Unable to load FBX about fna

And if i add the extension .fbx i get the following error:

An unhandled exception of type 'Microsoft.Xna.Framework.Content.ContentLoadException' occurred in FNA.dll

Additional information: Could not load Ship.fbx asset!

Looks like it's not even supporte internally

                if (typeof(T) == typeof(Texture2D) || typeof(T) == typeof(Texture))
                {
                    Texture2D texture = Texture2D.FromStream(
                        graphicsDeviceService.GraphicsDevice,
                        stream
                    );
                    texture.Name = assetName;
                    result = texture;
                }
                else if ((typeof(T) == typeof(SoundEffect)))
                {
                    result = SoundEffect.FromStream(stream);
                }
                else if ((typeof(T) == typeof(Effect)))
                {
                    byte[] data = new byte[stream.Length];
                    stream.Read(data, 0, (int) stream.Length);
                    result = new Effect(graphicsDeviceService.GraphicsDevice, data);
                }
                else if ((typeof(T) == typeof(Song)))
                {
                    // FIXME: Not using the stream! -flibit
                    result = new Song(modifiedAssetName);
                }
                else if ((typeof(T) == typeof(Video)))
                {
                    // FIXME: Not using the stream! -flibit
                    result = new Video(modifiedAssetName, graphicsDeviceService.GraphicsDevice);
                }
                else
                {
                    stream.Close();
                    throw new ContentLoadException("Could not load " + assetName + " asset!");
                }

no mention of Model type :/

We can't read raw FBX files, they need to be compressed by the XNA content pipeline.

Oh that sucks :/

[flibitijibibo]

Yeah. Feel free to write your own reader though, I think the MGCB has a parser for it.

FBX support is no easy problem to solve. Official SDK isn't permissive and assimp doesn't support it very well. There's OpenFBX these days, it's usable but relatively young. Not sure what MGCB uses.

[flibitijibibo]

If someone wants to come up with Model.FromStreamEXT I'd be willing to merge it, but you have a few requirements:

• Must be permissive (so yeah, SDK is out)
• Must support the very old 2006.11 format, per the XNA specification
• Must not add any new DLLs, or must load the new DLL dynamically with Assembly.Load (so if we add assimp that's how we'll integrate it)

MGCB may have something we can use, but our goal needs to be to contribute to existing model loading code and simply push that through the equivalent of XNA's ModelProcessor. In doing this, we may be able to add other formats as well (obj and the like).

[carlos-ferreira]

I read here that MonoGame uses assimp to import FBX files. There's even a 3D model viewer that uses assimp to load 3d models.

Is this something we could use or integrate on FNA ?

At this point in time we have absolutely no interest in supporting an official path for model loading. You are more than welcome to pull a library into your project to handle this.
