@hideki i think you can get versions of Sverchok and Animation Nodes for older Blenders. which are more powerful than geometry nodes, should you end up wanting them.

i don't do big scene renders with Blender i just remember that a lot of film stuff tends to use proxy scenes where a lot of the detail has been cut away so it still all fits on their workstation. and depending on the scene and effects therein, they can be rendered to individual render layers which are mixed in the compositor.

this lets them respond to weird queries like "what if we made the characters a different shade of blue" by just color mapping the render instead of sending it off to the server farm to bake again.

i dunno. stuff to think about.
