Unexpected Material change/transparency when switching between ShaderGraph and material at runtime in HDRP

-

Reproduction steps:
1. Open the attached “IN-101574.zip” project
2. Open the “OutdoorsScene”
3. Enter Play mode
4. Observe the Quad material in the Game view
5. Press “T” on the keyboard
6. Repeat the 4th and 5th steps
7. Observe the Quad material

Expected result: The material remains white/not transparent
Actual result: The material turns transparent/gray

Reproducible with: 2022.1.0a1, 2022.3.62f1, 6000.0.48f1, 6000.1.3f1, 6000.2.0b1

Reproducible on: Windows 10 (User reported), Windows 11
Not reproducible on: no other environment tested

Notes:
- Pressing “T” switches between “Material 1” and “Shader 1” referenced on the “LoadObjectRuntime” GameObject, and switching back from “Shader 1” to “Material 1” produces the problematic behavior
- Could not reproduce with URP, only reproducible with HDRP
- Also reproducible in the Player

  1. Resolution Note:

    It seems like you are not setting up your dynamically created materials correctly. When you change the underlying shader, you are creating a new material instance that does not have the same properties. The properties cannot be copied because it is not the same underlying shader. You need to setup all the material properties again if you change the underlying shader.
