I’m trying to get all of the textures out of my FBX file. I’ve been looking at the examples and forum posts but I still have yet to really understand what I need to do. So far I think this is on the right track:

KFbxProperty lProperty;
int lNbMat = FBXMesh->GetNode()->GetSrcObjectCount(KFbxSurfaceMaterial::ClassId);
for (int lMaterialIndex = 0; lMaterialIndex < lNbMat; lMaterialIndex++)
{
 KFbxSurfaceMaterial *lMaterial = (KFbxSurfaceMaterial *)FBXMesh->GetNode()->GetSrcObject(KFbxSurfaceMaterial::ClassId, lMaterialIndex);

 if(lMaterial)
 {
  int lTextureIndex;
  FOR_EACH_TEXTURE(lTextureIndex)
  {
   lProperty = lMaterial->FindProperty(KFbxLayerElement::TEXTURE_CHANNEL_NAMES[lTextureIndex]);
   KFbxTexture* lTexture = KFbxCast <KFbxTexture> (lProperty.GetSrcObject(KFbxTexture::ClassId, 0));
  }
 }
}

What do I do after this to get the RGBA channels in a standard byte array so I can create a OpenGL texture from it?

Also the textures are embedded into my fbx file.

You get the file name, then read in the file yourself.  Embedded textures are extracted into files during the import process.  I don’t think you can read them directly from the FBX file for embedded textures.

The textures actually are in the FBX file which means there must be a way to get them out. I know the quicktime viewer can extract the textures so there must be a way to do it with the FBX SDK.

There may be a way, but I don’t think the quicktime viewer uses the FBX SDK. 

Using the SDK, the textures are extracted to files during the Import process and that is your only option, I believe.
