Texture Darkening

If you want a object's texture to be darker, create another object in the exact same position and give it this action:

Slightly darker: create texture black mask=semitrans10

Darker: create texture black mask=semitrans06

The semitrans mask is a series of masks, where the higher then number, the more transparent it will be. Experiment with the other numbers (01 through 14) for other levels of brightness.

Warning: A masked object in the exact same position as another object will cause overlapping glitches in OpenGL video rendering mode.
