Is there any way to stimulate physics of object through Blueprints via Trigger volume?
Did you tried to use SetSimulatePhysics?
Yes but i want to use trigger volume to play a sound
For example i need to do drop a picture frame from the wall and play a sound when a player walks into a trigger box?
This is additional, different question. If you want to connect it (two question), post your scenario what happens, when should play music and when should start/stop physic. This is simple and for sure somebody will help you.
