I made these props in 2018 for the Wolf Kennels, and was surprised to see them used all across the game (the pelts in particular). I never got a polish pass on them as I wanted to get them in context first, but they appear to have worked well enough! These days these are very low poly objects. The pelts were built to be resource light, using cards only at the edges and spine area, and improved for custom circumstances - though that never ended up being utilized by those who made use of them in the game. It was a first try, I could do far better today.
The bones had a "fresh" set and a "dry" set, where the dry set was made of individual pieces that could compose a partial spine but also be used as individual vertebrae and ribs for flexibility. The fresh spine was modeled straight so it could be bent and posed into multiple variants.
Thanks for looking!
