hey,
i’ve recently enabled streamingenabled and since then I got this bug
Normally, there’s only 1 red big part (hitbox) and its invisible. StreamingEnabled makes it visible and somehow creates several other red/orange parts??
Like, right after you enabled it? And disabling it doesn’t have the issue?
Seems like a Script cause this?
StreamingEnabled shouldn’t cause this issue, except if your making these Parts invisible on the Client.
Exactly. Disabling fixes it 
There arent any parts in normal studio mode but once I click play they are there. Like I said the one big part is the hitbox which is invisible. But i have no clue where the others come from and why the hitbox is becoming visible.
