I need to model viens--basically organic looking tubes that bifurcate, and re-bifurcate, while getting smaller. (For example picture all of the viens in your arms as they taper into your hand, fingers and then finger tips).
Is there any way to do this without modeling every single one independently?
Any thoughts or ideas appreciated. I dont know how to script. Maybe there's an existing script that does something similar?

cool idea, but i need the viens to be polygons--they need to be 3D hollow objects. so I can pan the camera around and view them from multiple angles--not just surface texture.
any ideas on that?

You can convert paint fx to polygons, so that should work okay.

If you need to do it precisely you could always use curves and extrude the cap faces of a polygonal cylinder along them. It wouldn't take long, and the parts where the veins meet could just be faces pulled inside other veins and look pretty realistic.

I agree with stwert...you can convert to poly's from paint. Or you could do it in Zbrush?? How do you mean Acid? as in a good sub poly tube and grab random faces and extrude?? What about making the surface live? and CV it wouldnt take long either?
