MD3
- finished support for multi-part player models - skin files are now read - shaders are parsed, but not yet processed yet DefaultIOSystem - file size is now cached over multiple calls to FileSize() MaterialSystem - added AI_MATKEY_BLEND_FUNC property and the aiBlendMode enum to allow MD3 and Collada to pass transparency information correctly. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@346 67173fc5-114c-0410-ac8e-9d2fd5bffc1fpull/1/head
