Massive Chalice work

I just wrapped up some VFX work for Double Fine's Massive Chalice.  Check out the Early Access trailer!

Along with battle, weather, and impact effects, there was a fun amount of shader work to be had.  The game's unique art style needed a matching look for the levels with water.  The shader below uses a few techniques to accomplish it:

• combination of sine wave and noise to modulate vertex height
• normals are quantized and accented with a rim color to complement the faceted art style
• two-layer scrolling froth at wave peaks, with subtle darkening of valleys
• shoreline ripples are calculated using a pre-rendered shadow map
