Why are UV maps the glue between models and textures?
The reason why a UV map is the glue between model and textures is that it’s not only the flattened and mapped topology of your model, it’s also the basis for your map bakes. This means you need to take your mapping into consideration as you model – bad UVs give bad bakes.
What’s the best way to do UV mapping?
You can of course work around this by using triplanar mapping when working in apps such as Substance Designer, for example, but the best thing is to get it right straight out of the gate. As well as no distortion, a good UV map also has borders and padding.
What’s the best way to communicate with UV modeler?
If you’re a texture painter and you’re not unwrapping, it is equally important to communicate with the modeler who is dealing with the UV’s. Let him know if you have any specific request in advance, such as organization, specific cuts and etc.
What should the UV grid look like in Photoshop?
The UV grid should have letters and shapes on it – the plain black, checkered map is not good for spotting errors like flipped polys and smaller distortions, even if your UV mapper shows stretch (blue) or pinch (red) in the model view. The patience is because UV mapping can be time-consuming.
How to get rid of green seams on UVW?
If you want to re-do the UV map from scratch, then create new seams in the Viewport (not UVW Edit Window) using the “Edit Seams” or “Point-to-Point Seams” tools under Peel rollout. You can hide the exhisting “green” map seams while you do this. It shouldn’t take too long if you’re familiar with the UV Unwrapping.
Why do you need a UV mapping tool?
However, if you get into the habit of doing a little prep and find a UV mapping tool you click with, it’s not quite the tedium it used to be. The reason why a UV map is the glue between model and textures is that it’s not only the flattened and mapped topology of your model, it’s also the basis for your map bakes.
How to avoid seam problems with UV mapping?
Avoid seam trouble on the tile’s edges by adding a three- to four-pixel border, and get into the habit of creating enough space between your UV islands to handle edge padding and gutters to head off trouble at the pass.
