The Nihil turret's cold core is now visible

The Nihil turret in Shattered Rift now shows its cold core through an open-waist housing. Narrow-root barbs replace the opaque shapes that used to hide it. The screenshots are close renders. The first shows the revised turret, the second shows the original, and the third shows the revision from a higher angle. Hit radius, health, materials and flying roles are unchanged. Some thorns still block the view at oblique angles. This is a limited readability improvement, not a final art pass, and the images are not flight footage.
