I want to make an interactive map. And thanks to the people on the forum, I’ve decided to do it as a decal. It works fine, but only sometimes, i.e. sometimes the decal is displayed, sometimes not. In the video below you can see how I just click “start simulation”, “stop simulation”, and each time a different region is displayed. Of course I have not changed anything in the blueprints, below I will attach the blueprints that are responsible for creating the decal, adding material to it, etc.
P.S. The most interesting thing is that the material used as a decal I took from other people, and in their project, it worked perfectly, while I have the opposite situation. Maybe the thing is that the project was on the version of the engine 4.27?
