I have a scene that is bogging blender down badly. Both during playback, selecting objects or moving keyframes. It’s driving me mad.
Now, when all the objects are onscreen (about 1500 objects, each with animated modifiers) this is understandable.
However, if I hide all the animated geometry, the frame rate improves slightly but not by much. I have absolutely nothing onscreen and I’m still getting 2-3 fps. Selection of objects in the outliner is painfully slow as is modifiying keyframes in the dopesheet. Even with NOTHING visible on screen.
Why is this? is blender calculating all of my modifiers per frame even though they are not visible? That seems awfully inefficient. Is there a way to keep blender from calculating hidden geometry? If it’s not the geometry, what’s going on behind the scenes here?
Does anyone have any experience with working with large scenes and dealing with blender slowing down to a crawl? Any tips?
