Its weird, that you have several different scalings in your lightmap (you can see this in the different checkerboard sizes)
Can you show the lightmap bake settings?

only thing i changed from default was the GPU preview, going to try the CPU

#

looks fine for me.
Please try to increase max lightmap size to 2048.

Im just wondering, why the light is bleeding through the walls there onto the ground

#

Is there space below the walls so the light can shine below the walls?

#

thanks im giving it a try now, and i tried putting the walls through the ground and still had the same effect as that was my inital thought. is verry odd

#

make sure that the walls are casting shadows

#

not only that also make sure that the light source that you are baking has shadowcasting enabled

#

rapid barn make sure that the walls are casting shadows

they do, you can see that the light is different at the window

#

i thought the same first

rapid barn Apr 17, 2024, 7:46 PM

#

I didnt see you guys checking for shadowcasting

winter thunder Apr 17, 2024, 7:46 PM

#

Are your walls thick or just a 2D plane?

true plume Apr 17, 2024, 7:47 PM

#

they are 3D and apparently my light sources do not have baked shadows enabled so @rapid barn was correct. but this also dosnt make sense because why where my window shadows baking

rapid barn Apr 17, 2024, 7:48 PM

#

do you have multiple light sources?

true plume Apr 17, 2024, 7:48 PM

#

thanks for the help guys seems alright now

true plume Apr 17, 2024, 7:48 PM

#

rapid barn do you have multiple light sources?

only had 2 with the default settings

rapid barn Apr 17, 2024, 7:49 PM

#

so 2 light sources, one that has showcasting enabled, and the other one without any

winter thunder Apr 17, 2024, 7:49 PM

#

Lol. yeah i thought it didnt make sense with shadows, because the window throw shadows 😄

true plume Apr 17, 2024, 7:49 PM

#

yeh i assumed that they had it enabled because of the window. so my bad lol

#

that doesnt mean kjarudi is entirely wrong though, he mentions another point also to watch out for if you are seeing light bleeding

#

that being if you have too low of texel density or lightmap resolution for the walls/floor, those can be a possible source of leaking

#

although that doesn't seem to be your problem in this scenario

#

but anyhow good you have it solved, just a couple of things to watch out for

thanks for the tips, quite new to baked lighting and HDRP so is good to know
