They do not come with an integrated generator, so they produce less sound. Laser Turret, Shotgun Turret, Spotlight, Heavy Laser Turret, and Missile Turret require two power units each. This leads to horribly loud sounds if you place many of them in your settlements. You're most likely either missing a glowmap, or have something wrong with the mesh. Machinegun and Heavy Machinegun turrets come with integrated generators. Check if this matches what is listed for the non glowing part of the weapon (click another part of the mesh and do the same thing for that)
It will highlight the corresponding node in the left panel. Click where on the weapon you want to look, in this case the glowing part.Navigate to mesh of choice, in this case I think it should be meshes/weapons/2handrifle/laserrifle.nif, open with Nifskope (.nif should already be associated with Nifskope).Go to your EVE mod in the left pane of MO, Right Click, and Click Open in Explorer.Launch Nifskope through MO (this allows Nifskope to automatically pull all the correct textures that you've installed through MO).
Here's a general workflow to checking your meshes.
