Negative effects of using too many lights ?

[csbx]

I'm getting some weird effects in my cell where dynamic objects disappear, turn dark, depending on the angle at which the player is looking. I'm wondering if this is because I am using too may lights. It could also be related to rooms + portals, but I have no idea.

 

Anyone have this issue before ?

indeed,

this optimization thread has a lot of ideas to explore;

there are some issues when you apply different kinds of lighting in cells (UGRID/ Int-to-Ext matching etc)

some folks are working on placeable node-based dynamic occlusion and 'just-in-time/FIFO" regen stuff

which will alleviate some of those 'what-the'?! moments.

 

I have this issue mostly in the "Diamond City Restored" mod area,

the neon-lights all coming on at dusk cause a massive momentary framerate spike.

Hangman's Alley/Bazaar also has a lot of 2D-3D Decal Appliques which simulate the interior areas having lights come on etc, that can cause framerates

or failure-to-play/seam issues.

I also have odd issues with the Great Domed CIT dome, from the way the dome segments are angled.

The dome is a test mirrored surface to reflect the interior restored settlement as a decal surface... but, it doesn't always work properly hehe.

Thanks. I'll continue poking, but after a dozen or so pages it looks to be mostly about pre-combined meshes--something that I don't think should affect my new internal cell--or should it ? Does everyone who makes a mod that adds a cell "Generate *Precombined* Visibility for Loaded Area" ?

 

edit: ah--just noticed the spoiler tag with more specifics re: lights. Will read up.

Are you editing a vanilla cell or a scratch made one? If you copied a vanilla cell or are working on a vanilla cell, chances are good that what you see is the sloppy work BGS did with roombounds and occlusion planes.

Thanks. I dup'd the BOS holding cell, deleted all meshes, lights, portals, roombounds. So it's a new cell to which I've added bounds, occlusion planes.

 

I'm getting 60fps, and run with 4gigs VRAM and 16gigs RAM with no stuttering--so this isn't a memory or hardware constraint here. I've also not noticed this effect in the vanilla game EXCEPT one area near Diamond City where parts of a building disappear depending on view--that, I think, is related to precombines. My issue here in an internal cell is different, I think.
