Textures VS materials

I have a mesh (.x file) that have a "base" materials, and only some faces textured, for wich i've built a 256x256 bmp with the "base" material color as a "background" and the details in other color.
This leads me in 2 problems:
1) the non textures part of the mesh seems really different from the textured one: the "raw" material looks like plastic (some shiny faces, etc) while the textured part seems much more opaque, less "reflective".... basically it seems like a carpet on a "gloss" surface.
As now, the only solution i've found is to make a little texture with only the "base" color that i apply at the part that shold not need that, just to keep the thing "similar". How can i better "couple" a material with a texture?

2) The texture colors differs (are "blended") when i change the base material color: i was expecting that the texture will "cover" the faces regardless for the material color. There's a way to make the texture full opaque, and not "semi-transparent" as it appears now?

Thanks

Mesh Subsets

i had this problem too, the way to overcome it is to draw the mesh subsets seperatley, obviously you have to get the number of subsets before you can use this this is easily done when you load the mesh, the maxlimbs

The best thing about drawing the subsets seperately is that you can apply different transforms, materials, textures, lighting, basically treating them as seperate meshes.

The code is simplfied but basically works.

Code:

    Dim Materials as D3DXBuffer, Adjaceny as D3DXBuffer, MaxLimbs as Long

    Set Mesh = Dx8D3D.LoadMeshFromX(File, D3DXMESH_MANAGED, Dx8Device3D, Adjacency, Materials, MaxLimbs)

    With Mesh
            Dim C As Long
            For C = 1 To MaxLimbs
                 'Add draw code here
                 
                .DrawSubset C
            Next C
    End With
