    having issues with proc mesh normals, never posted here so gl to me but um I think its an issue with normals not showing, the normal map isn't showing on EAST and WEST faces in first image and when past a certain size in the second image you can see another weird issue, I think these 2 are related issues but not sure. heres code https://hatebin.com/diqlqsgkld

    In order for tangent space normal mapping to work your model also needs tangents as well as normals. I can't see you generating any tangents in your code.

    im not sure because the recalculate tangents I think it fixed the face not showing normal map but the blackness is still there and it seems that the SizeX and sizeZ don't represent values , like it could be 30x60 with sizeX 60 and sizeZ 60
