Here's an experiment to try: How does the file size or RAM load differ between a scene that contains one large stamp, a scene that contains one large stamp that fully encloses a smaller stamp of a different colour, and a scene that contains one large stamp that fully encloses a smaller stamp of the same colour?Of course, the Undo buffer may obfuscate efforts to determine memory load from a model... is the Undo history preserved in the save file?
@kojack - good analysis. We don't spatially *partition* in the sense of octrees or anything (in practice wouldn't yield much perf benefit for anything we do, and just takes a little memory + bookkeeping), but the SDF is stored sparsely, so we don't allocate a block until you do something with it.That said, I'm pretty sure right now we don't reclaim blocks when you empty them.
