Guys, I discovered an amazing feature in the editor.
I've almost finished the map (it seems to be turning out well), but here's the catch:
The game runs without glitches, but only on the lowest settings, and I created the map with maximum graphics settings. After completing half of the map, I decided to test it, and guess what? The graphics are set to maximum, and it runs perfectly, even in a battle with 2,000 Titans, without a single extra glitch. How is that possible?
