I added all the diffusion profiles of

[thin hazel]

Hey. I'm not sure. What are the HDRP diffusion profiles? Was this happening before adding them?

[wise mountain]

Im not sure. I added all of the diffusion profiles which I'm using. I added each and every one of them. It happened before adding them too I think, which is why I checked if I had all of them

I imported the terrain data from a URP project, as Im switching to HDRP

[thin hazel]

What are the dark areas on the Terrain? Is that where no Terrain Layers have been painted?

[wise mountain]

I think it's where a terrain layer is missing. But I'm not sure. I have all the textures which I used in URP also in HDRP (I'm 90% sure), so idk why it's black. It should just have a texture, but it could very well be linked to the weird black screen

[wise mountain]

@thin hazel do you have any idea of what else it could be?

[thin hazel]

No idea but I'm not givin up!

Are you using version control or able to make a backup of the project? I'm gonna start asking about modifying aspects of it and I don't want you to lose your work.

[wise mountain]

I haven't, but I can easily duplicate the project. I've been using that method previously too lol

*Only * takes like 40gb

[thin hazel]

haha. sorry

once you do that, im curious if 1. you still have the issue and 2. if you remove those weird terrain layers, does the issue resolve

[wise mountain]

The problem is that the "weird" terrain layers on the terrain are black, but in the inspector under Terrain painting tab it doesn't show those layers. All the shown layers just look fine and if I click them they reference the actual textures used which are also in my project

I'll also try deleting the Library folder when I have time open the project

Maybe thatll help

[wise mountain]

I deleted all the terrain layers on the terrain tiles that had the black texture. Glitch seems to be gone now

@thin hazel

Sorry for the late response btw, I was very busy

[thin hazel]

No worries! Thanks for checking. I'm not entirely sure why those Terrain Layers would have that effect in the viewport

If they were upgraded from URP, then they'll have different formats for the Mask texture but I don't see why that'd cause these issues

unless maybe it is generating NaNs from smoothness and really messes with some Exposure post effect you might have on a CustomPass volume in your scene

[wise mountain]

I made a new terrain palette layer, assigned it to all terrains, painted all the terrains with a texture that actually exists, and it seems everything's fine now. No weird errors too. I'll come back to this thread if something goes wrong again (which is likely lol)

Thanks for the help btw!
