Question about Control+Click combining

Does control+right clicking several objects to group them into one logical unit reduce how the engine sees them? I’m looking to reduce resource consumption by combining meshes (like an entire group of houses or segments of wall, things that won’t change).

I did try to ferret out this answer online but I think I may be asking the wrong question or perhaps using the wrong terms.

Thanks in advance

Grouping is only for editor, to easily manipulate groups of objects.

To combine meshes .you should try to use merging

Thank you, that did the trick. I had a feeling I was searching with the wrong terms.

The never ending struggle to maintain reasonable client FPS.

Thanks again!
