How to Rotate Photoshop Brushes
STEP 2, here’s where it gets good…
Now, in the brushes pallet (Window > Brushes) select “Brush Tip Shape.” I never noticed this as an option because of the check boxes next to all the other choices. Check out your options, flip X, flip Y, angle, even a dragging option. Too easy! You can just click and drag to the exact angle you need.
Here is a sample with the clouds rotated to all 4 corners. How celestial.
Quick and easy, but a huge time saver. I hope you found this to be helpful!
