Chocolate Research Day 1

OK, let's start.
For today my target will be build the base of shader, and the base parameter, very simple, and add the various features next time.
Usually i build the base shader on a simple primitive, like sphere, for focalize only colors.
The shader network for now it's very simple.
I did that in Houdini, because my research on Dynamic Fluid will be focalized on Houdini v.9.5.

But the shader teory it's the same, for all softwares.

This is the network in VEX Editor

This is the simple result

In 3d scene i have 3 standard spotlight and the standard lighting configuration (key, fill, rim).
For find a right way, i need to draw some notes on images, i find it very usefull.

So, now i have all ingredients for the next day.
