Just a sneakpeek on something I've been working on. I managed to mod shaders into SFM. Sadly my computer started to lag heavily but I was running everything on max and had several shadows rendered.
This is a vast step up from normal shading in SFM. You can check the attached image for a comparison.
There are more shading techniques but I might explore that in the future. This is only good for renders. Advanced shaders aren't really needed in animations due to motion blur and post-processing.
