#So I turned teh global light to 0 and

What "global light" precisely?

#

There's directional lights and environmental light

#

Both of them could be considered global, more or less

#

Ah, I meant teh Environmenl light

#

and i did change those point light shadow settings.. still no shadows though.. and yes, checked it for the object..

safe agate
#

I suggest to make a new test scene

#

With two default cubes next to each other and a point light with shadows enabled
One should verifiably cast shadows onto the other

#

...let me try something.. I'm going to change teh point light to

safe agate
#

If not, check project quality settings to ensure that additional pixel lights and shadows are not disabled

#

Nope.. for shits n giggle I changed to directional light and still no shadow light the global light

#

Next in the same test scene using the Lighting window set Environment Lighting Source to "color" and set the color to pure black

#

(You may need to hit the generate lighting button but ensure that baked lightmapping is disabled from the Lighting window for now)

#

Now verifiably the faces of the cubes facing away from your test light should be fully dark

#

@neat mural Your additional lights are not per pixel, but per vertex

neat mural
#

Not what I expected

safe agate
#

That's one of the quality settings to save performance, and it doesn't support shadowing

neat mural
#

Going to try what you asked

safe agate
#

You'll need to increase pixel light limit and/or make sure additional pixel lights aren't disabled in quality settings to get shadows

#

And that shadows aren't disabled in quality settings as well

#

Environmental lighting problem is not related to that, however

neat mural
#

Sorry, where do I find the quality settings?

safe agate
#

"Project" window

neat mural
#

I did as you suggested.. and I do see the far side fo teh cubs as full dark...

safe agate

#

I'm in there, but don't see quality settings

safe agate
#

"Quality" tab

K, in there... only shadow option is

#

Shadowmask mode

safe agate
#

If you are using URP, Quality tab will contain references to URP assets rather than the plainly the quality settings alone
Clicking on the URP asset reference will take you to its location in Project window and let you edit it in Inspector

#

There you find the rest of the quality settings

That is more expected!

Let me see if it looks better in my working file

safe agate
#

Now, this fix probably doesn't stop your level's interior from being lit by outside ambient lighting

neat mural
#

Right...

#

and we have shadows.. but now it seems random, lol... and some spot lights aren't working.. lol.. will play more..

safe agate
#

And there isn't really a simple or versatile way to "occlude" a volume in the scene from ambient lighting

neat mural
#

ah

safe agate

Pixel lights are limited per mesh, which is what the "light limit" you saw in the URP asset refers to

#

The simplest way to get around it is to increase the light limit, slice meshes into smaller parts and limit light ranges, to not hit the limit

#

But there's also deferred rendering path and forward+ rendering path that give you basically unlimited pixel lights, with their own drawbacks

neat mural
#

Well, the Spatial SDK doesn't deal with shadows apparently!!

safe agate
#

Light limits aren't for shadows but pixel (non vertex) lights as a whole

neat mural

#

As for occluding interiors from outside ambient lighting, you need reflection probes and light probes, or just set the ambient lighting to black/dark color and get by with the whole scene using that ambient color
Unfortunately light probes require baked lightmapping which is a whole workflow
I don't know why they could not implement simple probes or volumes that don't need baking for occluding ambient lighting

#

For Sptaial perforamce I do have to bake lighting... but want to make sure it looks good before hand:-)

Well, you certainly got me ahead of where i was, thank you so very much @safe agate !

Good luck! I must leave for now
