Like i said, it should matter if i"m going head screen shots, group photo, body model. I’m going to do it all, It’s not going to be one or the other
I just need ways to change the skin.
As Richard and I have suggested, you can start by trying to do this with changing the diffusion color. You will need to set up at least some primitive lighting and do some renders to judge whether the results are satisfactory. How the skin looks in the preview window is not a good guide to how it will look when rendered. You will need to render it.
Select a character with the skin applied. Go to the surface tab and expand all the surface areas. Use cntrl-click to select all the sections that start with “skin”. You will need to make the same changes in all of them so the seams where the different skin sections join do not show with different skin tones. For properties like the diffusion color, you can do this by just cntrl-click selecting all the skin sections and changing the diffusion color in all of them at once.
Your skin will probably have white in the diffusion color. Start by adding small amount of pink, yellow, orange, blue colors so it is just a little off white color. Render your figure and see how it looks. See if you can achieve what you want this way.
If you want to try using SubSurface scattering, along with a diffusion color, to change the skin tone, you will have to use the HumanSurface or the UberSurface shader. These shaders are more complicated, although it is always possible your skin is already using one of these. You can tell what shader it is using by selecting one of the skin regions on the expanded surface panel. At the top it will give you the name of the shader it is using. If it says, DAZ Default or something like that, that is the basic shader. If it says omHumanSurface or omUberSurface, that is a more complicated shader that includes subsurface scattering.
I would not recommend using ambient or specular adjustments to change skin tone, but some vendors use the ambient.
