No, it was meant just for levels within one layer. > Another point : apart from performance issue, I cannot see any reason > why *not* to enable symbol levels. Are there situations were users do > want different symbol layers to overlap ? I think there are such situations, from the top of my head: - with symbol levels you cannot see the rendering progress (everything is rendered at the end) - this makes quite a difference with big layers - you don't always want the symbol layers to be blended (different appearance) - not all renderers need to support symbol levels I don't think we should go with symbol levels always on.
