No visible change of dynamic material instance on mesh

[anonymous_user_308f0a98]

Thank you so much for the reply. I tried some test. I tried EmissiveColor and BaseColor for both Material element 0 (which is round AMD inner circle) and element 1 (which is white fan) and results are:

1. Color change happens for Material element 0 for both Base and Emissive color
2. No color change for Material element 1 for both cases

Also there is NO post processing in my level.
