when converting a map from kn5 to obj and opening it in blender 99% of textures are completely blue.

I convert .kn5 files to .fbx files and try to open with three.js and other 3D viewers available online, but I get the same error. The model files are here.

When exporting kn5's to OBJ there's an issue with the UV scaling, the scaling is too larger, which causes the texture to look small and tilled as seen in the picture.
From lines 674 to 678 you have an IF statement that uses the parameter DetailUVMultiplier from the material and applies it to the actual mesh. which I think is wrong. since shader-related scaling should not be applied to the actual mesh but stay in the shader/material or passed to the mtl and then processed. Removing that line fixes the UV scaling issue.
