heightCtmGenerator

heightCtmGenerator is a program to generate height based CTM to make blocks look darker or lighter depending on the Y level.

To use, make a blocks folder next to the exe file. In here, place all of the textures you wish to have the CTM applied to.

If you want part of the texture to stay the same brightness, you can make a mask file for it. This texture should have the same name with _mask.png on the end. For example to mask stone.png, you make a stone_mask.png.

To match multiple in game textures with the same texture, make a .txt file with the same name as the texture, with a list of all the tile names in it. For example, for stone.png you would make stone.txt and write stone andesite granite in it.

From here, just run the program, and follow the instructions.

Files are outputted to an output folder.
