# Plan to Resolve ISSUE-011: Blender nodegroup script creates empty assets for skipped items

**Issue:** The Blender nodegroup creation script (`blenderscripts/create_nodegroups.py`) creates empty asset entries in the target .blend file for assets belonging to categories that the script is designed to skip, even though it correctly identifies them as skippable.

**Root Cause:** The script creates the parent node group, marks it as an asset, and applies tags *before* checking if the asset category is one that should be skipped for full nodegroup generation.

**Plan:**

1.  **Analyze `blenderscripts/create_nodegroups.py` (Completed):** Confirmed that parent group creation and asset marking occur before the asset category skip check.
2.  **Modify `blenderscripts/create_nodegroups.py`:**
    *   Relocate the code block responsible for creating/updating the parent node group, marking it as an asset, and applying tags (currently lines 605-645) to *after* the conditional check `if asset_category not in CATEGORIES_FOR_NODEGROUP_GENERATION:` (line 646).
    *   This ensures that if an asset's category is in the list of categories to be skipped, the `continue` statement will be hit before any actions are taken to create the parent asset entry in the Blender file.

3.  **Testing:**
    *   Use test assets that represent both categories that *should* and *should not* result in full nodegroup generation based on the `CATEGORIES_FOR_NODEGROUP_GENERATION` list.
    *   Run the asset processor with these test assets, ensuring the Blender script is executed.
    *   Inspect the resulting `.blend` file to confirm:
        *   No `PBRSET_` node groups are created for assets belonging to skipped categories.
        *   `PBRSET_` node groups are correctly created and populated for assets belonging to categories in `CATEGORIES_FOR_NODEGROUP_GENERATION`.

4.  **Update Ticket Status:**
    *   Once the fix is implemented and verified, update the `Status` field in `Tickets/ISSUE-011-blender-nodegroup-empty-assets.md` to `Resolved`.

**Logic Flow:**
