I actually don't drink coffee, but I came across this CGsociety thread last night and it piqued my curiosity. The thread houses an excellent, in-depth discussion about how to create a coffee shader in Maya using mia_x material. If you know me personally, then I'm sure you're not surprised at how I obsessed over this inconsequential, minute detail... After many, many hours of fiddling, this is what I've come up with:
I also took the liberty of populating the desk with random items! My coffee shader is still not as good as some of the ones in the thread, but I think it's time to move on (aka MRP is beckoning me)...
This sort of contributes to my MRP (5 seconds worth?!) and I'm learning so this shouldn't count as procrastination, right?!
EDIT: And yes, this shall be cold, stale coffee because I'm not willing to attempt steam right now lol.
