Terrain turn black after bake lightmap

[T4Totoro]

Hi there, i got an issue, that after bake lightmap in URP pipeline, my terrain seem display dark when nearby, and be normal when far away.

Can you help me with this issue?

There should be a far distance and a close distance for color you would need to adjust both.

this only happen after i bake lighting and apply to my scene, when i remove the lighting map data, it will appear normally.

Do i need to adjust anything?

What is your color map settings?

sorry but somehow i dont know how to check it, because our TA just leave the project, i'm basically just a 3D artist.

but i think the lightmap data somehow override something of GTS, here the scr eenshot of before and after having lightmap data in Scene

[Bryan]

Can you please tell me what the GTS Profile is. 
This almost looks like its the GEO Settings Farn Normal strength and other far settings vs the near settings. 


I would go through all the far settings Color map, Geo, and Height blending would be the most important here. 
What you can do is disable each section first to see what could cause that to happen. 
Then enable each one to see where that change is being made. 
If I had to guess it would be the GEO Settings.

hey @T4Totoro,

Can you please share your lightmap settings? 

It can be found under window -> Rendering -> Lighting and under the Scene Tab.

@Isaac thank you for reply me,

here is the screenshot:

Hi there, sorry that i missed your reply, so sorry,

I use Detail setting, Geo setting, Height and Variant, after recheck as you note, i notice that my terrain after baking lightmap, my terrain seem to be lose all normal and roughness, from all GTS setting and Texture layer paint on my terrain, only base color remain, so it make my terrain look dark and flat.

Hi @T4Totoro,

I tried your lightmap settings and GTS settings in a fresh project and can't seem to reproduce the same issue that you are experiencing.

Could also check if any of the textures within the GTS Material are missing?

They can be found by navigating to the terrain component whilst GTS is enabled, and selecting the material slot in the Terrain Settings tab. Check to see if any of the textures within the same folder as the GTS terrain material is not assigned in any slots within the material

[T4Totoro]

@IsaacThe material seem has texture connect correctly, here is screenshot that i try to bake preview.

Is there any chance that the texture compress or lightmap compress impact it?

And my terrain are separate into 4 pieces also.

[T4Totoro]

@Isaac i still need your help, please.

Hi @T4Totoro, sorry that this is still a problem. Could you confirming if this is still an issue in a fresh URP project with the same lightmap baking settings? 

You mention that the terrain is 4 separate pieces, is that 4 separate Unity Terrains, or 4 separate meshes (i.e. not Unity Terrain)?

Hi @Isaac, after checking and testing, we found out that this node from shader graph is the one that making my terrain turn black after baking:

If i turn off the nearCamera node, the terrain display ok.

If i turn it on with value 1, it will make my terrain be darken

 

And if i link the graph, my terrain seem darken from the center.

 

 But the problem is i only can edit the graph with the base shader but not the compiled one, which will have the shader effect. Can you help me with this?

[Isaac]

Hey,

Can you double check if the albedo color is different between the near and far blend? This can done through Window -> Analysis -> Rendering Debugger, in the Material section:

Can you also check if the Ambient Occlusion is drastically different between the 2 blends?

If it is darker than closer to the terrain, you could bias the ambient occlusion in the layers panel of the GTS Manager

[T4Totoro]

@Isaac Hey, I already recheck and the problem is solved now!

Thank you all for support me :3.

Thank you for the update!
