This problem was eliminated when using newer versions of the plugin, and the basis was the Mantis helmet. Now I have the n7 armor almost ready, it’s a pity that my skills are very poor.
I set up the model in blender, the textures are approximately normal. After converting to a mesh for the game, the texture is glitchy. Can anyone suggest anything? https://drive.google.com/file/d/1a6H5X55yJ-UcTv8sdytVFxmSCtp3vbg8/view?usp=sharing
