How to fix this shadow issue

Question

I try using Ellen BH as my base model for Miyabi. But when export and put ingame she got this shadow issue that I don't know what cause it. I did check all the normal map (flat), light map and material map every thing is the same as her leg section. If there is solotion or if somone know what cause the issue pls let me know. Thanks. The skin is working fine when stay in lighting only in shadow that got is darker issueUpdate:- Shadow area where light not hit got multiply. Don't know what cause it.already check : LightMap, MaterialMap, in Blend file: TEXCOOR (put same color match body and leg), COLOR attribute (for some reason it only affect lighting area when edit alpha from 0 to 1)I upload new screenshot. with Disable NormalMap and LightMap for both Body and Legs. it look like the body turn green and not match the leg.

It ended up being really weird. I'm not sure why this is necessary or works, but basically to fix it you have to load the upper body as part of the legs model by loading its ib in the same section where you load the legs ib. Also have to load the body vb0-3 and use a resource variable for vb0 and vb3, which is set using the body vb0. Finally you also need to make sure that TextureOverrideMiyabiBodyA does not include drawindexed at all and is just skipped.Example code:[TextureOverrideMiyabiBodyBlend]
hash = 9a4227c8
handling = skip
vb2 = ResourceMiyabiBodyBlend
if DRAW_TYPE == 1
	vb0 = ResourceMiyabiBodyPosition
	draw = 8064,0
endif

[TextureOverrideMiyabiBodyTexcoord]
hash = 303fb1b6
vb1 = ResourceMiyabiBodyTexcoord

[TextureOverrideMiyabiBodyVertexLimitRaise]
hash = 6201dd9e
override_vertex_count = 8064
override_byte_stride = 96

[TextureOverrideMiyabiLegsBlend]
hash = bc586fd9
handling = skip
vb2 = ResourceMiyabiLegsBlend
if DRAW_TYPE == 1
	vb0 = ResourceMiyabiLegsPosition
	draw = 31168,0
endif

[TextureOverrideMiyabiLegsTexcoord]
hash = fb94d66c
vb1 = ResourceMiyabiLegsTexcoord

[TextureOverrideMiyabiLegsVertexLimitRaise]
hash = 8336ded4
override_vertex_count = 31168
override_byte_stride = 92

[TextureOverrideMiyabiBodyIB]
hash = 981c1a1e
handling = skip

[TextureOverrideMiyabiBodyA]
hash = 981c1a1e
match_first_index = 0
ResourceBodyAVB = copy vb0

[TextureOverrideMiyabiLegsIB]
hash = d8003df3
handling = skip

[ResourceBodyAVB]

[TextureOverrideMiyabiLegsA]
hash = d8003df3
match_first_index = 0
run = CommandListSkinTexture
ib = ResourceMiyabiLegsAIB
ps-t4 = ResourceMiyabiHairANormalMap
drawindexed = auto

ib = ResourceMiyabiBodyAIB
vb0 = ResourceBodyAVB
vb1 = ResourceMiyabiBodyTexcoord
vb2 = ResourceMiyabiBodyBlend
vb3 = ResourceBodyAVB
drawindexed = auto

[TextureOverrideMiyabiHairADiffuse]
hash = 012e84e9
this = ResourceMiyabiHairADiffuse

[TextureOverrideMiyabiHairALightMap]
hash = a6ea6d83
this = ResourceMiyabiHairALightMap

[TextureOverrideMiyabiHairAMaterialMap]
hash = d5462e37
this = ResourceMiyabiHairAMaterialMapI had never seen this type of thing before so pretty surprised. Studied Exce's mod and FleurNaive's mod to figure this out. Always happy to learn something new though.2 things to check:The red channel of light maps is unique to each texture/model. It basically assigns material properties based on the value, but not all parts of a body have the same ones available. In other words a particular shade of red on the body light map will not behave the same on the legs light map. So you have to adjust the red channel through a lot of trial and error until you get it to look right. Or you can look at the red channel from other similar mods for Miyabi and just copy what red value they use.Vertex Color. Check Vertex Paint mode in Blender and make sure that the seam where the lower and upper body meet has the same vertex color. For the best results when checking this change to Solid shading with flat lighting and no specular lighting.

it looks to me like a separate layer is casting a shadow while appearing invisible, are there any other lightmaps in your files?
