Hey @songtan, I'm hoping to be able to use this asset for a game. A couple of questions regarding customisability during play: -It would be useful to have quite a lot of variety in the grids. What would be good is to not have to make dozens of individual maps, but to perhaps have some preset layouts (a corridor or open area or battlefield), but then be able to customise them to add variety. So perhaps there's a type of location like a city street, but I want to change the contents in the scene depending on the situation. Perhaps there are more walls, or more chatic obstacles. Is it possible to make those sorts of changes, or are maps unchangable (position of walls, collectables etc) once they are saved in a scene? -Does each grid need to have a unique scene? Is there perhaps a way to save a map and then load it into a scene, including the placement of walls etc? -Perhaps I want to alter the visual style but keep the layout of the grid. Is it possible to change what prefabs (like walls, units, obstacles) for different ones before the scene starts? -If I have a party of units, which might increase or alter over time (along with add different weapons/abilities), is it possible to specify which units will be used in a scene upon loading it? Perhaps I have 12 different possible party members and I bring 4 into the scene with me? -Same with the enemies. I can procedurally spawn them it seems, but is it possible to alter the types of units spawned before the battle starts?
