I needed to find the solution for the same thing. It was challenging but I decoded that previous message from @Black_Phoenyx .
Might be useful for others if looking for this:
- Go to Construction script.
- Out of Decal component create “Create Dynamic Material Instance”.
- From the return value of it create “Set Vector Parameter Value”.
- Of course your material assigned to the Decal needs to have the property named same as “Parameter Name” so you can set this param dynamicaly.
