SIO IV Shader allows users to customize their own shader by modifying the src file. Here is the tutorial:
For iOS
I advise you to use an app called Shaderly to write the GLSL codes, you can download it in AppStore.
For Android
I use MT files manager to write the codes.
For desktop
I don't have a PC, but I think VScode is a good choice.
No matter which platform you are, the steps following are same.
1. Rename the file sio4customfragment.src to sio4customfragment.fsh.(Skip this if you can open src files)
2. Open the file, find comment "Type commands below me", you will see an example.
3. Now you can start to customize your shader by typing commands.
4. Rename sio4customfragment.fsh back to sio4customfragment.src.
Attention
All the numbers you type must be a decimal. For example, 1 is incorrect, you should type 1.0. 10 is incorrect, 10.0 is correct.
