Moving the camera around shows light pop in weirdly

[aflacc]

Description

I don't know if theres a setting i missed, but when i move my pov around I can catch lighting before it actually shows, I want to say it's like a 1/4~ second delay but its noticable enough that I can't not notice it. anything that Emits light takes a moment to actually visually emit that light, like torches, amethyst. etc. I tried all the different preset options to see if maybe the one I was on just didnt have a setting on or something, and it happens on even the highest preset

don't really know if the logs will say anything important relating to this, but i'm required to add them, so heres just a session of me recording that video

at the time i recorded this I was using a outdated version of the shaderpack and hadn't realized, but on updating it still happens. just thought i should mention that

I think this might be a tech limitation of renderpearl, I encountered this one often too

Hi!
Yes, this is caused by RenderPearl not updating its light list every frame, together with the fact that only lights from visible chunks are included. It's controllable by the Lighting -> Light List -> Refresh Rate option down to every other frame, but can't be entirely disabled with the current design

I will try to make the light list creation happen spread out over all frames to hopefully be able to increase the default refresh rate

I also appreciate you providing a log! Compatibility problems with graphics drivers and mods can cause issues without the shader pack failing to load, which the log helps a lot to diagnose

uh, i think i have some stuff to share with you too, that being said, sometimes the light would disappear when i turn my sight around (even if the light source is inside my sight sometimes), is this tech limitation too?

Visible lights can disappear because they're too far away (controlled by LOD Falloff), but that shouldn't happen if you're just turning while standing still. Then the likely cause is that the light list is being completely filled up, causing lights to be skipped randomly. You can try modifying Capacity, Distance, LOD Falloff and Lava LOD Bias in Lighting -> Light List to avoid this (see tooltip descriptions for what they do)

The maximum capacity of the light list depends on the amount of memory the GPU can allocate for shared variables, and the default value in the Gold and higher profiles is set to the highest amount that's guaranteed to work everywhere
