Hello I am struggling with fixing this shadier issue, the calculated lighting that is attached does not react accurately. The tangentNormal is just the normal texture and it appears accuractly however the TBN that gets calulcated does not. I am new to shaders so I am unsure what is directly causing issues, any help is welcomed
