Parched mob texture overlap — second layers of legs and torso share UV space; unused area in texture

Description

The new “Parched” mob has a texture mapping issue.
Parts of its model overlap on the UV map, and part of the texture is not used by any model element.

Specifically:

• The second layers of both legs and the torso overlap each other in the texture.

• There is also an unused region in the texture that corresponds to no model face.

This causes visual artifacts and makes the texture inconsistent, complicating retexturing or editing efforts.

Expected Result

Each model layer should have a unique, non-overlapping area on the texture, and all texture regions should correspond to a part of the model.
There is enough available space in the current texture layout to properly separate all UV islands without overlaps.

Observed Result

UVs overlap (especially the second layers of legs and torso), and part of the texture remains unused.
The attached images show both the visual artifact in-game and the highlighted overlaps/unmapped regions in the texture.
Attachments

• Visual artifact (in-game) — shows the rendering issue caused by overlapping UVs. (red)

• Unused texture areas highlighted — shows regions of parched.png not mapped to any model face. (red)

• Overlapping UVs highlighted — shows the second layers of the legs and torso sharing the same texture space. (red)
