UNITY_PREV_MATRIX_M and UNITY_PREV_MATRIX_I_M errors are thrown when enabling GPU Instancing on a material
Reproduction steps:
1. Open the user's attached project
2. Select "Assets/Broken Graphs/New Shader Graph" Shader Graph
3. Notice there are no error messages
4. Select "Non Instanced Shader Working" material
5. Enable GPU Instancing
6. Select "New Shader Graph" again and observe the Inspector
Expected result: No errors are thrown
Actual result: 'UNITY _PREV_MATRIX_M' and 'UNITY_PREV_MATRIX_I_M' errors are thrown
Reproducible with: 12.0.0 (2021.2.0b9), 12.1.3 (2021.2.8f1)
Not reproducible with: 10.9.1 (2020.3.34f1), 12.0.0 (2021.2.0b8), 12.1.4 (2021.2.9f1), 12.1.6 (2021.2.19f1, 2021.3.2f1), 13.1.8 (2022.1.0f1), 14.0.2 (2022.2.0a13)
Couldn't test with: 7.7.1 (2019.4.37f1) (used Shader Graph breaks)
Note:
- user notes that after the errors appear, Shader Graphs become difficult to work with (some properties are not displayed and can't be set through script)
