Note:

After adding the. mesh to a node for the first time, only the model is drawn, but there is no skin, because the material is not properly loaded.

To load materials correctly, ogre: resourcegroupmanager: getsingleton (). initialiseallresourcegroups ();

Must be called.

In addition, locateresource (read resources_d.cfg) and the above loadresource must be called after the Ogre: rendertarget * renderwindow is created.

In addition, the DLL plugin_participant fx_d.dll is required, which is used in initialiseallresourcegroups.
