Cloth Fabric Threading

ZBrush Usage Questions
#1

What techniques are people using to add fabric threading detail to clothing that contours properly with larger deformations? For example, if you look at pale’s images, the threading for all of his cloth flows in the appropriate direction. I’ve spent some time doing searches for an answer here on ZBC, but I haven’t found anything substantial.

Just so I’m clear, I am not asking about how to sculpt folds in cloth. I’m asking about detailing the fibers in the cloth. Like this:

Thanks

Thanks for the reply. I did a test using the demo soldier’s shirt and a cloth alpha from the download center. Not bad, it’s certainly a quick little method. Two problems I’m running into using this technique:

  1. Distortion of alpha pattern that seems connected with mesh density of certain areas.

  2. Not sure how to control scale of projected pattern. It’s obviously too big below.

this technique relies on automatic UV tiles, which in turn rely on the size and spacing of your polygons. In other words, you need to have as even a distribution of polygons as possible for this to work.

But you don’t have to sacrifice your topology either- Just make a copy of your original basemesh, and add loops in where they are needed, bring it into zbrush and flood it with your texture, then project those details onto your preferred topology.

Ok, I’m seeing how I can apply this to a technique that I like a little better. I’ll just lay out my UVs by hand in another app, making sure that the UV layout for any cloth is as straight (horizontally and vertically) as possible without causing stretching. Then I can make a black and white cloth texture map at whatever scale and dimensions I want and then apply that as an alpha in ZBrush and inflate as ghost666 originally mentioned.

I think that should work and also give me a little more control without having to add edgeloops.
