 ### Core Nodes
 
 - **👀 SBS V2**: The main node. Input a 2D image, get a 3D SBS image + depth map.
-    - `depth_scale`: Intensity of the 3D effect.
-    - `mode`: Cross-eyed vs Parallel.
-    - `highsodium_optimization`: Enable vectorized algorithm for faster processing (may produce slightly different results).
