I am Poser PP myself and mainly render in Cinema4d but the same priciples apply- If you are using Poser 5, you you could mix up a shader with a speckly noise controlling the strength of the specular highlight, and maybe a matching bump map as well. Maybe add to this a directional falloff that will favour ( or restrict to )upper surfaces for the effect. I would layer this over the base skin in the shaders/materials. That is roughly how I would approach it in most 3d proggies like C4d or MAX where shaders can be mixed & layered and from what I understand should be do-able with Firefly. Lesh
