thanks, solved it, thanks to you, found the worms.capx you shared, but it wasnt diferent from pasting an object over another, however, i did switched the eraser blend option to destination out, and its doing exactly the thing in picture, now i need to adapt it and hopefully will work, with my drawing game, (thats like a paint program, made with events, not using canvas object cause its weird in shape creation ,so i use images, and spawn in some parts, so i think will solved my issue) thanks alot
