Lots of errors! What should I do?
Most common technical issues
1 – Corrupted Photoshop preferences file. No worries, you can reset it very easily, just hold all together Ctr-Alt-Shift (Cmd-Option-Shift for Mac) while starting Photoshop. You will see a dialog box, click yes. I do it every time when I see strange photoshop behavior. https://www.youtube.com/watch?v=q1OCITC-VYM
OR: Preferences > General > Reset Preferences On Quit
2 – Don’t forget to Load or Select from menu Brushes and Patterns (if Action has them). You have to do it every time if you are using another Set/Сollection of brushes or patterns. In other words, if you using “Brush Set A” and want to play “Action B”, you have to load “Brush Set B”. Photoshop can’t guess where did you place them, so load them every time before using Action.
3 – Layers. If your background layer is named like “Layer 0”, select the layer, go to “Layer – New – Background from Layer”. Also, the layer named ‘ga’ must be named as ga, not GA, or Ga etc.
4 – Critical state (you rewrited action or brushes/patterns). Delete action and brushes from Photoshop, and reinstall them again (easy way is double-click or drag and drop)
5 – Tools. Brush Opacity and Brush Flow must be at 100%
6 – Try to test Action with different images.
Sometimes Action can have errors because your image is too bright or too dark, or have very low contrast. In this case, action can’t get enough information to work with, and an error appears. Balance your image using Levels or Curves tool.
About size. Usually, I use images around 3500px, 300DPI or 72DPI. Don’t use very small or very big images because brushes have fixed size, and you have to balance proportions. For example, portraits can be used with 2500px and higher, but full-size characters must have a bigger size picture (3500-5000px). Because of proportions.
