It is generally a good idea to use descriptive names, such as facade_industrial_old_white.png, but for this example we simply use facade.png. | It is generally a good idea to use descriptive names, such as facade_industrial_old_white.png, but for this example we simply use facade.png. | ||
# Calibrate the image width/height. Find a feature in the image whose dimensions you know or can estimate. For example, simple windows are typically about 0.8 m wide. Here, we're using the aircon's width, estimated 0.82 m. Left drag to select that horizontal feature, then enter its length. Right drag for a vertical feature. You need only one of them. If both are given, both are used (e.g. if your image is stretched in one direction). | # Calibrate the image width/height. Find a feature in the image whose dimensions you know or can estimate.

# Once you're satisfied, click "dump and quit". This writes calibration/cut data to a file "facade_24x19m.py". Note that texGUI added "_24x19m" to the texture file name (the original file is still in place), since you're likely to have more than one texture for an industrial facade. | # Once you're satisfied, click "dump and quit".
