Are you experiencing issues with Live Unwrap in Blender 2.93.4? If you've turned off the feature, but adding or deleting seams causes the mesh to instantly re-unwrap, you're not alone. In this article, we'll delve into the possible causes and provide a step-by-step guide to help you resolve this issue.

Understanding Live Unwrap

Live Unwrap is a powerful feature in Blender that allows you to unwrap a mesh in real-time, making it easier to work with UVs. However, when it's turned off, you might expect the mesh to behave normally. But, as you've experienced, adding or deleting seams can cause the mesh to re-unwrap, which can be frustrating and time-consuming.

Possible Causes

Before we dive into the solutions, let's explore the possible causes of this issue:

Inconsistent UV data: If the UV data is not consistent across the mesh, Live Unwrap might not work as expected.
Seam settings: The seam settings might be causing the mesh to re-unwrap when seams are added or deleted.
Mesh topology: The mesh topology might be causing the issue, especially if it's complex or has many seams.
Blender settings: Blender's settings, such as the Live Unwrap threshold, might be contributing to the issue.

Step-by-Step Troubleshooting Guide

To resolve the issue, follow these steps:

Step 1: Check UV Data Consistency

Select the mesh: Select the mesh that's causing the issue.
Go to Edit Mode: Press Tab to enter Edit Mode.
Select all UVs: Press Ctrl+A to select all UVs.
Check UV data: Check if the UV data is consistent across the mesh. If it's not, you might need to re-unwrap the mesh or fix the UV data.

Step 2: Check Seam Settings

Select the mesh: Select the mesh that's causing the issue.
Go to Edit Mode: Press Tab to enter Edit Mode.
Select a seam: Select a seam that's causing the issue.
Check seam settings: Check the seam settings, such as the seam type and the seam direction. If the settings are not correct, adjust them accordingly.

Step 3: Check Mesh Topology

Select the mesh: Select the mesh that's causing the issue.
Go to Edit Mode: Press Tab to enter Edit Mode.
Check mesh topology: Check the mesh topology, especially if it's complex or has many seams. If the topology is causing the issue, you might need to simplify it or re-unwrap the mesh.

Step 4: Check Blender Settings

Go to Preferences: Press Ctrl+Alt+P to open the Preferences window.
Select the Live Unwrap tab: Select the Live Unwrap tab.
Check the threshold: Check the Live Unwrap threshold. If it's set too low, it might cause the mesh to re-unwrap when seams are added or deleted.
Adjust the threshold: Adjust the threshold to a higher value if necessary.

Step 5: Reset Live Unwrap

Go to Edit Mode: Press Tab to enter Edit Mode.
Select the mesh: Select the mesh that's causing the issue.
Go to the UV/Image Editor: Press Ctrl+Shift+Tab to open the UV/Image Editor.
Select the Live Unwrap button: Select the Live Unwrap button.
Click the Reset button: Click the Reset button to reset Live Unwrap.
