Ok first off, this is mostly hypothetical (sp?) as I only have Poser 3 at the moment, and won't be able to upgrade for a few months at least (no work :( ) but I'm wanting to know about morphs now ;) I know how basic morphs work - Dr. Geep's tut on the subject was very helpful - but I've seen examples of more advanced morphs that don't seem to follow the "don't add/delete any vertices" rule. I'll use the MilDragon as an example (note that I don't have MilDragon though). The dragon's morphs include adding spines, ears, and other things that seem to add more vertices than the model had originally. Now, the reason I'm asking about this is that I'd like to make some morphs and texture maps for the dolphin - specificlly, morphs to create Ecco the Dolphin characters ;) Most of them would require some pretty drastic changes, so I'm just wondering how one creates complicated morphs like the dragon's spines, if such are morphs at all.
