I have been setting lots of different variables and other blueprint values in my Sequence, and all in all I really love the new system. However, we decided recently to make it start raining during the sequence, and have the environment get wet and drizzly as it rains. Since there are many blueprints comprising the map, most having their own material instances, my environment artist gave me a “Material Parameter Collection” which controls the wetness value in the master material that all of the instances are referencing. Is there any way to modify this in my sequence, since it is not an element within my map?
