FAQ

Blockbench: UV Mapping

Definition

A UV map or just "UV" is the information in a model, which parts of a texture are shown on which parts of a model. UVs can overlap and hence cause several parts to use the same area on the texture.

Editing a UV Map

You can edit a UV-map trough the UV window in the top left.
Make sure to have a cube selected which you want to UV map and freely resize/move the selection box in the UV window.
You cannot resize the UV selection if you're using Box UV

What do the value fields below the UV window mean?

Per-face UV: The first two values are the x/y position (with 0/0 being in the top left
corner) of the UV map, and the last two values its width and height.
Box UV: The 2 values are the x/y position of the UV map. The size of the UV map depends on the size of the respective cube.

I don't wanna bother with any of that, just let me draw on the model!:

Select all elements (Ctrl+A) and, create a new texture and make sure to select "Template" as type.
This will create a new texture that will keep already existing texture information, but assigns each element a unique section in the texture.

the warnings mean that you have faces with a texture that's 0 pixels tall

generally this will not cause issues but it's good practice to remove those faces

because they can in some cases cause problems and they also affect performance

Am removing the face still not fixing problem

:/
