Exposed Properties values in Material do not update when changing values in the Shader Graph

Unity: ShaderGraph

Won't Fix

6.4.X

6.3.X

6000.3.0a5 onwards

Materials default initialize their property data based upon the default values in the shader. If the shader changes, those default values are not expected to propagate to the Materials that use them. Shader Graph does import a read-only material that keeps these default values up to date. While we don't necessarily recommend using this material for production, it can be used to setup material variants or for a more interactive debugging experience within a live scene.

Reproduction steps:
1. Open the attached “BugRepro” project
2. Open the “Assets/Graphics/Materials/JetStream.shadergraph“ Shader Graph
3. Select the Emmision property in the Blackboard panel of the Shader Graph
4. Change its Default value to 3, Min value to 0, and Max value to 5
5. Save the Shader Graph (Ctrl+S)
6. Select the “Assets/Graphics/Materials/JetStream.mat” material
7. Observe the material Exposed Properties in the Inspector window

Expected result: Default, Min, and Max values are updated
Actual result: Default, Min, and Max values do not update and still show the previous values

Reproducible with: 6000.3.0a5, 6000.3.0b6, 6000.4.0a2
Not reproducible with: 6000.3.0a4, 6000.0.60f1, 6000.2.8f1

Reproducible on: Windows 11
Not reproducible on: No other environment tested
