AReverbVolume missing MinimalApi

We would like to spawn a Reverb Volume actor in C++ but can’t because it doesn’t export its symbols, and thus we can’t get the Class object of it without getting linker errors.

On a side note it looks like there are a good many actors that are missing the specifier. I would ask why this isn’t the default for actors? I can’t think of a case where you would have an actor that you don’t want to be able to spawn via C++.

Two things that I think may help a lot is to have someone at Epic go through the engine class and find any public actors or uobjects that are missing this specifier and add it whenever possible. Also it would be nice if you considered making it the default that a class which extends from Actor automatically gets the specifier from the header tool (if it is even possible for the header tool to know the inheritance tree).

Also if you can think of a way to spawn a ReverbVolume actor without the class having minimalapi until this can be added in, that would be a great help :).

Actually it is not fixed in the last versions. See here.

In this case we are closing the issue as a duplicate. I have assigned a technician to look into the question here:
