Problem: When using WebGL for rendering tilemaps tiles might pick up tiny slices of neighboring tiles due to how WebGL uses textures. Solution: TileeExtruder separates tiles in an image and extend the border pixels so that the tiny slices blend in.
The repository is far from complete. You might manage to use it from node but probably not without going into the code, and the Phaser 3 plug-in will just generate errors ATM.
Just run "npm i" as usual BUT:
Unless previously installed you'll need Cairo. For system-specific installation view the Wiki.
