sculpting details (question)

I was talking to my general 3-d artist

He told me, it could be possible to sculpt in Zbrush (or other programs) if you have a good bump map

But I"m curious of how to do it

I know in Zbrush, you can make an alpha brush, but that seems to only work best for smaller areas

Any ideas on how I could do this?

    I'm by no means a professional, but if you reduce the mesh to the lowest quality and minimum subdivisions you can export it as an OBJ and do some organic modeling using a free software called "sculptris" and then just reimport it as a morph dial.

    If you're unfamiliar with making morphs there are tons of great tutorials on exporting, importing and re-rigging for large changes. All very simple. Remember, you MUST keep the same poly count. I spent 3-4 hours making a FBM that I accidentally added polys to... It was a sad night.

    Yeah...I can NOT keep the same poly count

    What's the point of the whole new HD system then?

    I'm not going to be able to make decent lip cracks (or even pores) on a 20k poly-count model

    Unfortunately the HD system is something Daz and PAs cannot disclose on. Us mere mortals have no idea how to create proper HD morphs (if we try it, we get the geometry mis-match error). If that's what you're trying to do, create HD morphs for Daz figures, you're going to hit a brick wall.

    We're left with using bump, displacement, and normal mapping methods to get the look without actually modeling anything.

    No, I KNOW how to sculpt (there is not brick wall there)

    all those maps are worthless

    I was asking how to USE a bump map to sculpt in Zbrush

    What do you mean - apply a bump map that already exists to the mesh and then further modify it? What are you trying to achieve?

    Instead of using alpha maps (which is what you do in for Zbrush)

    If there is a way to just use the bump map of a skin texture, and use the bump to sculpt the details, in 1 go

    Yes, I just did it a couple of hours ago.

    Is there a video showing how to do it?

    I think I found 1, but I can't watch it now to know

    I'm still not sure what you want to do - if you want to take a finished, whole figure, bump map and use that as an alpha aligned with the figure then it sounds as if you are wanting to copy the bump map as a starting point. If you are wanting to use a section as an alpha, chop it out in an image editor and load as an alpha. Remembering, of course, to respect copyright and licensing terms.
