+    - **Multiple Images:** If you need to feed in more than one image, use the **core ComfyUI Batch Image node**.  
+        - This lets you route multiple images into LayerForge.  
+        - You can then stack, arrange, and edit them as separate layers inside the canvas.
+  - **Mask Input (optional):** Accepts a single external mask.  
+    - When provided, the mask is applied directly to the **output area** of the LayerForge canvas when `Run` is triggered in ComfyUI.

+    - **Composite Image:** The final flattened result of your layer stack.

-### `node_id` not auto-filled → black output
+#### ○ Incompatibility with Modern Node Design (Vue Nodes)
+> This node is **not compatible** with the new Vue Nodes display system.  
+>  
+> 🔧 **How to fix:**  
+> Go to **Settings → (search) "Vue Nodes" → Disable "Modern Node Design (Vue Nodes)"**.
 
-In some cases, **ComfyUI doesn't auto-fill the `node_id`** when adding a node.

-As a result, the node may produce a **completely black image** or not work at all.
 
-**Workaround:**
+#### ○ `node_id` not auto-filled → black output 
-
+> In some cases, **ComfyUI doesn’t auto-fill the `node_id`** when adding a node.  
-* Search node ID in ComfyUI settings.
+> This may cause the node to output a **completely black image** or fail to work.
-* In NodesMap check "Enable node ID display"
+>
-* Manually enter the correct `node_id` (match the ID Node "LayerForge" shown above the node, on the right side).
+> 🛠️ **Workaround:**  
+> - Open **Settings → NodesMap → Enable "Show node IDs"**  
+> - Find the correct ID for your node *(match the ID Node "LayerForge" shown above the node, on the right side)*.
