I have a scene that contains a group whose content consists of a large number of polygons (1000×500). I thought that by settings cache = true and/or cacheHint.SPEED at the group level that a single internal bitmap would be utilized for the numerous polygons. However this appears not to be the case–frame rate stuck at a ~2fps. Setting the cache on each polygon did not help either probably due to the large number of them.
Anyone know if setting cache at group level supposed to generate a single internal bitmap cache for the group?
The fix was to enable cache for the group element but set the cache for individuals off. I must have set to true for both.
