This gives you all of the power necessary to align textures properly. I won’t go over every single control here since it should be mostly self explanatory but a few things warrant explanation.
The up/down spinner controls beside the various fields work as positive and negative buttons. For example, if you are working with the “U Offset” field and click the UP arrow it will pan by 4 texels on the U axis. If you click the DOWN arrow, it will pan by -4. This works the same for all of the spinner controls and allows you to pan each direction very easily.
Scaling has a number of handy buttons that will flip or scale the texture quickly.
The “Default” button resets the face to the default Quake texture alignment if you mess with it too much and just want to pull the rip cord and start over.
Keyboard Shortcuts
This is probably where you’ll be spending most of your time even though it’s more complicated. When you select faces in the editor, you can tweak the alignment just by using the cursor keys. This makes it quick and easy to get things looking right.
It breaks down like this:
CURSOR_KEY - Panning (hold down SHIFT for larger increments)
CMD+CURSOR_KEY - Rotation (hold down SHIFT for larger increments)
OPTION+CMD+CURSOR_KEY - Scale by 0.1 units
SHIFT+OPTION+CMD+CURSOR_KEY = Flip
That looks hideously complex but you’ll find it’s pretty easy once you try it a few times. It’s certainly easier than calling up the inspector window and clicking buttons each time!
