4K Texture looks blurry and normal / roughness do not work

[NoTitleGamesOfficial]

I have the same 4K Texture (with Roughness & Normal Map) attached to a cube and the hterrain. As you can see it looks better on the cube:

On the Terrain, the normal and roughness map is missing and the ground looks blurry:

These are my import settings:

Every help is appreciated :)

The issue seems to be in common with your solution from this issue:
#404

When i select "Classic 4" as shader, instead of custom, the normal/roughness map work.

Any idea how to solve both issues?

Classic4Lite does not support normalmapping. You have to choose a shader (or fork and modify one) that supports them, such as Classic4.
Note that if the only thing you wanted to modify was the thing in #404, you can now change to Classic4 instead of Custom and modify the specular parameter (you need the latest version in the repo tho, otherwise you have to fork like in the issue).

Also I don't see any blurryness on your screenshot, the texture is probably just scaled up more I guess. The cube's UV-mapping is quite arbitrary to whatever Godot defaults to.

Hi, I have the same problem. Using a texture with a normal map, but the terrain looks very flat. I see your comment on changing the specular parameter, but I cannot find it anywhere in the inspector setting for the Classic4 shader. What am I missing?

Make sure you're using a shader that supports normalmaps, otherwise your normalmap won't be used.

About the specular option:

Note that specular isn't really related to the "strength" of normalmapping, it only makes stuff more shiny-ish.

I'm testing normalmaps right now in Godot 4.2.2, and I don't know if it's my scene that has gone too old, but normalmapping with MultiSplat16 seems broken. I don't know how that happened considering it used to work in the past and that I barely even touched the shaders in the past year :(
It's not as broken with other scenes, so I wonder what is going on.
Edit: looks like my packed textures are to blame, no clue why it's all red. Repacking them fixes it.

Classic4 should support the normal map, right?

[Zylann]

Yes it should. Just testing it right now and works fine
