Question for the Guru's...

I have a question. Would it at all be possible to say, sketch my image in b/w on paper, scan it in, clean it up etc… and then somehow kind of “mold” a clay sphere or what not around the drawing. Then say later, remove the b/w drawing that I used. I mean, could you somehow map the image onto a pre-molded sphere (kind of the shape of a head) and then slap it on (texture) wise and Zadd/Zsub the drawing in the clay.

Sorry, did anyone have a hard time understanding that? I had a hard time explaining it.

Well, if your asking whether or not you can use a sketch to help you model, definatly yes! But usually people just fill the background with the sketch, and model over it. It may be helpful to go into move, scale, or rotate mode, (but NOT edit object mode) and decrease the RGB Intensity so the sketch shows through.
If you tried to put the sketch directly on an unmodeled sphere, I guess the sketch would just get messed up as you modeled…

i would like add my little tid bit to this topic if i can… muvlo is right this is a awesome step to do… import your scanned image in zbrush as a texture…change the doc size to the image, create a 2nd layer and begin your modeling that way you can delete your first layer after modeling… you can always create more layers and add more stuff to it. also you can hide the layer my turning the layer from yellow to gray that way you can use the new layer to create texture or use the texture master to create texture your models… hope this helps…

I do it.

  1. Make a layer to the size of your cleaned scan. I often use part of the scan (ie. a head and I find inverting it (negative) helps when it is brought into ZB. THis one was 1000x1000 for the head.

  2. Use DOCUMENT>IMPORT with FLAT material selected. This puts your image into a layer.

  3. Make a new layer

  4. Place a 3D sphere or similar into the document window. Increase its mesh res. in the TOO>MODIFIERS>INITIALIZE panel

  5. Turn on DOTS in the PREFERENCE panel

  6. Model your mesh in WIREFRAME (DOTS) using DRAW and MOVE in the TRANSFORM panel. As you are using DOTS (WireFrame) you can see your image on the lower layer and can easily match its shape.

Switch back and to DOTS to help you model.
Hope this helps.

Thanks for this information. I always thought it was possible, but just did not know how to do it.

Rather than using the “dots” method like Southern mentioned above, I also use the method where I make the material that I’m working with transparent and I turn the “flatten layers” button to off in the render pallette. That way, I can see through my model to the background sketch.

I didn’t think of using the “dots” method myself. I’ll have to give that a try sometime as well.

Thank you Southern. That’s exactly what I was talking about.

You have a great minds eye.
