Love the work done here. I do have a recommendation. Instead of using standard shader with a high smoothness value for anything made from latex, try MToon with a matcap. Ideally, that will prevent the body from looking out of place in terms of shading. Create a black texture with 2 white splotches. This will be your matcap. I recommend a resolution of 512x512 for this. I made my matcaps in PDN. Most of my models have all the materials atlased in blender, so that’s why the entire body looks shiny on some of them. I’m waiting on an update to MToon shader that allows for making a mask for matcaps, so only some parts appear shiny.
