Issues with URP/Lit (NEED HELP)

[quaint rune]

Notice the first picture Hazeem on the left is clean but he is URP/Unlit so he will never show any shadows. On the second photo Hazeem is URP/LIt and his face is disfigured. Spent about 3-6 hours troubleshooting. I tried cleaning him up in Blender twice Mixamo just rigged him wrong and Unity cant process him in the new upgrade.

Try removing the normal and metallic maps one by one.

[quaint rune]

I tried that it just goes gray.

[plush bay]

What goes gray?

Why would it go gray? You're not removing the albedo(base map) texture, are you?

[quaint rune]

Well not technically gray but I tried removing each one and it changed pigmentation. But the scars are still there even without the normal and metallic.

[plush bay]

Can you show what it looks like?

With both unassigned.

[quaint rune]

Sure. Give me a moment.

[quaint rune]

No Metallic and No Normal.

[plush bay]

It really looks like there are 2 meshes overlapping.

Can you screenshot the prefab hierarchy + the renderer inspector?

With the material category expanded.

[plush bay]

Not this... On the first screenshot there is a material category in the renderer settings. Expand that.

Also try moving to gameobject a bit to the side...

[quaint rune]

That list was from materials in rendering settings. I just forgot to open it on the first screenshot. For some reason my pc was glitching and not letting me take the full screenshot again only the opened materials menu

[plush bay]

That's the list of all the materials in the assets. That's not what I asked for... Read me previous message again.

But anyway, I can see that there's only one mat there. Try moving the gameobject to the side.

I was talking about this.
But it doesn't matter anymore

[quaint rune]

So that materials area it wont let me take a screenshot of everything with that open it only focuses on the category which I already sent

[quaint rune]

This is the character with no materials added. It is clunky and not smooth rendering like normal objects.

[rough moss]

Mesh normals are corrupted or screwed up otherwise
Recalculating normals from import settings might fix it

I've only seen this type of issue with meshes ripped from another engine so that's what I suspect as the cause

But it could be that you tweaked the mesh externally for some other reason first which caused the problem

Could also be related to bone weights or blend shapes, technically anyway since they can modify normals on a per-vertex basis
But not sure how that could occur

[quaint rune]

I went through recalculating normals twice on Blender. I even did other steps, Center Origin, Apply Modifier and Mirror, Merge Vertices.

[rough moss]

Does the error present itself on the mesh that you have not modified at all, and if so did you try Unity's import settings' import recalculation

Re-exporting a rigged mesh is likely to always break something because it's a lossy operation

Though the most important question is that is this a ripped or decompiled mesh to begin with

[quaint rune]

Well you seen how it looked when I chose Unlit it was clean. Just without proper shadows. Which will hurt realism later once I had animations.

[rough moss]

That doesn't indicate anything about the actual issue
Unlit looks fine because it doesn't rely on mesh normals for any lighting calculations, as it has no lighting calculations

[quaint rune]

What is a ripped or decompiled mesh? It seemed fine When I exported it to Unity.

[rough moss]

One that was exported into some 3D engine before being exported out of it again
Do you know where the mesh came from?
And if it seemed "fine" before was that using a Lit or Unlit material at that point, and what seemed to cause it be not fine

[quaint rune]

I created the image from my own art and made it 3D in Tripo. How do I even check on Tripo to see if the image is LIT or UNLIT? That would be a game changer I reckon.

[rough moss]

The material would be unlit (or lit, or using some other shader), which is what applies the texture (image) onto a mesh
If the mesh displays a texture or reacts to light (or both), it has some kind of material

[plush bay]

Again, this is not what I asked, but never mind.

Did you try moving the gameobject yet..?
I feel like you just have 2 overlapping GameObjects with the same mesh.

[rough moss]

Tripo apparently is an AI mesh generator
I would not trust it to generate correct normals, so you should verify what kind of normals the mesh comes out with directly from that program
Preferably checking the normals in Blender using blender's tools

Checking for overlapping meshes/geometry is a good call

[quaint rune]

That’s literally the material dropdown you underlined that comes up on the Rendering Mesh. I just explained it’s Unity is not letting me take the full screenshot with that drop down opened.

[plush bay]

No it's not. That's not the drop down. That's what opens up when you click the browse button next to a material slot.

[quaint rune]

I’ll have to look into doing that thanks!

[plush bay]

I can literally see 2 prefabs that seem to use the same mesh in your scene...

If they're on the same position, they would overlap like that.

[quaint rune]

Are you talking about just opening the material tab?

[plush bay]

Yes, that's what I was talking about. But as I said, it doesn't matter already.

[quaint rune]

You think they are overlapping? How can I check the hierarchy system is so confusing at first it’s not simple drag and click you have to find the files and extract stuff ugh 😑

It really looks like a shade is overlapping the object. But this only happens in URP/Lit

[plush bay]

What's the parent object that you don't have selected now? Can you select it and take a screenshot?

[plush bay]

For hierarchy system, I'd really recommend learning the basics of working with unity. It's a core aspect of unity and if you don't know how to work with it you're gonna fail hard. I recommend the beginner pathways on Unity learn.

[plush bay]

Okay.
Can you select all the objects in the scene aside from the one selected? Use Shift/ctrl + click.

Then if you hover on the left side of the hierarchy next to any object, there should appear an eye icon. Click it. Then take a screenshot.

[rough moss]

If the normals issue is in the mesh, it should appear when imported into blender

And in blender you can also check for overlapping geometry by selecting individual vertices or faces and moving them to see if there's more beneath

Overlapping objects in unity are a separate potential issue

but both are possible

[plush bay]

Yeah, I start thinking it's just extra geometry in the mesh itself.

[quaint rune]

So I should take it back to the blender you reckon?

[plush bay]

Yes. You can also try checking it in unity via frame debugger, but that might be a bit more complicated than blender.

[rough moss]

Also, since bone weights can technically mess up vertices, I'd pay attention if the issues appear before rigging or only after it

[quaint rune]

I need more help. This is not a rendering issue but with Animation and movement issue. I made a video showing my situation. https://www.youtube.com/watch?v=RvYbCA4HQq0

[ruby tendon]

That green plus icon, seems like it was added in unity. try disable/hide it, or I'd say delete it
