[fixed]Texture error in Ogre mesh loader in irrlicht 1.4.2

When you load ogre mesh files into irrlicht 1.4.2, you will find that the textures are wrong. The reason is to confuse Index field and Source field in struct OgreVertexElement.
Fix method:
replace "if (geom.Elements.Index==geom.Buffers[j].BindIndex)" with "if (geom.Elements.Source==geom.Buffers[j].BindIndex)" in line 411, 429, 446, 481, 499 and 516 in the file "COgreMeshFileLoader.cpp".

Opened in the tracker.
Could you make some of your resources available, please, so that we can replicate the problem and validate the fix.

You can test it with ninja.mesh from samples in Ogre SDK. This will replicate the bug in the function COgreMeshFileLoader::composeMeshBuffer.
Then you can find a mesh with multiple submesh. This will replicate the bug in the function COgreMeshFileLoader::composeMeshBufferLightMap.

I can and I could, if I had the Ogre SDK.
Can you help us to help you by just posting the meshes somewhere. Pretty please.

Thanks for the ressources, that helped a lot. Current SVN/trunk (i.e. Irrlicht 1.5) has this fixed.

This fix seems a problem with some .mesh files. Please download the file "ember-media-0.5.5.tar.bz2" from
http://www.worldforge.org/dev/eng/clients/ember. Unzip it in a directory.
With the 09.Meshviewer example, load the following mesh and then the associated texture:
shared/common/3d_objects/plants/trees/models/oak/oak_youngA.mesh,
shared/common/3d_objects/plants/trees/textures/oak/D.png
It works well with 1.4.2 SDK but it does not work anymore with 1.5. Texture coordinates seem to be broken.
I recompiled the 1.5 lib with the 1.4.2 COgreMeshFileLoader.cpp file, and it worked again.
