Heyyy, I haven't seen anyone do a tutorial for this before, sooo I put one together. This is for MMD/MikuMikuDance and for making the default shadows darker relatively easily, and this also works with some effects and such too. I pretty much always do this with my models, works with what I do for the cel shaded look as well. Doesn't work with Raycast, but that's a whole different beast so makes sense it wouldn't.

I know I don't have tooo too many MMD users watching but yeah hey, hopefully someone finds this useful x3
