+## 📝 DESCRIPTION
+
+The **View Texture Node** is a utility node used to visualize and manage the RGBA channels of a texture. It allows you to split the input texture into its individual color channels (Red, Green, Blue, and Alpha) and view them separately.
+
+### Features:
+- **Texture Input**: Accepts either a `Texture2D` or `ImageData`. 
+- **Channel Separation**: The node splits the texture into individual channels for viewing and manipulation.
+- **Texture View**: The node allows you to view the whole texture as well as individual channels (RGB, R, G, B, A) in the Unity editor.
+
+This node is ideal for cases where you want to debug or manipulate textures on a per-channel basis. You can also view the entire texture or view specific channels like Red, Green, Blue, or Alpha.
+
+### **How It Works**:
+1. **Process**: The `Process` method checks for the texture input, and if it’s not provided, it converts the `ImageData` to a `Texture2D`. The texture is then processed, splitting it into its RGBA channels.
+2. **Channel Textures**: The node generates textures for each individual channel (R, G, B, A), which can be viewed separately using the editor interface.
+
+This node is derived from [`BaseImageNode`](Nodes/BaseImageNode).

+
+## ⚠️ KNOWN ISSUES
+
+- Ensure that the input texture is properly loaded. If the texture is missing or corrupted, the node may not function as expected.
+- The `ImageData` input is optional, but if it’s provided, it will be used to generate the texture if the `Texture2D` is not connected.
