📋 About This Mod
What is this and what does it do?
Another version of my Rex Dogmeat replacer but this time designed to be much more accurate to Rex's appearance.
Notes and compatibility:
--Because of Rex's size and shape dog armor mods may have some clipping issues on both his face and body.
--Because of Rex's ears being part of his brain case (as they were in NV) I've had to severely reduce the amount that the ears move to avoid weird stretching with the glass dome of the brain case. They still do flick and move slightly though.
--I've also included an optional file that has the new body and textures but the 'old' style head from my other Cyberdog Rex mod for people who prefer the more streamlined look and more emotive ears.
