Go to Editor Settings > Experimental and enable Actor Merging. Restart the editor and now when you select multiple meshes and right click you’ll see Merge option. The rest is self explanatory but feel free to ask away if you have any questions.
There is any way to increase performance in game to combine many small meshes in scene to render all at once (to decrease Draw Calls). I sow there is a Group Actor but this one not affect performance propablly.
