Can you show the scene window lightmap debug view for UVs

heavy hound Oct 14, 2024, 3:14 PM

#

this one?

#

i really appreciate the help btw

blazing iris Oct 14, 2024, 3:15 PM

#

UV overlap also

heavy hound Oct 14, 2024, 3:15 PM

#

uv overlap shows nothing

blazing iris Oct 14, 2024, 3:16 PM

#

Texel validity?

heavy hound Oct 14, 2024, 3:17 PM

#

there's a bit of jank, mostly just in a spot where i forgot to delete an overlapping face

#

doesn't really correlate to the lightmap bugs visually

blazing iris Oct 14, 2024, 3:17 PM

#

Not significant enough to explain the weirdness anyway

heavy hound Oct 14, 2024, 3:18 PM

#

shadowmask seems fine

blazing iris Oct 14, 2024, 3:19 PM

#

Light overlap?

#

That seems like an excessive number of overlapping lights

heavy hound Oct 14, 2024, 3:20 PM

#

i do probably have too many lights here, could that be part of it?

#

i'm gonna try with as simple a scene as possible n go from there

blazing iris Oct 14, 2024, 3:23 PM

#

Shadowmask will bug out if more than 4 light ranges are overlapping

#

Even if the surfaces they illuminate would not overlap

heavy hound Oct 14, 2024, 3:25 PM

#

just using a cube imported from hammer with one light there's still that face offset

#

so definitely a hammer issue

#

UV chart is normal

blazing iris Oct 14, 2024, 3:28 PM

#

heavy hound so definitely a hammer issue

Is lightmap UV generation enabled for all the meshes in the scene in Unity?

#

In Unity's import settings I mean

heavy hound Oct 14, 2024, 3:29 PM

#

yeah

blazing iris Oct 14, 2024, 3:36 PM

#

I guess that points to that there's really something off with the meshes as they are imported

heavy hound Oct 14, 2024, 3:37 PM

#

that's what it looks like, i am also getting similar artifacts on a unity-created cube too

#

i'll try messing around in hammer maybe?

blazing iris Oct 14, 2024, 3:37 PM

#

Huh, if unity's default cube is also affected that would rule out the custom meshes as the cause

#

But confirm that by baking a scene that has only unity's default meshes

heavy hound Oct 14, 2024, 3:40 PM

#

i'll try that in a sec, but same thing for a cube made in blender too

#

it seems like it's generating good maps, then just offsetting the faces

#

lemme try doing this in a fresh scene actually

blazing iris Oct 14, 2024, 3:42 PM

#

Restart the editor while at it

heavy hound Oct 14, 2024, 3:47 PM

#

dude, fresh scene and it's perfect

heavy hound Oct 14, 2024, 3:47 PM

#

heavy hound i'll try that in a sec, but same thing for a cube made in blender too

exact same model import as this

heavy hound Oct 14, 2024, 4:12 PM

#

i couldn't tell you at all what the issue was but it just simply works now

blazing iris Oct 14, 2024, 4:42 PM

#

heavy hound dude, fresh scene and it's perfect

Many of my problems similarly get solved with "sanity checks" like that

heavy hound Oct 14, 2024, 5:43 PM

#

lol yeah, i gotta remember that
