Sluggish view of animation - on a fast machine - when setting up scenes
on Jun 5, 2014 at 11:06:34 am

(Studio R14, Cinebench: CPU ->1176, OpenGL -> 126)

With my "decent speed machine" I'm having problems setting up animation in many scenes. They are very complex/heavy: Ocean animation; Relatively complex landscapes; Intricate Vessels. Many animated parts: Object-moves, radar antennaes, propellers, flashing lights, waves, moving vehicles on shore, etc.

I'm getting about 1 frame/sec at times - Some of the scenes are quite time-critical, and it is nearly impossible to get an idea of the animation flow until after render. Result: Repeated re-renders.

I've tried to turn off "everything not needed" - And set to "Box-view". Still sluggish... I've not tried to set the elements to different Layers yet, and turn un-needed Layers off. I'm not familiar with that. Could that possibly help?

What I'm about to do is to make a "mock-up" of Cubes and a Floor to find the right timing. - Then use data from THAT in the real project

Any other, better ideas? - I would be immensely thankful for any help on this!

Layers are a good idea. You might also adjust the level of detail down.

If you're using any cloners see if you can get away with enabling render instances.

Thanks Darby.

I'll certainly try Layers.

> You might also adjust the level of detail down.

How do I do that? Where? What kind of details?

No Clones used.

It should be in one of the editor menus. I don't recall exactly which one.

Even if you're not using Cloners you might try creating instances of any duplicate geometry that doesn't require point level animation. An instance of an object uses almost no memory while 2x a single object would normally require 2x the memory.

Probably the biggest CPU killer in terms of viewport performance is object number. If you have hundreds or thousands of objects that aren't animated you might see if you can join them into a single object, or at least fewer objects.

Adam

Thanks for the input! - Many Objects, but not in the thousands...

I could try to reduce numbers, but it is possibly easier to just do a "simplified" simulation (Cubes, Floor) of the time-critical Objects.

Wondering: When joining Objects extensively the textures for these single Objects could be numbered between 50-100. + Other (non-textured-) materials. Is there a limit?

BTW: Do you think turning OFF Layers would help?

Are you using dynamics? If so, have you baked them? Baking the dynamics will increase your scene size on disk but will eliminate any need to calculate dynamics per frame.

Of course it becomes difficult to iterate the settings on your dynamic objects if you're baking them every time.
