Question Progressive GPU Error : Failed to add geometry for mesh 'stud'; mesh is missing required attribute(s

Hell everyone,

I have some problems with the Progressive GPU lightmapping:

When I start to generate lighting with Progressive GPU the error

OpenCL Error. Falling back to CPU lightmapper. Error callback from context: CL_INVALID_PRO

occurs several times and the lightmapper in the Lighting settings changes to Progressive CPU.
When I then switch it back to the GPU lighmapper and click on generate lighting I get the following error message and the lighmapping stops at "preparing bake".

[PathTracer] Failed to add geometry for mesh 'Cylinder'; mesh is missing required attribute(s). Please make sure the mesh contains at least positions, normals and texcoord0.

I tried several things to solve the problem:

1.) Find the "Clyinder" in my Scene. Because there was nothing wrong with it, I deleted it from the scene and tried baking the light again. Still the same error message.

2.) I opened another scene from my Project and tried it there. Stil with the same result.

3.) Started a completely new Project, ( from the Unity hdrp template ) and still i got those errors. But this time it is 'stud' instead of 'Cylinder'.

4.) Uninstalled and updated unity

here some further informations:

I use the HDRP.
Progressive CPU seems to work fine.
The version of unity was 2019..4.6f1 and i updated to 2020.1.6f1.
I use a Nvidia 1070 GPU, with the laest river installed.

Some days ago Progessive GPU just worked fine.

I hope i gave all necessary information.

Thanks for your Help

 

I have this problem with both versions 2019.4.6f1 and 2020.1.6f1
But on 2019.4.6f1 it worked fine till yesterday.
I just reproduced the issue using the Universal Render Pipeline (2020.1.6f1)

Okay I will file a bug report after I made sure that it is an actual bug and not something that happens due to me doing something wrong.

 

Have the same

 

Hello @ADufay, thanks for answer!
If I will be able to reproduce this error, I'll post more details here

 

I got just this error: [PathTracer] Failed to add geometry for mesh '1_MD_LOW_0'; mesh contains non-finite values.
Unity 2020.2.3f1.

Still no idea how to reproduce this error

 

Unity 2020.2 is killing me with these lighting bugs. I'm also getting this, and a spamming of other errors when trying to bake a particular scene, which baked just fine in 2018.

In addition to:
[PathTracer] Failed to add geometry for mesh 'Bowl of Lemons'; mesh contains non-finite values.

These four errors spam forever over and over.
Line 215 in Verify - Geometry geom 0bbf78ae58547087ca378406dcd837eb: Index 0 has value 0 that reads non-finite value nan in channel 5, element 0

Reported my bug... case #1318450

 

Same here.

using 2019.4.23f1, trying to bake lightmap and keep showing errors like this

 

And backport for Unity 2020.3.2f1 LTS version? In my case I'm using URP

 

We had the same issue and found out that our created mesh (pro builder) had some strange uv coords (NAN). So we added a short fix and we got rid of the error above. Just use the following editor script to fix the issue (make a backup of your mesh first) and select the gameObject with the mesh in question and execute the following command(s):

Code (CSharp):

1. [MenuItem("ProBuilderHelper/Check and fix mesh")]
2. private static void CheckAndFixMesh()
3. {
4.    //Fix uv issues so that lightmapper can work!
5.    MeshFilter mf = Selection.activeGameObject.GetComponent<MeshFilter>();
6.    Vector2[] verts = mf.mesh.uv;
7.    bool assignBack = false;
8.    for (int i = 0; i < verts.Length; i++) {
9.        if ((float.IsNaN(verts[i].x)) ||
10.            (float.IsNaN(verts[i].y)))
11.        {
12.            assignBack = true;
13.            Debug.LogError("Float error:" + i  + " v:" + verts[i].ToString("F4"));
14.            verts[i] = Vector2.zero;
15.        }          
16.    }
17.    if (assignBack) {
18.        Debug.Log("Fix mesh!");
19.        mf.mesh.uv = verts;
20.    } else {
21.        Debug.Log("Mesh is ok!");
22.    }
23. }

Enjoy

 

Just amazing. This fixed my problems. Thank you!

 

Hello everyone.

I am having the same issue but I have a lot of GameObjects in my scene and from the error, I don't know how to identify which one it is in order to apply your code, @Zapan15 .

Does anyone have any suggestions on how to find it? @Pema-Malling @ADufay

[EDIT]

These are the errors:

Line 215 in Verify - Geometry geom f81e1dc919d514b7041e588d39cbb9a6: Index 0 has value 0 that reads non-finite value nan in channel 4, element 0

Line 229 in Verify - Geometry geom f81e1dc919d514b7041e588d39cbb9a6: 1044 components out of 63660 total are non-finite

[PathTracer] Failed to add geometry for mesh 'pb_Mesh99780'; mesh contains non-finite values.

[EDIT 2]

Fixed it by doing what is suggested in both of this posts:

Unticking contribute to global ilumination and the other steps.

 

I had the same problem, you can solve it by checking this option. I hope I helped you.

 

If this happens with Probuilder Objects, selecting all Faces on the faulty Mesh and "Rest UVs" via the UV Editor worked at least for me. Migrated a old Project and rund in the same error on CPU and GPU Baking.

 

Saved me, thx !

 

Thanks so much.

 

Sorry to necro, but I'm on 2021.3.23f1 and getting this error... Unity's lightbaking is atrocious, so many issues...

 

Alright, ill file one. I actually used to be able to bake on "Enlighten" but now i'm completely unable to bake no matter what setting i choose. I tried the above solution of turning "Generate Lightmap UV" to every model and it did nothing



Ill file a report, but here's the errors i'm getting if you have any insight. Baking does not move forward no matter how long i wait, this is after i had it baking for maybe a minute.

 

I followed and it works, thank you
