[Resolved] x-file looks strange

[Mr Mint]

Hi ,

I want to create a function to load x-files. But my tests brought up strange-looking meshes with stranger behavior

I used the tiger from the dx-sdk as x-file

This is the function in Detail:

Loading the mesh

    '// load mesh
    '///////////////////////////////
    
    Set m_meshobj = g_d3dx.LoadMeshFromX(App.Path + "\tiger.x", D3DXMESH_MANAGED, _
                                   g_dev, m_AdjBuffer, MtrlBuffer, g_NumMaterials)

Set the FVF

       Set temp_meshobj = m_meshobj.CloneMeshFVF(D3DXMESH_MANAGED, D3DFVF_VERTEX, g_dev)

Load a texture from ressource

      tex = LoadResData(101, "CUSTOM")
      byte_length = UBound(tex)
      Set current_texture = LoadTextureFromFileFromMemory(tex, D3DFMT_UNKNOWN)
      Set g_Texture_checker = current_texture

Set Material and Texture for each subset
(I use just a default texture for all subsets till the mesh is properly displayed)

get_material and texture fills current_texture (_material) with the ones assigned to the number. set_material (_texture) puts them into an array, checking if they already exist.

    '// 4 each material
    '///////////////////////////////
    For i = 0 To (g_NumMaterials - 1)
        g_d3dx.BufferGetMaterial MtrlBuffer, i, current_material
        
       '// set material
       '///////////////////////////////
        get_material (1)
        set_material (1)
     
       '// set texture
       '///////////////////////////////
        texture_number = 1
        get_texture (texture_number)
        set_texture (texture_number)
    Next i

At first I saw nothing but after doing some scaling the model appeared

So here for the scaling

    Set vb = temp_meshobj.GetVertexBuffer()                           '//VertexBuffer

    size = g_d3dx.GetFVFVertexSize(temp_meshobj.GetFVF())

    count_2 = temp_meshobj.GetNumVertices()
    ReDim verts(count_2)

    D3DVertexBuffer8GetData vb, 0, size * count_2, 0, verts(0)


    For i = 0 To UBound(verts)
        verts(i).x = verts(i).x / 1.09
        verts(i).y = verts(i).y / 1.09
        verts(i).z = verts(i).z / 1.09
    Next i
'    rot_um_x 2 '// rotating 4 testing


    D3DVertexBuffer8SetData vb, 0, size * count_2, 0, verts(0)

After that I do the optimize, this function works properly with my boxes created by the create_box-call

The quadframe.AddD3DXMesh is a function from a M$-Common-files class, some might remember it. This function is also working properly by my create_box-meshes.

    Optimize (texture_number)
    Set m_meshobj = temp_meshobj

    temp_meshobj.GetAttributeTable ByVal 0, AttributeNumber
    quadframe.AddD3DXMesh(m_meshobj, AttributeNumber).SetMaterial_and_texture AttributeNumber
    
    Set m_meshobj = Nothing
    Set temp_meshobj = Nothing

Here are 2 pics of the rendered tiger.x

The first pic shows the loaded model, the second the tiger rotated with 2°


The model is loaded, right vertex-format, material and texture set, so why t.. h... is this mesh not shown properly? The only clue I have is that the buffer has false values, but it looks properly set up.

Thank you for viewing, hope someone can solve this mystery.
