings will look like this:
In the examples below, you can see the difference a proper lighting setup can make vs an unoptimized setup under SSS/NGS that produces a totally flat image.
Very handful for editing bodies too as you can better observe what some sliders do.
Good luck everyone. Hope this helps.
