Multiple Techniques with iOS and Ogre 1.9

[Carlyone]

Hello,
I am currently attempting to make use of the schemes in the ogre materials.

I have setup the viewports to switch between the material schemes and added the scheme into the RTShaders handleSchemeNotFound method.
However the model just disappears when I switch it from the default to "Wireframe" as I've called it.

The material looks like this:

Code: Select all

material 1391436092_2_Translucent_Glass_Gold
{
  technique
  {
    scheme Default
    pass
    {
      scene_blend alpha_blend
      depth_check on
      depth_write off
      ambient 0.0 0.0 0.0 0.600000023841858
      diffuse 0.0313725490196078 0.788235294117647 0.945098039215686 0.600000023841858
      specular 0.0 0.0 0.0 0.600000023841858 0.0
      emissive 0.0 0.0 0.0 1.0
      // texture size: 24.0, 24.0
      texture_unit
      {
        texture 1391436092_1_Translucent_Glass_Tinted.jpg
      }
    }
  }
  technique
  {
    scheme Wireframe
    pass
    {
      ambient 0.8078431372549 0.86274509803922 0.15294117647059
      diffuse 0.8078431372549 0.86274509803922 0.15294117647059
      polygon_mode wireframe
    }
  }
}

It seems that the second technique is never parsed, I added a listener to the resources and on resourceComplete there is only one technique on the resource.

Have I missed something?

Hoping it's something simple

Update:
Ok the resource does parse correctly, I checked it further up the chain in my Ogre::MaterialManager::Listener in the handleSchemeNotFound method and there are definitely two supported techniques.

The model is still completely disappearing when switched to the "Wireframe" viewport material scheme and that has me stumped.

Any ideas?

Kind Regards

If you're using RTSS have you logged what the created techniques look like? I use Ogre::MaterialSerializer so I can see what RTSS has done since it gets a bit confusing for me to keep track of

Hi,
Thanks for the response.
I have created a subclass of Ogre::MaterialSerializer::Listener but I'm not really sure how I go about adding it to the material serialiser, I read the comments in the code but it's still not really clear. Would you mind providing a bit of guidance on adding the listener?

Kind Regards

I don't use a Listener. I just iterate over the materials in the MaterialManager a bit like this:

Code: Select all

        Ogre::MaterialSerializer sNew;
        for(Ogre::MaterialManager::ResourceMapIterator it = Ogre::MaterialManager::getSingleton().getResourceIterator();it.hasMoreElements();)
        {
            Ogre::MaterialPtr m = it.getNext().staticCast<Ogre::Material>();
            sNew.queueForExport(m);
        }
        sNew.exportQueued(<your path>);
