Well I figured out how to fix my previous mistake with my custom mane model for the Daz Horse 2 3d figure and then I decided to make a morph to temporarily fix the bending problem until I work out how to use Daz Studio’s rigging.
Fixing the broken geometry
At first I thought I’d lost around 8 hours worth of work with the mesh breaking on my object but luckily I had saved the base figure under a different name a couple of days previously so opened up the broken figure in NotePad++ (please note I always save my work uncompressed so that I can edit it if needed in a text editor) and searched for the .dsf file in it so that I could find it’s location. I then opened the dsf file folder up in windows explorer and changed the file extension to .dsfbak.
