Ah i see .........that is one the 3D model makers (Mindflux's readme) for a particular model / accessory used in the pack ...
It has to be there for legal reasons .... you will find another list with other model info too and some will say low poly.
I would like to try to help understand the issue you are having ...... so a screenie of an example of how things look on your system may help .
It may be a graphics issue related specific to your set up ..... also some info about your system would also help .
I personally have a really old PC (7 years old now ) and an old 1080Ti of which the game screenie in the First Post was taken from .
