Yes, that still on my "to do" list as well as everything else I listed. That period in 2016 was a big turning point for me and my birds. I had done the first four birds for SBRM Asia v1 and came to the conclusion that I really needed to update my base model set... so I shelved everything and started testing ways I could improved the models. I went through a period (2016-17) where I morphed a better Thigh/Hip connection where looked better but still wasn't cutting it. In frustration, I moved to new bird models (Kiwi, Nightjars) and stumbled on to the Nature Wonders line. With Vultures and Toucan reworkings, I bit the bullet and did a major reconstruction on the base geometry, sewing the thighs and hip together, solving those issues-- but trashing most of the existing morphs. It took a lot more time to do, but my efforts were worth it. Ever since then, I've slowly been moving through the older sets, occasionally adding in new sets for SBRM or NW.
Those first four birds from Asia v1 I did in back 2016 did to see the light of day in last years' Shorebirds v4 release. Somewhere, I do have a half started Hornbill model, which I will look at. As I mentioned a few pages ago in this thread, I have a completed Sage Grouse/Prairie Chicken model I did at the time I was creating the Peafowl, that I also need to get back too. To add to that, some friends, who have seen my completed Nature's Wonder model (that I completed and rigged in January) are begging me to finish that. Once I get the updates done, I'll be more free to do these projects. The problem is there aren't enough Kens to do everything I want to do... and if I did duplicate myself, the problem would be even worse because each Ken would be going in a different direction finding some new cool bird or critter to do.
