Crazybump and Daz

I was playing with Crazybump, trying to learn how to use the adjustment sliders to make better Normal maps, but I have no idea which parameters I should edit to make a good Normal map for human skin. I searched with Google, but all the CB tutorials I found were for objects, I couldn't find nothing that could help me.
Any suggestions?

    It's mostly a case of what images you're putting into it. In CB, it's mostly down to tweaking the intensity, and focus on the fine-midrange controls.

    What issues are you having exactly?

    Thanks for the quick answer.
    I'm trying to replace some Bump maps for Normal maps to a M6 character. But I'm having a hard time to make them look even in the renders.
    I noticed the Normal maps that came with the M6 original textures have different intensities (or at least look that way). The face Normal map looks less detailed than the torso map, so I have two questions.
    - I should use the same settings in Crazybump for all the skin textures? or the torso and limbs should have a higher intensity than the face?
    - The Normal maps that came with the M6 character would work with a different skin set?
    Thanks in advance.

    What are you trying to do? I don't think Crazy Bump is for converting a bump map to a normal map, it's for creating bump/normal/diffuse etc. maps from source images. I'm not clear why you'd want to convert, if that's what you are doing, anyway - any speed gain is probably going to be pretty small (though I've never tested).

    I'm trying to make Normals from the Diffuse maps, to test if it will give me more render speed and see if the end result will look better (or at least different enough) from the Bump version.
    I don't know which parameters to use to get a good Normal map from the original Diffuse maps. Should I use the same parameters for all maps? Original Daz Normal maps looks more "detailed" on the torso than the face, so I should gave the torso a higher intensity in CB?
    I don't have any experience with using Normal maps for human skin, so any tip will be welcomed.

    You simply cannot make good Bump, Displacement or Normal (or Specular for that matter) maps from the figures Diffuse texture map. Normal maps are usually baked from a hi-res sculpt of the model.

    OK. Thanks for the help.
