Trouble with UV Mapping

ZBrush Usage Questions
#1

Hi,

I am having trouble making UV Maps for a shirt and i’m not sure what i’m doing wrong. (I know the lines of my uv maps aren’t perfect)

When i apply for instance a striped pattern to the shirt each sections seems to go in different directions.

This is what i’ve been doing so far;

  • Separated into different polygroup (e.g sleeves, front/ back etc)
  • Uv Master > turn on symmetry + polygroups > Unwrap
  • export > into daz > apply striped texture

I have tried flipping them as well but i think i’m doing something wrong when i’m making the UV’s ( I am a newbie :smiley: )

If anyone has any suggestions or videos (i did try and search for one on uv maps for shirts) that would be great.

I’ve attached some pictures so you can hopefully see what i mean!

Thanks for any help! :slight_smile:

You really can’t just take a model, UV map it and then slap a pre-made texture on. The texture must always be painted for the UV mapping.

To do what you’re looking for, the easiest would be to subdivide the model now that you have it mapped. You’ll want a number of polys approximately equal to the texture size that you will export. (For a shirt like you’re making, probably 4 million polys – which is a 2K texture.)

Now load your striped texture into Spotlight. Square the model with the canvas and your overlaid texture. Then transfer the texture to the model. This uses your texture as a source to polypaint your model. Rotate the model a few times, squaring it with the canvas each time and re-align the Spotlight texture with it each time. You’ll be able to get the entire surface to match.

(If you wish, you can use masking to protect certain areas from receiving paint. This gives you greater control as you’re transferring – for example the cuffs and collar can have different texture orientation.)

When done, turn off Spotlight and then convert polypaint to texture. What you have painted on the model will be transferred to the texture map. And it will be perfectly laid out for your UV mapping.
