Vector Parameter changing doesn't work

I’ve created a dynamic material instance to change a vector parameter value ingame, but it doesn’t work.

Thank you for help:)

i would guess that the issue is that you care creating the instance but your not telling the mesh to use it. basically your creating a material but not applying it to the mesh. in any case you will need to reference the mesh that your looking to change the material on.

Thank you for your answer. I checked the code again and found the solution…thanks for the hint.
