Thanks for such a response! It works now and I think the reason is the game resolution was bigger than my image size. I assume image should be the same size your game res is or higher.
What to do with Embed BG? No matter how many times I change the image resolution there's an ugly gap forcing the edges tiling. Can't tell whether I should try on picking the random dimensions manually till the correct result appears or this is how it supposed to work in the first place?
