DX8 trouble with mesh animation. PLEASE!!

KingSnake · 2002-01-25T11:54:38

I can''t animate the mesh!! Ok. I''ve made a simple animation in 3d studio max 3, i''ve exported it to a mesh (.3ds), i''ve converted it into a .x file with frames and animations (verified it in text mode of .x file), i''ve opened the .x file as a d3d mesh with this code: //----------------------------------------------------------------------------- // Name: InitGeometry() // Desc: Create the textures and vertex buffers //----------------------------------------------------------------------------- HRESULT InitGeometry() { LPD3DXBUFFER pD3DXMtrlBuffer; //new // Load the mesh from the specified file if( FAILED( D3DXLoadMeshFromX( "alucard2.x", D3DXMESH_MANAGED,//DYNAMIC, //SYSTEMMEM, g_pd3dDevice, NULL, &pD3DXMtrlBuffer, &g_dwNumMaterials, &g_pMesh ) ) ) { return E_FAIL; } D3DXComputeNormals(g_pMesh); //calcola in automatico le normali!! // We need to extract the material properties and texture names from the // pD3DXMtrlBuffer D3DXMATERIAL* d3dxMaterials = (D3DXMATERIAL*)pD3DXMtrlBuffer->GetBufferPointer(); g_pMeshMaterials = new D3DMATERIAL8[g_dwNumMaterials]; g_pMeshTextures = new LPDIRECT3DTEXTURE8[g_dwNumMaterials]; for( DWORD i=0; i = d3dxMaterials[i].MatD3D; // Set the ambient color for the material (D3DX does not do this) g_pMeshMaterials[i].Ambient = g_pMeshMaterials[i].Diffuse= g_pMeshMaterials[i].Specular; // Create the texture if( FAILED( D3DXCreateTextureFromFile( g_pd3dDevice, d3dxMaterials[i].pTextureFilename, &g_pMeshTextures[i] ) ) ) { g_pMeshTextures[i] = NULL; } } // Done with the material buffer pD3DXMtrlBuffer->Release(); return S_OK; } i render it with this: for( j=0; jSetMaterial( &g_pMeshMaterials[j] ); g_pd3dDevice->SetTexture( 0, g_pMeshTextures[j] ); //g_pd3dDevice->SetTexture( 1, g_pTexture); // Draw the mesh subset g_pMesh->DrawSubset( j ); } BUT NO ANIMATION AT ALL! just the first key frame... how do i call the other frames? thanks!

Just a quick thanks to Jim Adams for working on the MS3D skinned mesh exporter... it''s nice to not have to wait until I can afford MAX 4.x and Character Studio to work on skinned mesh code...!

..now it''s just a Small Matter Of Programming to get it working.. lol.. maybe in a few weeks!

Hey Jim,
I tried your milkshape exporter, just using the skinned mesh example that came with DX8.

In text mode, it tells me (always) that it cannot be loaded.

However, I am able to use convx to turn it into a binary file... but when I load that, there are no animations!

Just wanted to see if you might know about this issue. Also, some of the normals on the cylinder I exported are fudged, but you said in your little description that you knew that might be the case.

If you want me to send you the exported models, both x-text and x-binary, I''m willing, just drop me a line at john@raptisoft.com

To everybody that downloaded the exporter - there was a few bugs, and they are all getting resolved. Namely some stuff about the mesh and frames outputed. I still can''t get the normals correct - even when computing my own, the skinned mesh object distorts the final mesh when rendering.

I''ll upload the newest exporter sometime tomorrow.

The newest exporter is there - it''ll fix a couple problems.
Still nonormals.

Hi Jim,

I was wondering if you could give me some pointers on
the UpdateAnimatedMesh function?

Thanks,
Nick
