Ok so this new picture im working on i ran into some sort of problem. It seems that there skin has a grainy look to it. How do i fix this. could it be something in my lighting settings? (attached picture of settings) or could it be that the scene im using is casting some sort of shadow over there skin?

 

You guys are always the best here so i figured i would ask here before i drive myself nuts lol

 

Thanks again!

I was about to say that your Shadow blur radius might be too high judging from deep shadows on the left.  Now, again, which Poser version are you using and what are your render settings under either D3D's render script or manual setting of the Render's Firefly?

If it is a shadow problem (i can't see too well on my phone) you could try raising the shadow samples. Try 50+(?)

May be something is wrong in your shader ...

Your shader is trying to do very small freckles and your shading rate is too high. The result is you are getting aliasing of these small features into large ones. It's not really there.

Change your render setting Min Shading Rate to .2 and see how that goes. Then work back higher to recover speed until you find a compromise you like.

Or - get a shader expert to fix the shaders.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)

there's probably no way OP is using a procedural freckle overlay/freckle map blended over the skin map, hence render with shade rate= 0.2 should fix it.

Ok so lowering the min shade rate to .2 worked =-)

 

Now for some reason im getting what looks to be a dirty shadow on my figure. Could this be from my light settings or could it be a shadow from somewhere in the scene that im using?

Oh and im using poser pro 2012 with the ezskin shader applyed.

That looks like a blurred shadow from a tree. Try raising the RT shadow samples. It may still look like a dirty shadow, but it'll be smoother. (I use shadow samples of 50 or higher)
