Hi Phillips, I am very sorry to hear that. Could you please explain me more in detail what problem you have? I have updated the .zip file, could you check if the good texture is atached?
Edited: Found out my problem, unreal engine was compressing the texture. Models look great now, thanks for the update!
For anyone importing to unreal, make sure that your texture group is set to 2D pixels, Compression settings to UserInterface2D, and sRGB turned on. And material set to two-sided.
