2D arrays are not a native type, so I don’t think you can build a 2D array from a string without using a Repeat. As the docs say: The Array2d compounds mimic an array of subarrays
So, here’s something I whipped out during my break from “real work” 🙂
Q: How can a seemingly empty array create user normals ???

You can quickly copy colors by dragging and dropping color chips. This comes in handy when you’re copying colors from one shader to another.
Multiple uniquely textured objects – having only one shader
Strands
Q: If I emit Strands from particles ( like rain streaks), and then spawning particles based on collisions with say a grid, the spawned particles inherit the strands, but they have this behavior where the strands are actually ahead of the actual particle from which they are supposed to trail.

In the Arnold standard shader, you use specular reflections when you want glossy reflections. There’s direct specular (the “classical” specular hightlight) and indirect specular (glossy/blurry reflections), and both are part of the same BRDF behaviour. In this screenshot, direct specular (Direct Scale) is turned off, so you see only the indirect specular reflections. The Roughness makes those reflections glossy.
So what’s up with the separate Reflection/Refraction tab? Well, that tab gives you an alternate way to do sharp, mirror reflections (with no blurring or glossiness). However, with Specular, you can get pretty much the same thing by setting the Roughness to 0:
Finally, since I mentioned the direct specular, here’s the shaderball with just the direct spec:
Here’s a modified version of Mr Laforge’s compound that does the extrusion length and inset based on polygon area. Yeah, it uses a Repeat so I don’t think you would use it on a dense mesh and then just leave it in the stack to be reevaluated over and over.
The main idea is that you have to store the polygon indices (and the lengths and insets) before you do the extrude.

Goodbye for now, mental ray. Arnold is now my default scene renderer 🙂
File > Preferences > Rendering
Now everytime I start Softimage or create a new scene, Arnold will be the scene renderer. And I’ll have an Arnold light by default (Arnold doesn’t support the default Softimage lights).
And you’ll have all the Arnold render channels.
The SItoA addon includes some events for setting up new scenes when Arnold is the default renderer.

Some fiddling around with Point in Volume…
Point in Volume returns True (1) if a point is inside the specified geometry, and False (0) otherwise. Remember, zero is False, non-zero is True.
You can plug that boolean output into a Topo compound, like so:
If you break it down, the above is just doing this:
