Normal maps and specular maps aren't correct out of the box

[OTCompa]

The raw texture images are extracted and don't go through any processing other than hue changes. This is an issue as XIV does not store them in the format expected by other 3D tools (I think)

Left is the raw extracted texture, right is the extracted texture from exporting the respective model as .FBX in Textools

Should be fixed but I don't really know how to look for issues other than very basic issues.
Normals: 01651d4
Speculars (I looked at Meddle for this): ec5a8bc, OTCompa/ZoneFbxBlenderPlugin@683502c
Unfortunately, from my research it seems like handling the specular properly in .FBX isn't possible without some intervention.
Some textures were also not being exported as any material with 2 samplers that use the same texture were counted as separate textures, this is fixed here ec5a8bc

Specular in this model is only white, causing it to be "darker" due to maxed out roughness and metallic (with the blender plugin), it should be brighter as it converges towards the center based on this image from #13

Not 100% sure if it's just lighting but worth looking into still
