Using 1.07.07 in UE4 4.10.4 on PC. In UFMODBlueprintStatics::EventInstanceSetParameter, EventInstance.Instance-\>setParameterValue is returning FMOD\_ERR\_EVENT\_NOTFOUND. EventInstance.Instance-\>isValid() returns true. The parameter name is correct. The parameter value is in range. What can we do to figure out what’s causing it to fail?

That error is returned if no parameter of that name exists. Double check the event has a parameter of that name.

If you are sure the parameter exists, and it still returns errors, if you supply banks + a studio api capture, then we can dig into what it is occurring.
