Hello everyone...I'm going to be doing a lot of detailing on this model, but I believe others can make use of it in its present state.
This is my 'Guinnivere', featuing the new rig, color-coded for easy use, and using Blender 2.72, which has some wonderfully sophisticated developments in mesh modelling.
Note: when I first created the gown, it was all once piece. I discovered that Blender's automatic weighting algorithm doesn't like gowns. It got arms and legs all confused.
So, I had to create a bodice with sleeves and a skirt, to get the weight painting right. Also, automatic weight painting goes very light on full weight (red or 1.00); which of course is the exact opposite of what happens when you assign vertex groups manually.
I'm using the designs from http://www.lindsayfleming.co.uk for my basic templates; after that, I will use ancient Celtic jewellery to detail the gown, so that I don't create a copyright problem.
You can try the model for yourself. Have fun!
