I'm sorry there is no proper documentation available yet. Here is some first aid. I hope you get started...
Mod Patcher Apply button greyed out, possible causes:
- SONAR is running. Close SONAR and try again.
- Target file is not set up correctly (sometimes automatic detection may fail depending on the SONAR version). Click Target field and select desired TTSRES*.DLL. SONAR X2 uses TTSRES100.dll, SONAR X1 uses TTSRES90.dll.
Load list is meaningful only if you have saved a list before. There are no preset lists available.
To start with Skylight Colors, I recommend you to extract images from the TTSRES100.dll. Launch Main menu | Customize | Extract Skylight graphics.... You will be asked for a target folder. Select any folder you like. Open folder in Explorer. There are two subfolders: PNG and Bitmap. PNG subfolder is more intersting because 95% of Skylight interface graphics are found there.
Next step: Open Skylight Colors window. Drag and drop PNG images to any location of Skylight Colors window and they will be added to the list on the left. Now you can play with presets and sliders. Preview window shows how image colors would be changed. After you have found good colors, select target for the files to be processed. Safest way is to store images back to files, generally to a new folder. You can also write images directly to the TTSRES100.dll (SONAR must be closed) or to an existing mod (currently Skylight Colors can not create a new mod file but it can overwrite/append an existing mod).
Now it's time to save list of images. Click Save list button and enter filename.
