I have a few things I am trying to accomplish but would like a better technical understanding of what a terrain is. I have one, it is a park with tiles on the ground, grass and other assets sitting on it. I wanted to hide all these objects (to show photosphere images in their entirety). I did this by creating a second GO with a terrain collider that references the park terrain data in the Terrain Collider/Terrain Data field. I have not assigned the Terrain Data of the park which is why I think it works. Players can basically walk along the terrain (of the park) while no park is visible. Ideally however I would like it to have its own terrain data but one that mostly matches the park terrain minus everything that looks like the park, i.e. the ground tiles and grass. Is there a way to a) copy the data b) adjust the textures such that everything becomes transparent and/or I could add some effects by just changing the textures? It works now but it is a kludge. I also want to add a 3rd terrain. This would have to have the same basic outline as the park as well but again I could change the look and feel and add other assets on top of it. This would permit me to swap the "scenery" while in-game and players just keep walking around. They do not fall through the floor and stuff. Bonus question. Once one has say drawn something on a terrain can it be "undrawn"? I don't know what it means but I just want to get rid of the stuff that looks like a park without changing the bumps, height and such of the park terrain. If there is a "hill" I would just want to make the hill a different texture without actually drawing the hill again.
