Diagnosing lag with builds

I recently made this post asking how to solve a lag issue in my game:

This is the gif included in the post. I cant conclude “too many parts” or something basic because typically that only causes FPS drops and not incremental freezes like showcased in the gif.

If you don’t read the post a tl;dr is that a castle was causing these spikes and when away from the castle the lag wouldnt appear. I was wondering how I could diagnose the source of the problem? Potentially utilizing the F9 console what should I look for?

Does unioning together a bunch of parts reduce lag, increase it, or does it not matter or its not significant enough to even fix my problem. I use streaming enabled btw.

All help is greatly appreciated I’ve been struggling with this all day long and its been super annoying.

ctrl+shift+f5. check for physics and render, if the physics goes red on the bearing you are looking at mostly means there is un-anchored parts which is causing the area to have physica issues. For render, basically means there is too much parts, or either your PC is not very good. Theese are all past experiences for me, it might not be accurate or what you are looking for.

My theory is that there’s simply too many loose parts in the workspace.

I’d suggest exporting them to a 3rd party modelling software, cleaning them up, and then importing them as one part, to increase performance and reduce part count.

I am curious what benefit does converting it to a mesh offer?
I’ve been told that just turning a union into a mesh wont help at all and you have to actually take it into blender and reduce the geometry. But I’ve also been that just converting it is fine.

Converting only reduces part count, which helps slightly, however not by a huge margin.

Exporting it, cleaning it up, and re-importing it is way better than just converting it.

I imagine it’d be very useful when I have the following:

A wooden chair that consists of 49 parts
A single bed that consists of 128 parts
Bunk bed that consists of 289 parts
Dresser that consists of 107 parts
Smaller dresser that consists of 65 parts

Is it worth reducing geometry in my case? Or considering how I use a lot of parts to get lots of detail in my models is it significant enough to be fine just converting them to meshes?

Removing any unnecessary triangles (tris) is helpful at reducing performance impact, really.

Got it, I’ll reduce geometry through blender thank you for the help. Greatly appreciated.
