Hi there, in the mesh loading function from most tut's there this bit of code // Bones for skining if(m_frameRoot) { //MessageBox(NULL,"We HAve Frames", "Test", MB_OK); TCHAR msg[MAX_PATH]; sprintf_s(msg,MAX_PATH, "We have frames number bones = %d",m_maxBones); MessageBox(NULL,msg,"Error Code Area 1", MB_OK); // Set the bones up SetupBoneMatrices(device,(D3DXFRAME_EXTENDED*)m_frameRoot, NULL); // Create the bone matrices array for use during FrameMove to hold the final transform m_boneMatrices = new D3DXMATRIX[m_maxBones]; ZeroMemory(m_boneMatrices, sizeof(D3DXMATRIX)*m_maxBones); // Calculate the Bounding Sphere for this model (used later to position camera correctly) D3DXFrameCalculateBoundingSphere(m_frameRoot, &m_sphereCentre, &m_sphereRadius); } Question: Now if m_maxBones = 0 is this going to be a problem. Because in the one Im using it crashes on this mesh object with no bones or animation
