Hello. The problematic models are used in this game, as well as the main version of this game. BaA:R - Development Testing - Roblox
I will DM a place with a few models that have this issue. Mirrored in this private DM too https://devforum.roblox.com/t/re-streamingmesh-models-are-regularly-way-higher-poly-than-the-original-model/3304343
I also see that after copy and pasting them into a new place file, I’m seeing the streaming meshes significantly offset from where the actual model physically is. I’ll send you the file with this issue too since this issue has occurred for me randomly for a very long time and I could never pin it down enough to make a bug report.
To get these out of the repro file I sent you, I disabled and re-enabled the StreamingMesh property on one of the given models to fix the offset. You can see that there are slightly fewer drawcalls, but polycount is doubled. It should be possible to reduce drawcalls by removing expensive materials and such, while also using the lower poly combined mesh.
