Since the re-scale of the Dire Wolf, the (I) variant has an untextured portion on its torso. It is a ring around the protruding part that contains the head.
All of the other Dire Wolf Variants are normal as far as I know. Since the (I) variant cannot change patterns, I changed to multiple colors and the look is the same.
Technically this should be in the previous patch feedback, but I did not notice this until recently.
Description:
The Dire Wolf, DWF-Prime(I) has an untextured portion on its torso which surrounds the protruding part of the torso that contains the head (Like a "ring"). It is seen as the white part in this picture.

The graphics setting I am on is "High".
All other Dire Wolf variants do not have this untextured portion. They look like this:

Location: Around the head, in the round part of the torso that contains the head
Reproduction Rate: 100%
Steps to Reproduce: Select your mech as a DWF-Prime(I) Variant.
