Make a big scene faster?

Unity Engine
1

I have a big scene in unity now. But it is slow.
I have used occlution culling but it is still slow

My scene have alot of lights, and if i turn them of. My scene isn’t slow anymore.
Have anyone a idea to turn the lights of when i can’t see them, or another solution.

Thanks!

does all of your lights have shadows on? and since your scene is big have you tried the practices for lowering draw calls? how many draw calls are you getting?

Since you’re in pro (or I assume you are) switch to deferred rendering if you’re not already. If that doesn’t help then you may want to create a backup or duplicate of the scene and try lightmapping and see how that turns out.

There’s always light probes. Those will make it seem as fast as no lights on a desktop.

yes i have pro, i have already different rendering. but my scene isn’t done. can i lightmap it then?

6

see the profiler.
in the begin is with lights and when it is a bit lower there the scene is without lights.

i thinks the lights are the problem

You’ll need to follow the tips provided and also those which are described in the docs, like:

  • Bake lightning instead of using all realtime shadowed lights
  • Combine geometry
  • Share materials
    → In general: Lower draw calls.

yep the main ideal would be lowering the drawcalls for example for a standalong i would try to go below 1k for mobile i believe it should be aorund 300 and same for mobile
