## Importing
### Wolvenkit finds too many vertices, but Blender export is fine!
The [wolvenkit-blender-io-suite](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/modding-tools/wolvenkit-blender-io-suite "mention") will check all your meshes against the vertex limit (\~65k) before exporting. However, under certain circumstances, Blender's default export shatters your plugin into a million parts. **This is not the plugin's fault**!
#### Delete custom normal split
You can check if your mesh has any custom `split normal` attributes, and delete them.
{% hint style="danger" %}
As this will irrevocably change your 3d object, create a **backup** first.
{% endhint %}
#### Check your UV splits
The GLTF algorithm **really** doesn't like it if two vertices have the same UV coordinates (see [this ticket](https://github.com/KhronosGroup/glTF-Blender-IO/issues/912)).
Here's how you can fix it:
1. Select the overlap
2. move the overlap out of the UV editor's box (it will tile, so everything is fine)\
Shortcut: `g` -> `x` -> `1` or `g` -> `y` -> `1`
3. Profit
### My import won't show up in-game!
We need to troubleshoot your **import**.
#### Does the Wolvenkit preview update?
Yes: The problem is somewhere else, the mesh import works fine.
No: [#is-there-an-error-message-in-the-console](#is-there-an-error-message-in-the-console "mention")
#### Is there an error message in the console?
Yes: Here's where your problem is. Make the error message go away by checking the rest of this guide.
No: [#do-you-have-extra-shapekeys](#do-you-have-extra-shapekeys "mention")
#### Do you have extra shapekeys?
In Blender, check your shapekey section. It should look like the green box (or be empty).
If it does not, you need to **apply** any extra shapekeys, because Wolvenkit will ignore them on reimport. Expand the box below, or check [here](https://wiki.redmodding.org/cyberpunk-2077-modding/modding-tools/wolvenkit-blender-io-suite/wkit-blender-plugin-akl-autofitter#modifier-cannot-be-applied-to-a-mesh-with-shapekeys) to find out how.
Get the edit out of the shapekeys
Do the following things:
1.
```
```
2. Duplicate your mesh: Select it in Object Mode, then press Shift+D
3. Click the arrow under the `-` button next to the shapekey box
4. Click `New Shape from Mix`
5. Now, delete all the **other** shapekeys (select them and click `-`)
6. Delete your new shapekey as well. That will **apply** it.
7. In Object Mode, select the duplicate of your mesh (that still has all the shapekeys)
8. Delete your additional shapekeys. That will reset it to an un-refitted shape. We want only the game ones here!
9. Go to Edit Mode (hotkey: `tab`)
10. Select all vertices (hotkey: `A`)
11. Delete all vertices (hotkey: `X`)
12. Go back to Object Mode (hotkey: `tab`)
13. Select your shapekey-less refitted mesh
14. Select your empty mesh
15. Join them together (hotkey: `ctrl+J`)
If everything went well, you should now have a mesh with Wolvenkit-compatible shapekeys!
### Tangents
You get an error message like this:
`Message: One or more Geometry in provided GLTF doesn't contain Tangents data. Tangents must be included within glTF files.`
#### Use the Cyberpunk Blender IO Plugin to export
Quick, easy, recommended: the plugin will tell you exactly what's broken and how to fix it. Download it [here](https://github.com/WolvenKit/Cyberpunk-Blender-add-on/releases).
Alternatively, you can check by hand:
Expand if you like to suffer
1. Check if your mesh is **triangulated**. If you aren't sure whether or not it is, go into edit mode, select everything, and go to Face -> Triangulate (Shortcut: Ctrl+T)
2. Check your export settings and make sure that you have the correct box checked upon export:\
3. If the error persists, check that each of your submeshes has an UV map:\
\
If not, you have to create one (and probably UV unwrap your mesh).
## Importing: bone troubles
### Bones not found in import mesh(es)
The armature you created in Blender has more bones than the mesh you're trying to import into. Since Wolvenkit can't create these bones (yet? Mesh import/export is hard), you're seeing an error message.
To get rid of it, delete the bones in Blender, or import into a different mesh (see [#fixing-bone-troubles](#fixing-bone-troubles "mention") as for how)
### Bone: neutral\_bone not present in export Rig(s)/Import Mesh
The neutral bone is created by the glb export plugin when there are vertex groups without a parent bone. WolvenKit will not let you import if there is a mismatch.
{% hint style="info" %}
Your armature in Blender needs to have a bone for every vertex group in the submesh, and there must not be vertices with no vertex group assigned.
You then need to import over an [already-existing .mesh file](#option-2-the-netrunner-suit) which supports all those bones.
{% endhint %}
### But the add-on let me export!
Then some vertex groups had vertex weights so small that Blender rounded them down to 0.
Import the exported `.glb` file and run the checks again — some verts will have no weight now, and you can fix them.
### Fixing bone troubles
The following two scripts help you finding and/or fixing the problem. Switch to the Blender Scripting perspective and create a new, blank text file. Then, toggle the Blender system console to see their output (Blender: Window -> Toggle System Console)
**Missing bones**
**Optional:** To find which bones you're missing, you can use [this script](https://gist.github.com/manavortex/080d04065ee4c45aaad1e7c221db68c9), which will print their names to console. You can also skip this step and try the troubleshooting below.
**Vertices without weights**
You can use the [wolvenkit-blender-io-suite](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/modding-tools/wolvenkit-blender-io-suite "mention")'s [#mesh-tools](https://wiki.redmodding.org/cyberpunk-2077-modding/modding-tools/wolvenkit-blender-io-suite#mesh-tools "mention") to `Group Ungroup Verts` — if you're lucky, that will solve the problem.
#### Option 1: Fuck those bones: Python
You can find a [Python script on mana's github](https://github.com/manavortex/cyberpunk2077/blob/master/python/armature_cleanup/armature_delete_unused_bones.py) that will drop unused bones and vertex groups. Run it in Blender's Scripting Perspective with your meshes selected.
#### Option 1: Fuck those bones: Noesis
You can [import the mesh with Noesis](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/exporting-and-importing-meshes#noesis-.fbx-2), which will not do any of these checks. For that, you need to import/export via .fbx.
{% hint style="warning" %}
Since noesis expects differently-named submeshes under the root armature, you'll want to export the mesh via noesis, join your changed meshes on those under Noesis\_Root, and import it again.\
**Caution:** You'll have to rotate your armature in this case.
{% endhint %}
{% hint style="danger" %}
While this will get your mesh into the game, the missing bones mean that parts of it won't move the way you expect it!
{% endhint %}
#### Option 2: The Netrunner suit
The armature from the following mesh has a lot of bones and will often resolve most of your issues:
```
t0_005_pwa_body__t_bug.mesh
t0_005_pma_body__t_bug.mesh
```
Try using the Netrunner body as a base for import. You can use Wolvenkit's [Import/Export: Mesh (3d Model) #Select base mesh](https://app.gitbook.com/s/-MP_ozZVx2gRZUPXkd4r/wolvenkit-app/usage/import-export/models#select-base-mesh "mention") feature for this.
{% hint style="info" %}
To create more submeshes, you can either
* Try the [Import/Export: Mesh (3d Model) #Preserve Submesh Order ](https://app.gitbook.com/s/-MP_ozZVx2gRZUPXkd4r/wolvenkit-app/usage/import-export/models#preserve-submesh-order "mention")import setting
* create more submeshes with the correct naming in Blender, e.g. `submesh_01_LOD_1`, `submesh_02_LOD_1`
{% endhint %}
If you end up with missing bones,
#### Option 3: Transferring bones
It's time to play 3d puzzle and assemble bones from multiple sources. Unfortunately, there is no simple solution for this yet. You need to
* find the bones that your armature is missing in other meshes
* transfer them into your import target mesh (guide on [xbae's page](https://xbaebsae.jimdofree.com/cyberpunk-2077-guides/cp2077-transferring-and-expanding-skeletons-in-meshes/))
* export all the extra meshes into Blender
* [merge their rigs](https://github.com/Simarilius-uk/CP2077_BlenderScripts/blob/main/Merge_rigs.py), which you should do with the linked Python script
* and finally reimport everything back into Cyberpunk.
## Importing: Everything else
WolvenKit will not import a mesh that has any kind of issues. Those include, but are not limited to:
* non-flat faces
* zero faces/edges
* loose vertices/edges
**There is no guarantee that any of the steps below will actually solve your problem.**
#### **Edit Mode**
In Edit Mode, you can find a few commands in the Mesh -> Clean Up menu:
* Delete Loose
* Split Non-Planar Faces
* Split Concave Faces
* Merge By Distance\\
{% hint style="warning" %}
If you select your whole mesh, **Merge By Distance** will merge the individual parts, obliterating the seams. To avoid that, make sure to do them one after another:\
\- Select a vertex/edge/face in Edit Mode\
\- hold down Ctrl Num+ to select everything connected\
\- use Merge By Distance before proceeding to the next part of your mesh
{% endhint %}
#### It's still broken
Your last option is the [3d print tool](https://docs.blender.org/manual/en/4.0/addons/mesh/3d_print_toolbox.html) to (hopefully) find out what is wrong with your mesh.
Fortunately, the tool is free, easy-to-use and already included in your Blender.
{% hint style="info" %}
If you don't have a 3d print entry in the tools of your 3d viewport, you might need to enable the plugin in Blender's settings first.
{% endhint %}
Use the 3d print tool in edit mode to directly fix your issues
* Zero Edges: Those are bad, fix them (click on them, then press X and just delete them)
* Non-Flat Faces: Those are even worse, as they can make the game crash. You need to split them up until they are flat, or investigate the surrounding edges/vertices to see what's going wrong here.
* Zero Faces: Only fix if you have <100 of them — the tool doesn't always identify them correctly (the mesh analyzed above was `h0_000_pwa_c__basehead`, which is absolutely fine).
## In-Game
### My mesh explodes!
This is most likely an issue with Garment Support. Please check the corresponding wiki page for troubleshooting, especially the part about [unique IDs](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/garment-support-how-does-it-work#my-garment-support-explodes-on-contact-with-another-item).
### My mesh won't show up
#### In Blender
* make sure that you have exactly one UV map
* check **Face Orientation** — most materials won't show backfaces (red). You can import submeshes with the suffix `_doubled` to make WolvenKit generate them for you, like it does with hair.
#### In Wolvenkit
When saving your mesh, check the console for errors. In version >= 8.9.0, a basic material validation is taking place.\
If you don't see any warnings, make sure that the resource paths in your mesh are correct and that you aren't loading invisible textures.
### Parts of my mesh are missing
Do they show up in the Wolvenkit preview?
* No: you probably forgot to select them when [exporting from Blender](https://wiki.redmodding.org/cyberpunk-2077-modding/modding-tools/wolvenkit-blender-io-suite/wkit-blender-plugin-import-export#exporting-from-blender). Make sure that you get them all into Wolvenkit.
* Yes: There's either an issue with your [material assignments](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/materials/materials-troubleshooting) or with your [chunkmasks](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/files-and-what-they-do/file-formats/3d-objects-.mesh-files/submeshes-materials-and-chunks). Refer to the corresponding guides to learn how you can debug this.
If that's not it, check [#my-mesh-is-inside-out](#my-mesh-is-inside-out "mention") below.
### My mesh won't move at all
Some meshes require an entAnimatedComponent along with the garment's component. Check [here](https://wiki.redmodding.org/cyberpunk-2077-modding/modding-guides/npcs/appearances-change-the-looks#animations-if-you-cant-avoid-them-copy-them-as-well) for details.
### Changes from Blender are missing in-game
For example, you have moved something, but the change doesn't show in the game: this most often happens when you change things around in edit mode, since they are stored as object properties rather than applied immediately.
1. Select the object in edit mode
2. Press Ctrl+A
3. Select "All Transforms" to apply all transformations.
### My mesh is moving weirdly
E.g. you've changed a shape, but now everything moves at an offset.
As stated in the [importing/exporting guide](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/3d-modelling/exporting-and-importing-meshes), it is easy to fuck up the mesh's properties, and this is most likely what happened. The easiest way to "fix" this is to apply your shape deformation to the original object.
#### Replacing the vertices
1. Import the original object into Blender, without any of your changes. If you have to, reexport the working file from Wolvenkit.\
2. See [#strategy-2-replacing-the-vertices](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/porting-3d-objects-to-cyberpunk#strategy-2-replacing-the-vertices "mention") on the [porting-3d-objects-to-cyberpunk](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/3d-modelling/porting-3d-objects-to-cyberpunk "mention") page
### My mesh is completely warped
If you have [added the item](https://wiki.redmodding.org/cyberpunk-2077-modding/modding-guides/items-equipment/adding-new-items) via [ArchiveXL](https://github.com/psiberx/cp2077-archive-xl) or [swapped out an in-game item](https://wiki.redmodding.org/cyberpunk-2077-modding/modding-guides/items-equipment/editing-existing-items/replace-a-player-item-with-an-npc-item) with something that belongs in a different slot (e.g. a jacket on the head slot), you might have to fix the corresponding entity file.
### My shadow mesh is always visible
Check the `renderMask` attribute inside `renderResourceBlob / header / renderChunkInfos / index`*.* For shadow meshes, there shouldn't be anything but `MCF_RenderInShadows`.
### My mesh ignores my texture edits!
The textures are most likely embedded. Here's how you can force your material to pull in external textures instead:
Thanks to Adahm for the screenshot
### My textures are black and shiny!
That's a problem with your **materials**, not with the mesh itself. Check [images-importing-editing-exporting](https://wiki.redmodding.org/cyberpunk-2077-modding/modding-guides/textures-and-luts/images-importing-editing-exporting "mention") -> [#troubleshooting](https://wiki.redmodding.org/cyberpunk-2077-modding/modding-guides/textures-and-luts/images-importing-editing-exporting#troubleshooting "mention")
## Garment Support
You can find this on its own page, [#troubleshooting-garment-support](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/garment-support-how-does-it-work#troubleshooting-garment-support "mention")
## My mesh is inside-out!
Check the [#face-orientation](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/blender-getting-started#face-orientation "mention") and make sure that all the faces you see are blue. If not, you have to flip them – see [the link](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/blender-getting-started#face-orientation) for how.
