The program generates a tile transition map from textures (using built-in masks). You can select how many textures will be mixed (1-4). And of course you can select any textures you want.
The program then combines these tiles into a tile set, and you can change the position of the tiles and change the number of columns.

All tiles can be used for commercial purposes.

Yes, you can save to PNG and use the output from this program in GameMaker, RPG Maker, Construct, AppGameKit, Tiled Map Editor,...
