When I add skeleton file, material appears funky?

[Nickak2003]

I made a model in blender, exported with blender2ogre. The model loads in ogre and shows the material and texture perfect, until I add a skeleton file to the directory then the material appears mostly black. I've looked at the xmls and cant figure it out.
Here is with the .skeleton in the directory:

Here it is when no .skeleton is present:

Heres the skeleton file:

Code: Select all

<skeleton >
  <bones >
    <bone id="0" name="base" >
      <position z="0.000000" y="-2.580261" x="0.000000" />
      <rotation angle="0.000000" >
        <axis z="0.000000" y="0.000000" x="1.000000" />
      </rotation>
    </bone>
    <bone id="1" name="boneexhaust" >
      <position z="0.000000" y="2.580261" x="0.000000" />
      <rotation angle="0.031757" >
        <axis z="-0.000310" y="-0.019528" x="-0.999895" />
      </rotation>
    </bone>
  </bones>
  <bonehierarchy >
    <boneparent parent="base" bone="boneexhaust" />
  </bonehierarchy>
</skeleton>

Heres the vertex format

Code: Select all

<mesh>
    <sharedgeometry vertexcount="702">
        <vertexbuffer positions="true" colours_diffuse="False" texture_coords="1" normals="true">
            <vertex>
                <position z="0.981362" y="0.679798" x="0.000000"/>
                <normal z="0.158038" y="0.961851" x="0.223310"/>
                <texcoord u="0.815043" v="0.647575"/>
            </vertex>

OK i figured it out, the problem was that blender2ogre was exporting the texture coords in buffer0, they apparenrtly need to be in buffer1 for some reason, separate from the position/normals. I modified the blender2ogre script to do this. Is blender2ogre is defunct? If anyone is interested in the modifications let me know

Which version of Ogre where you doing this with? Having only 1 vertex buffer should be fine in Ogre 1.x, and skeletons shouldn't affect it.
What was the material like? Was it using a hardware skinning material? Shaders?

Thanks for the response!

It is ogre 1.9. I just rebuilt everything just to check (this link, download button, https://bitbucket.org/sinbad/ogre/src/4 ... ?at=v1-9-0 ). It doesn't seem to work with one vertex buffer. Here is my material:

Code: Select all

material jetmat 
{
    receive_shadows on 

    technique
    {
        pass jetmat
        {
            ambient 1 1 1 1.0
            diffuse 1 1 1 1.0
            

            texture_unit 
            {
                texture jet1tex.png 0
                tex_address_mode wrap
                scale 1.0 1.0
                colour_op modulate
            }
        }
    }
}

However, I have noticed that both ninja and robot also have a separate uv buffer.

LOL. So, I click that link, the text says 1.9, but the download is actually for 1.10 unstable... according to the cmake output which i didnt notice until recently. Ya, it wasnt 1.9, thanks!

I had this as well (Blender 2.79, Ogre 1.12, Windows 8.1, Visual Studio 2019). I used the ogremeshupgrader with the -i option and allowed it to reorganise the mesh vertex buffers. The "automatic" option puts the texture coordinates in buffer1 instead of buffer0. From then it worked fine.
