Poser users are visual, so tutorials should focus on effects and how to evolve them.

For example, a tutorial on creating a stone shader needs to show the following types of steps:

• start with an object and add a stone type color
• add bump and displacement and now it looks a little more like a rock
• add a granite or other node to give it more realism
• tweak the granite settings to show how it adds or detracts from that realism
• maybe add a second color to vary the material
• tweak those settings

Artists aren't interested in the details involved in the math. They're interested in how changes affect their image. It's more work and makes it harder to cover the larger ground that's needed, but it's what artists need.

An example of what not to show in a tutorial would be the BB link

This is excellent information for somebody that's getting deep into node math, but the average artist only wants to know how it can be used to enhance an existing material node effect being created.

A tutorial on the render settings, and which should be changed for an optimal image, would be useful. I remember having trouble with atmospherics in an image and it wasn't very straightforward how to achieve the best results.
