Pixel Sprite

[Shioban]

Its not a shadow of anything. Its on the wall in two different spots.

That's how baking works, for example the image below shows the lighting (lightbounces), shading, shadows, ambient occlusion shading and any light bleeding/influences on surface materials;



Essentially what it does is it bakes the lighting onto the 3D object then applys it as a texture (on top of whatever is marked as static). To lower the rendering cost you can mix baked lighting with real-time lighting to achieve a nice effect (however FFXIV might not have done this)

But it looks like a low quality light bake that's been left applied to that texture.
