Hello, community. I've created a new mechanic in my game: secret passages, upon entering which its front borders (walls) become translucent. and everything would be fine if it weren't for these vile intersections of walls, which become many times more saturated against the background of everything else. I wonder if I can somehow contribute to the fact that alpha blending did not work for children of one node, or can I combine all the sprites in the object into one single sprite, inside the engine? If all of that is impossible, then how to achieve the result that I want? Thanks in advance for your feedback.
