+            ## Tips
+            - Extremely large camera movement from the input view might cause low performance results due to the unexpected deviation from the training distribution, which is not the scope this model. Instead, you can feed the generation result for the small camera movement repeatedly and progressively move towards the desired view.
+            - 3D viewer might take some time to update especially when trying different images back to back. Wait until it fully updates to the new image.
