Hi , i use that very nice Library since 1 year now. Normally i can find everything i want with the official documentation web site. But recently, i am front a new problem.

How to use correctly the class [MeshInstancingNode].
I try to follow the DigitalRune sample =>
Graphics - DeferredRendering - Number 31- BatchingSample
I meet not exception but Nothing is draw on the screen. If i don't try to use instancing and choose not use the class [MeshInstancingNode] , eerything draw correct.

Here is the code i use :

`
int numberOfInstances = listVectorScaleOctree.Count;
InstanceData[] InstanceData = new InstanceData[numberOfInstances];

for (int i = 0; i < numberOfInstances; i++)
{
InstanceData[i] = new InstanceData(listVectorScaleOctree[i], listPoseOctree[i], new Vector4F(1));
}

blockGroup.MeshInstanceData = new MeshInstancingNode(tempMeshNode.Mesh, InstanceData)
{
// It is recommended to manually set a suitable pose and shape, so that
// the bounding shape contains all instances.
PoseLocal = new Pose((Vector3F) GetCenterOfBoundingBox(bdgRef.Value)),
Shape = new ConvexHullOfPoints(listPositionOctree),
ScaleLocal = new Vector3F(
Math.Abs(bdgRef.Value.Max.X - bdgRef.Value.Min.X),
Math.Abs(bdgRef.Value.Max.Y - bdgRef.Value.Min.Y),
Math.Abs(bdgRef.Value.Max.Z - bdgRef.Value.Min.Z)
)
};

blockGroup.MeshInstanceData.Name = "cube";
blockGroup.MeshInstanceData.IsStatic = true;
blockGroup.MeshInstanceData.CastsShadows = false;
blockGroup.MeshInstanceData.IsShadowCasterCulled = false;
_Scene.Children.Add(blockGroup.MeshInstanceData);
`
Many thanks in advance guys

Hi guys, i have a problem when i try to load a fbx model with DigitalRune. It's little bit weird cause before with the trial version, everything goes well.
Here is the message i get on the Monogame pipeline tools :
'System.Object DigitalRune.Animation.Character.Skeleton.get_Internals()'

If somebody know how to solve this problem, i will be very gratefulto him ^^
Many thanks in advance, i keep hope

Hi, i hope still have some people available to help me on DigitalRune . I use that library for make a small voxel game.
Everything goes well. except when i try to render a fog. I don't know what i am doing wrong. I follow exactly the documentation here : http://digitalrune.github.io/DigitalRune-Documentation/html/0bc6a222-64d5-4642-a2b6-241e9017c873.htm
I used the fog object class in the digitalRune sample.

Here is my render function i use :

protected override void OnRender(RenderContext context)
        {
            _frameCount++;
            if (_stopwatch.Elapsed.TotalSeconds >= 1)
            {
                Globals.FramePerSecond = _frameCount / (float)_stopwatch.Elapsed.TotalSeconds;
                _stopwatch.Restart();
                _frameCount = 0;
            }
            if (context.GBuffer0 == null)
            {
                var renderTargetPool = GraphicsService.RenderTargetPool;
                var width = context.Viewport.Width;
                var height = context.Viewport.Height;
                context.GBuffer0 = renderTargetPool.Obtain2D(new RenderTargetFormat(
                  width,
                  height,
                  false,        // Note: Only the SaoFilter for SSAO requires mipmaps to boost performance.
                  SurfaceFormat.Single,
                  DepthFormat.Depth24Stencil8));
            }

            var graphicsDevice = GraphicsService.GraphicsDevice;

            context.CameraNode = CameraNode;
            context.LodCameraNode = CameraNode;
            context.Scene = Scene;

            graphicsDevice.Clear(Color.Black);

            // Frustum Culling: Get all the scene nodes that intersect camera frustum.  
            CustomSceneQuery sceneQuery = Scene.Query<CustomSceneQuery>(context.CameraNode, context);


            // Render opaque meshes.                                                     
            graphicsDevice.DepthStencilState = DepthStencilState.Default;
            graphicsDevice.RasterizerState = RasterizerState.CullCounterClockwise;
            graphicsDevice.BlendState = BlendState.Opaque;
            graphicsDevice.SamplerStates[0] = SamplerState.LinearWrap;
            context.RenderPass = "Default";
            _meshRenderer.Render(sceneQuery.RenderableNodes, context);


            // ----- Sky
            _skyRenderer.Render(sceneQuery.SkyNodes, context);
            // ----- Fog
            sceneQuery.FogNodes.First().IsRenderable = true;
            _fogRenderer.Render(sceneQuery.FogNodes, context);

            DebugRenderer.Render(context);
            //_sceneNodes.Clear();
            context.RenderPass = null;
            context.CameraNode = null;
            context.Scene = null;
            //context.GBuffer0 = null;
        }

Hi,
I have managed to compile the projects to create the dlls to replace the older ones in my interop-UWP application. But now I need to create the following 4 dlls for the Pipeline:

DigitalRune.Animation.Content.Pipeline.dll
DigitalRune.Geometry.Content.Pipeline.dll
DigitalRune.Graphics.Content.Pipeline.dll
DigitalRune.Mathematics.Content.Pipeline.dll

But I can't manage to do that because I get some errors. Has anyone created this files succesfully? it could be possible for anyone to upload them?
Thanks in advance.

DigitalRune Engine 2016-03-10 (For existing customer only!)
Could I have a license key that I can use?
I wanted to simplify the process to test some of my applications.
Thanks a lot.

Hi ,
Yes i'm still using your pretty XNA library ^^
I just have a problem with the [Under Water Effect] .
When i go under the water, the effect work very well. But the problem , is about the edges of the water node shapes !
My game is a "voxel game", so for example , a river is made with many water nodes voxel. And when i move the camera under the water, i can see the edge from all the nodes, each time i cross a new waterNode with the camera.
Do some people have a solution with that ?
I really hope soo. I'm so close to finish a "Beta" version of my game. Thanks a lot

Here is the code i use for create the shape and add the waterNode:

var waterOcean = new Water
{
	SpecularColor = new Vector3F(20f),
	SpecularPower = 500,

	NormalMap0 = null,
	NormalMap1 = null,

	RefractionDistortion = 0.1f,
	ReflectionColor = new Vector3F(0.2f),
	RefractionColor = new Vector3F(0.6f),

	// Water is scattered in high waves and this makes the wave crests brighter.
	// ScatterColor defines the intensity of this effect.
	ScatterColor = new Vector3F(0.05f, 0.1f, 0.1f),


	// Approximate underwater caustics are computed in real-time from the waves.
	CausticsSampleCount = 3,
	CausticsIntensity = 3,
	CausticsPower = 100,
};
WaterWaves waterWaves = new OceanWaves
 {
	 TextureSize = 32,
	 HeightScale = 0.01f,
	 Wind = new Vector3F(40, 0, 10),
	 Directionality = 7,
	 Choppiness = 1,
	 TileSize = 10,
	 CpuSize = 32,
	 // If we enable CPU queries, we can call OceanWaves.GetDisplacement()
	 // (see Update() method below).
	EnableCpuQueries = true,
 };
 
 Mesh mesh = MeshHelper.Merge(tempMeshNode.Mesh, listVectorScaleOctree, listPoseOctree);
var shape_init = new TriangleMeshShape(mesh.ToTriangleMesh());

WaterNode _waterNode0 = new WaterNode(waterOcean, shape_init)
{
	SkyboxReflection = Window_Game.Scene.GetDescendants().OfType<SkyboxNode>().First(),
	DepthBufferWriteEnable = true,
	IsStatic = true,
	EnableUnderwaterEffect = true,
	Flow = _waterFlow0
};

_waterNode0.Waves = waterWaves;
Window_Game.SceneWater.Children.Add(_waterNode0)
```;`

Following the build instructions on the front page is not enough to get DigitalRune build:

what I have done:

git clone https://github.com/DigitalRune/DigitalRune.git
cd DigitalRune/
git submodule update --recursive --force
==> does nothing actually !
=> step 2 impossible to run

MonoGame fork source is not downloaded, so I did:
git clone https://github.com/DigitalRune/MonoGame.git

Source/MonoGame/Protobuild.exe
Build\Module.xml has been created.
==> ???
so:

cd Source/MonoGame/
./Protobuild.exe -generate

=> generate solutions.

this version (custom ? old ?) does not support -build command as opposite to main MG branch :(.
so, with VS 2015 com, open DigitalRune-MonoGame-Windows.sln

build command => 8477 errors, 153 warnings, no project can be built
there are a lot of ref missing for some projects (content.pipeline.windows: assimp, cppnet, freeimage, ...)

EDIT: after restoring nuget packages I got: 483 errors and 109 warnings. Still not good.

Build instructions are wrong/not detailed enough and/or not accurate.
(Not revealing build process used by DR for the commercial version of the engine is a big mistake IMHO).

So bonus questions:
does anyone actually succeed to build the engine from source ?
If yes, do you mind sharing your way of doing it ?

This engine looked promising, until I saw that not only can no one contribute to the source, but none of the original devs are supporting it. Someone tell me some actual contributors are coming in soon.

Hi, I'm coming here cause i meet some problem for loading the models in my project. I don't know wich configuration i need use for build my Fbx models for Universal App.
Here i find the official documentation, but only for build the Fbx models for Windows desktop App.

http://digitalrune.github.io/DigitalRune-Documentation/html/53ee55e3-b4a5-42cc-b47d-88d18b9de2f5.htm

Why about universal app please ?

Hi,
First of all, thanks for the release, I have own game engine written in C#, would like to use some concepts about the Editor and WPF, can I use your own stuff in my commercial game engine?

Sorry for question
