Texture Mesh with Trellis2: generated asset is registered correctly but never linked to its card (Cards_Assets)

[grugeth]

Summary

Running "Texture Mesh with Trellis2" produces a correct, fully-textured mesh and correctly records it as an Asset in the local database — but the resulting asset is never linked to the card it belongs to, so the UI falls back to displaying the original source image instead of the generated mesh.

Steps to reproduce

1. Have a card with a source image and (optionally) a prior mesh output.
2. Run the "Texture Mesh with Trellis2" action on it.
3. Wait for completion.
4. Open the card — the newest item shows the source PNG again instead of the new textured mesh.

What I found investigating app.db

The generation actually succeeded completely:

• A correct Assets row was created (e.g. id 53, name "Laughing Crying Emoji Mesh", assetTypeId=2), with fully accurate metadata:

  {
    "resolution": "Unknown",
    "format": "GLB",
    "source": "COMFYUI",
    "provider": "ComfyUI",
    "workflowId": 5,
    "workflowName": "Texture Mesh with Trellis2",
    "promptId": "cb3b0dda-6b22-41d1-a305-d7408bf0e5f2",
    "outputNodeId": "12",
    "outputFilename": "3DGenStudioTexturedMesh_00001_.glb",
    "savedOutputs": 1,
    "cardId": "2a54d580-3a70-49c3-b167-fbce15b62e93"
  }

• The promptId matches ComfyUI's own /history exactly, and node 12 is Preview3D — the correct output node.
• The referenced file (data/assets/meshes/<...>.glb) exists on disk and is byte-identical to ComfyUI's own output file for that prompt (21,276,048 bytes, verified).

But: there was no corresponding row in Cards_Assets linking this new asset to its card (cardId from the metadata, id 8 in this case). The card's Cards_Assets entries stopped at the prior two items (source image + earlier mesh); the newly generated, correctly-recorded textured mesh was simply never appended.

Fix applied locally as a workaround

INSERT INTO Cards_Assets (cardId, assetId, position) VALUES (8, 53, 2);

After this, the card correctly shows the textured mesh.

Suggested fix

Whatever step creates the Assets row and its metadata.cardId after a workflow finalization succeeds should also insert the corresponding Cards_Assets row (at MAX(position)+1 for that card) in the same transaction/step — right now that step appears to be silently skipped or failing independently of the (otherwise fully successful) asset creation.

Environment

• 3D Gen Studio v2.3.0 (Windows)
• Related to, but distinct from, the glb_path issue reported in Texture Mesh MultiView with Trellis2: glb_path never gets populated when a Source Mesh is selected #23 — that one is about a load failing before generation; this one is about a successful generation's result never getting attached to its card.

Hi.

I tested it right now in a Graph project, and it works for me, I don't have this issue:

I tested it in a Kanban project, and it works too, so I don't understand the problem:

In a Kanban project, there are some arrows to see all assets linked to a card.
