Note: There is a "Print this" link on each page that will produce a printable version of the tutorial without the background images, and with the thumbnails replaced with the full illustrations. This may take a little longer to load, depending on the sizes of the images.
The first one of these is on making a head for DS. I used a simple shape for the head so anyone could model along with me, and produced Asparagorn - half Elf, half Vegetable. He now appears in Abstraction as a denizen of a rather strange part of that world.
That tutorial has been copied onto a number of other sites, without attribution. One of them even had the nerve to link to the images here!
The next is about ornaments. These are additional pieces of armor that can be defined in a template as an extra mesh to supplement the base one. DS2 uses these for Collars, Shoulder plates and spikes, and I've used the technique for a bunny tail (and a tray).
A common idea is to have a version of a monster or neutral ambient as a member of your party. This tutorial explains how to do that.
I'll add more as I think of them. Flick probably needs a few, but I'm not sure where to start.
