Optimize Camera rendering

Hi everyone! Hope you are having a great summer so far.

I’m working on a new animation scene. The setup is meant to look like the Batman garage from Cristopher Nolan’s Batman movies. Scene is looking pretty neat after spending a huge amount of time trying to get the vibe of the film. I already used a lot of textures, decals, objects, etc to make it look as close as possible to the movie.



The problem right now is that the scene is so heavy I’m having trouble making the actual animation. I was wondering if there’s some sort of shortcut/config to keep the objects that are not being framed by the cameras outside of the loading process so that I can focus on making a good seamless animation without having to worry about Blender going so slow everytime I want to change a camera angle.

I already have activated “Persistent data” but I’m pretty sure there has to be something similar to avoid loading all the objects before testing if those objects are not appearing in the scene.

Thanks in advance, any help is really appreciated.

(Also any feedback regarding the scene itself would be helpful before rendering out anything)

Thanks!!

Use render region in all camera view, won’t render what is outside. Ctrl + B.

How is this scene heavy? There aren’t that many objects, something must be wrong that makes things heavier than necessary, or there are loads of objects out of view that you aren’t showing.

I would check a few things.

  • Are there objects with subdivision modifiers? If yes, check that their level isn’t higher than needed. Subdivision is exponential, each level multiplies the polygon count by 4x. Also, turn their viewport levels down, you don’t need the full quality to place a camera in the viewport.

  • Any object with super dense geometry? If yes, could it be replaced with a decimated version, or one that’s been remeshed and baked to textures?

  • Does anything have a long chain of modifiers or geometry nodes? Those need to be recalculated after any change and can slow down the viewport a lot. Either apply them or turn their viewport visibility off (but keep their render visibility on).

Look up “geometry nodes camera culling.”

It’s a simple scene with not many objects.
I think we need to find the reason why the scene is heavy first. :thinking:

If the problem is that the hardware specification is low, you can use Simply, or you can create scenes from very simple objects, animate them, and replace them with existing scenes to render them. :slightly_smiling_face:

It didn’t end up being that heavy, but it took a while to load the objects, maybe because of the 4K textures. But I’ll definitely look up the camera culling, I was talking about something like that where you can omit some objects that are not going to be in the camera angle.

Thanks everyone!
