Problem loading textures using XNA renderer

Hi, I'm trying to get a simple scene going for an XNA Windows Game project.
I have the following:

Entity ninja = scene.CreateEntity("bob", "ninja.mesh");
SceneNode ninjaNode = scene.RootSceneNode.CreateChildSceneNode();
ninjaNode.AttachObject(ninja);

But when I run the Game, it renders absolutely nothing. I check the log file and it tells me it can't find nskingr.jpg

Anyway, I set the ninja material to:
ninja.MaterialName = "BaseWhite";

and I can see the ninja, albeit without his texture.

I'm fairly certain this has something to do with the Content Project. Does the XnaResourceGroupManager look for .xnb's or the normal extensions?

I find it odd, because the ResourceGroupManager found the ninja.mesh resource, but can't locate the texture.

If you are using the XnaResourceGroupManager, then yes, it is looking for Textures to have been processed by the Content Pipeline, as internally it uses a call to content.Load<>() to load the Texture. This would put the textures, and shaders into xnb files. It's able to find the Mesh, because it's only specifically looking for Textures and GPUPrograms using the ContentPipeline.

Alright, I know that the .xnb's are present. Perhaps you can shed some light on why it's not finding the textures. I have the following code:

  Code:

protected override void SetupResources()
        {

            (new XnaResourceGroupManager()).Initialize(new string[]
                                                         {
                                                             "png", "jpg", "bmp", "dds", "jpeg", "tiff"
                                                         });
           

            string titleLocation = string.Empty;

#if (XBOX || XBOX360)
            titleLocation = StorageContainer.TitleLocation + "\\";
#endif
            ResourceGroupManager.Instance.AddResourceLocation(titleLocation + "Content\\Compositors", "Folder");
            ResourceGroupManager.Instance.AddResourceLocation(titleLocation + "Content\\Fonts", "Folder");
            ResourceGroupManager.Instance.AddResourceLocation(titleLocation + "Content\\GpuPrograms", "Folder");
            ResourceGroupManager.Instance.AddResourceLocation(titleLocation + "Content\\Materials", "Folder");
            ResourceGroupManager.Instance.AddResourceLocation(titleLocation + "Content\\Meshes", "Folder");
            ResourceGroupManager.Instance.AddResourceLocation(titleLocation + "Content\\Particles", "Folder");
            ResourceGroupManager.Instance.AddResourceLocation(titleLocation + "Content\\Skeletons", "Folder");
            ResourceGroupManager.Instance.AddResourceLocation(titleLocation + "Content\\Textures", "Folder");


            base.SetupResources();
        }

images in the texture folder are set to compile, and to never copy to output directory. Use Content Pipeline is set to false.
Ideas?

Try setting Use Content Pipeline to true.

Won't I be needing a valid vertex and pixel shader set for every draw?

Edit:
Ok, I set on Save Generated Shaders, and it generated 10.hlsl, which contains both a fragment and vertex program. I split the file in two (one for the VP one for the FP), and added it to the content project.
Then I set the entry points, told the vertex program to use VS_2_0 and the fragment program to use PS_2_0.
I then created 10.program and added the gpu programs, and then edited the material script.
Well, it built, with Use Content Pipeline = Yes, but I still don't see the ninja. The log file reports no errors.

I'm still pretty iffy on shaders (and frankly I've got no idea what's going on inside that 10.program script) so perhaps you can see a problem in one of these.

Can anyone see a problem with these scripts?

hi doublea,

first, variables are case sensitive, so you need to take care if that (param_named_auto WorldViewIT inverse_transpose_worldview_matrix)
second, you'r trying to update variables which are not in your shader (eyepos for example).

and, can you post your code where you handle your ninja?

unfortunatly i dont have that much time today, otherwise we could meet IRC. if you have some time tomorrow, we can talk there.

//bostich

Thanks for the reply, I look forward to talking. I'd really like to get this project going.

Alright, I believe I'm fairly close here. A couple of questions.

First, in my .program file I set some default params

  Code:


       //vertex program
   default_params
   {
      param_named_auto World world_matrix
      param_named_auto View camera_position_object_space
      param_named_auto Projection world_matrix
      param_named_auto ViewIT inverse_transpose_view_matrix
      param_named_auto WorldViewIT inverse_transpose_worldview_matrix
      param_named_auto BaseLightAmbient float4 1 1 1 1
   }


now then in my vertex shader, it has the following variables to be initialized.

  Code:

float4x4  World;
float4x4  View;
float4x4  Projection;
float4x4  ViewIT;
float4x4  WorldViewIT;
shared float4x4  TextureMatrix0; //technique: None
float4 BaseLightAmbient;
float4 MaterialAmbient=float4(1,1,1,1);
float4 MaterialDiffuse=float4(1,1,1,1);
float4 MaterialSpecular=(float4)0;


now then in setting the default_params, I don't include MaterialAmbient, MaterialDiffuse, or MaterialSpecular, because they're already initialized. But do I need to set a value for TextureMatrix0? I'm kind of confused on the shared keyword, as well as I don't know what kind of value to be giving it.

Alright then, in my log, it tells me:
Invalid param_named_auto attribute - expected 2 or 3 parameters.

but I don't know what's asking for the parameters, and what parameters to give it

again, help would be greatly appreciated.

This is being quite the headache, and I apologize to anyone annoyed by my frequent questions in this.
Alright, I solved my shader problems (or so I believe), unfortunately my ninja has yet to make an appearance. I have been able to get particles to render properly however...

Anyway, in my log file it reports:

[11:49:55] No codec available for media with extension .mesh
[11:49:55] Mesh: Loading 'ninja.mesh'...
[11:49:55] Skeleton: Loading 'ninja.skeleton'...
[11:49:55] No codec available for media with extension .skeleton

is this the reason that my ninja's not loading?
