//Problem, but the .X file is rendered correctly

DX9 Need help with .X File
Author
Hi all, I'm facing a serious problem..I have exported a .X file from 3ds Max by using Pandasoft exporter.
Now my problem is..when i draw the .X file in my program then all other objects which is not .X file has corrupted (all the vertices and textures has corrupted)
Anyone know what's my problem is??
Please, I need urgent help :(
//some of the sample codes
D3DXMATRIX matTrans;
D3DXMATRIX matSpaceshipWorld;
D3DXMatrixIdentity(&matTrans);
D3DXMatrixIdentity(&matSpaceshipWorld);
D3DXMatrixScaling(&matTrans, 0.5f, 0.5f, 0.5f);
D3DXMatrixMultiply(&matSpaceshipWorld, &matTrans, &matSpaceshipWorld);
pd3dDevice->SetTransform(D3DTS_WORLD, &matSpaceshipWorld);
spaceship->drawSpaceship(pd3dDevice); //this is to draw .X file
// background matrix
D3DXMATRIX matWorldBg;
D3DXMatrixIdentity( &matWorldBg );
D3DXMATRIX matBgTrans;
D3DXMatrixIdentity( &matBgTrans );
D3DXMatrixScaling(&matBgTrans, 200.0f, 200.0f, 200.0f);
D3DXMatrixMultiply(&matWorldBg, &matWorldBg, &matBgTrans);
D3DXMatrixTranslation(&matBgTrans, -100.0f, -10.0f, -100.0f);
D3DXMatrixMultiply(&matWorldBg, &matWorldBg, &matBgTrans);
//set background matrix
pd3dDevice->SetTransform(D3DTS_WORLD, &matWorldBg);
//set background texture and draw it out
drawBg(); //this is to draw normal objects by using DrawPrimitive() only
//Without rendering .X file, only the background
//Problem, but the .X file is rendered correctly

Post the code for drawSpaceship() and drawBg() (using source tags - the FAQ has instructions).
Also, functions like D3DXMatrixScaling() completely initialize the matrix passed as an argument, so there's no need to initialize it to the identity matrix using D3DXMatrixIdentity().

//function for drawing mesh Spaceshipvoid Spaceship::drawSpaceship(LPDIRECT3DDEVICE9 pd3dDevice){ for (DWORD i = 0; i < numSpaceshipMaterials; i++) { pd3dDevice->SetMaterial (&pd3dSpaceshipMaterial); pd3dDevice->SetTexture (0, pSpaceshipTextureList); pd3dMeshSpaceship->DrawSubset(i); }}void drawBg(){ pd3dDevice->SetTexture(0, pd3dTextureBg); pd3dDevice->DrawPrimitive( D3DPT_TRIANGLESTRIP, 97, 2 );}
In drawBG(), you need to call SetStreamSource and SetFVF. That's because the DrawSubset calls in drawSpaceship have overwritten the values they set.
So basically, the call to DrawPrimitive is using the vertex buffer and vertex format of the mesh.
