@dotlogix, would you have any ideas why is that?

Any help on how can I verify what's is wrong here. I really want to work with Stride as a code-only solution for a simple game.

@VaclavElias sorry for the late response I was pretty busy in the last month and couldn't take a look.
Unfortunately, I am not able to reproduce this issue on my machine, both the Debug and Release versions work fine.

Could it be an issue with the backend? Not sure what graphics pipeline Nvidia uses by default as I am using an AMD 6700XT

@thenuts could you try as an experiment to change the IndexType from IndexingType.Int16 to IndexingType.Int32 ?
Maybe Nvidia does not like 16bit ints as indices, although it might be sth else if the geometry shows up correctly for you.

Maybe play around a bit with the data types for vertex colors.

Or another idea would be to try to explicitly set the color vertex stream in the material like so:

new MaterialInstance {
  Material = Material.New(graphicsDevice, new MaterialDescriptor {
      Attributes = new MaterialAttributes {
          DiffuseModel = new MaterialDiffuseLambertModelFeature(),
          Diffuse = new MaterialDiffuseMapFeature {
              DiffuseMap = new ComputeVertexStreamColor
              {
                  Stream = new ColorVertexStreamDefinition(0)
              }
          },
      }
  })
}

If nothing of this helps I am pretty much out of ideas as it seems to be a Stride issue then I guess.

I'm seeing the same problem. A few things to note:

  1. Built with .NET SDK 8.0.100
  2. Switching to IndexingType.Int32 did not help.
  3. The shapes are only visible from one side. Moving the camera to see their backsides makes them disappear, but their shadows are still present.
  4. Running it produced these warnings:

The shapes are only visible from one side. Moving the camera to see their backsides makes them disappear, but their shadows are still present.

That is probably normal behaviour. It does behave, even when you create your Mesh in Stride independently from this example. It behaves like that also on my example below..

Running it produced these warnings:

Are these showed only on the first run?

I am now experimenting with the library as you can see here and the Meshes are working..

The EXEC warning is shown each time. The others are only shown on the first run.

This is how Example01 looks to me. Notice the black 2D squares.

Oh also, running Example01 produced these warnings.

I see. We can ignore the warnings, as most likely they are not causing an issue. Also, the Mesh is most likely ok, as you have the problem generally. Not sure if there is not some issue with lighting, because you have some lights ok but the lights from the dark side are not working..

@Doprez, could it be the Light Probe issue?

This is now facing up, where the light is could you try that?

I changed some of these..

void GiveMeAPlane(MeshBuilder meshBuilder)
{
    meshBuilder.WithIndexType(IndexingType.Int16);
    meshBuilder.WithPrimitiveType(PrimitiveType.TriangleList);

    var position = meshBuilder.WithPosition<Vector3>();
    var color = meshBuilder.WithColor<Color>();

    meshBuilder.AddVertex();
    meshBuilder.SetElement(position, new Vector3(0, 1, 0));
    meshBuilder.SetElement(color, Color.Red);

    meshBuilder.AddVertex();
    meshBuilder.SetElement(position, new Vector3(1, 1, 0));
    meshBuilder.SetElement(color, Color.Green);

    meshBuilder.AddVertex();
    meshBuilder.SetElement(position, new Vector3(1, 1, 1));
    meshBuilder.SetElement(color, Color.Blue);

    meshBuilder.AddVertex();
    meshBuilder.SetElement(position, new Vector3(0, 1, 1));
    meshBuilder.SetElement(color, Color.Yellow);

    meshBuilder.AddIndex(0);
    meshBuilder.AddIndex(1);
    meshBuilder.AddIndex(2);

    meshBuilder.AddIndex(0);
    meshBuilder.AddIndex(2);
    meshBuilder.AddIndex(3);

No change, except for the direction that the plane is pointing.

Thanks for a screenshot. Hmm, I would need some more experienced dev to step in. Are you exploring only code-only or you are also using Stride Game studio. I wonder if you would have the same issue also there, or is it related only to code-only issue.

@RichardMelito
Copy link

This seems to be happening both with code-only and with game studio. I copy-pasted some of the procedural geometry code into my game studio project and noticed that the plane it made was totally black. I then ran the original code-only example from GitHub and saw that everything was still black.

@VaclavElias

What about if you just drop a box to Game Studio, or run some existing Game Studio tutorials (https://doc.stride3d.net/latest/en/tutorials/csharpintermediate/index.html)? Are you having the same issue there? If yes, could you screenshot for us?

@RichardMelito
Copy link

I have only seen the issue when using the community toolkit code.

Here is a screenshot from the PhysicsSample. You can see the cubes that come with it, plus 2 capsules that I dragged and dropped. One has no material, and the other has the built-in Materials/CubeMat material.

And do you use toolkit's NuGet or directly toolkit source code?

@RichardMelito
Copy link

Both:

I copy-pasted some of the procedural geometry code into my game studio project and noticed that the plane it made was totally black.

The toolkit was definitely referenced as a NuGet package when I tried integrating it into my existing project.

I then ran the original code-only example from GitHub and saw that everything was still black.

The GitHub examples reference the Stride.CommunityToolkit project directly, but that in turn references the engine's NuGet packages. Not sure if that's relevant but just wanted to point it out.

We are referencing the same packages. I was wondering if some updates were made..

For what it's worth, I cannot reproduce the problem on my laptop. Its specs are:
OS: Windows 11 Home version 10.0.22631 Build 22631

GPU: Intel Iris Plus Graphics
Graphics driver: Driver version 31.0.101.2125

That is really a mystery!!🤦‍♂️Let's see if we can get some input from others.

@RichardMelito

Could it be a problem with NVIDIA GPUs?

@VaclavElias
Copy link
Collaborator

It would be good to find out, if the issue is only happening when you are using the toolkit. The reason for that is that toolkit is in preview and I am trying to figure out the correct settings for the GraphicCompositor which might be affected by GPU.

This example #65 (comment), if you do it through Stride Studio, without any reference to the toolkit, does it also lose colours.

These are my steps I did through Stride Studio. If you can get the same result, it means the issue is in the toolkit. If not, then I don't know.

  1. Create new project - New game template
image
  1. Default settings left as it is
image
  1. I added a cube without material
image
  1. And this is the result, all good

@RichardMelito

That works, so it seems like it's something in the community toolkit.

It works for me also, but I think this is different; how can we create a ComputeVertexStreamColor from the editor?
