Thank you so much, I had assumed backface threshold affected the geometry only, and not the bake data. I turned it back to 100 and it fixed all my issues!

[@NerdHead]

I'm glad I could help😁

[@GocoYT]

Thank you - this issue was killing my frames in high object areas. I tried googling the issue for ages and finally found your video to help! :D

[@ArjanDuijs]

Occlusion portal
That's what I needed man thank you
I've got windows with custom transparent mesh renders

[@NerdHead]

I an just working on a windows & mirror tutorial

[@BadBanana]

@NerdHead actually it diddnt work in the end what I did was make the rooms non static so the insides weren't occluded.
I wanted them to be excluded from rendering when miles out but this was a workaround I ended up settling for.
Custom gfx can be cumbersome at times
I'd be interested to see your window tutorial
I have mirrors that work pretty well... Well... they're a bit wierd
They render the reflection of the scene but not the character facing them
I think real-time mirrors on mobile would be too heavy to have them all over the place considering how many I'd end up with in my city scene
But yeah
They work fine for what they are
Cheers

Thanks for the video dude, I´m making an isometric game and was under the impression the backface threshold was going going help me hide the back walls of my buildings but that doesn´t seems to be the case. I´m just gonna remove the back geometry directly in Blender. TY

[@NerdHead]

Happy to help😁
You can look up LOD in unity, this might help you in your case

[@slendiv13]

Thank you. You really made my life easier

Nice! What are you working on?

[@Disisameme]

i did it like in the video but unity i still rendering object behind other objects, anyone knows how to fix it?

[@hggyuu]

Do you fix it? I'm making maze and camera still visualize itself view but it shouldn't render when I standing under wall and don't see nothing behind, but it still render all camera view ahead

[@hymus8627]

When we bake it really work now right ?
because when we exit visaulize mode it look like nothing change but when we play it actually change right ?

[@NerdHead]

If it works in visualize mode, it will.
You can enable and disable this and check to see if the game stats (fps and batches) changed

[@hymus8627]

@@NerdHead Thank you my fps really change from 70-90 to 110-130

[@Stumpy_VR]

when i do that it makes everything dissapear

[@DwightPotvin]

I am unable to get this to work no matter what I try. I have the static set correctly, yet all I am getting is fulcrum culling. Small occlusee objects are not being culled out by large occluder objects. I have tried using occlusion areas and without them, same result.

[@NerdHead]

Hey, can you please send more info (what setting are you using, an image of your scene, are you using any assets?) and I will answer you as soon as I can.
You can send it in discord server

[@watercat1248]

thank but i still don't understand what is the occasion area
one other thing is eny way to make wean player is insane in room to disable all the other rooms for the view ?
(i know that is possible if i disable the room with code but what i say is if unity have system like this by default)
in my game i have created a system for dynamic camera range before even learn abut Occlusion Culling the way this system works is pretty simple wean the player is in close area the see less and wean the player is in open area the see feather it very semple code
this the triger eneter code
private void OnTriggerEnter(Collider collision)
{
if (collision.TryGetComponent(out CameraDistans Distans))
{ Distans.Viewview_Distance(ViewDistances); }
}
and this the code for you need to add to the player
public Camera camera;
public void Viewview_Distance(float ViewDistances)
{
camera.farClipPlane = ViewDistances;
}

[@NikkiMcMistie]

I must be doing something wrong... My camera still renders through walls no matter what I put as the parameters. All objects are static and are both ocluders and ocludees

[@NerdHead]

Aee you using external assets?

[@NikkiMcMistie]

@@NerdHead Yeah. It seems that it only works for models that have backfaces as well, like unity cubes.
I also did forget to click on bake for the static game objects so thats why nothing worked in the start lol

[@hggyuu]

​@@NikkiMcMistieSame problem, but I instisiate prefab walls on scene and then I can't bake it, it seems like it should be before starting scene, how to bake it after creating in play mode?

[@NikkiMcMistie]

@@hggyuu it should work after baking it in edit mode before generating the scene in play mode. worked for me in unity 2021 yesterday anyway

[@pranaygarg6443]

@@NerdHead @NikkiMcMistie same problem, I am using external assets but I have marked them occludee static, but still they are rendering through walls
