Spawn a dynamic decal material instance at position.


I am trying to create a dynamic decal material (to change its “Opacity” parameter at runtime) and then “spawn decal at location” using it.

Here is the construction script that create an instance of material, set its parameters and promote it as a variable:

And here is the way I pop the material into my world (NOK is the one that does not work):

Any idea why nothing appears when it is dynamic ?
