Created a rough and dirty 3D model to suit a quick purpose for a drawing. I didn't want to use the CSP default model as I find it lacking in skin identity by default (even though now you can draw on the models!) but I also just didn't want to import a whole model just to fuss with the whole arm and hand so instead I fussed with making a whole hand by scratch and rigging it and making skins for it instead LOL
2 Skins:
Contour skin: marking center-line of the top of the fingers, tendons on the back of the hand, and knuckles, as well as the side profile line (think of a glove)
Segmented skin: whole segments of fingers and knuckles are colour blocked to mark the planes of the finger (top, sides, and bottom), as well as the fat pad / callus markings, and the general large fat pads of the palm. The knuckles are segmented into triangles to dictate the front/back portion of them, as well as their triangulated "sides" of the knuckle to show their "sides" to better understand the planes as they turn away or towards you.
I will be making various "anthro-ified" scale of hands/paws in the future, but this was just for now.
This and other 3D csp asset models (rigged and static) are available for Everything Tier/ Blossom members to download in the Sub Only Discord via the respective Blossom Channel. Missed a model uploaded? No worries! There's a masterlist linking to each model you'd want!
I hope this is useful for you and the fact I made this so quickly within about 2 hours bodes well I think in my studying of how to make 3D Models and creating them for CSP use to hopefully make more complicated models in the future and other projects.
