int ISurface::DrawGetTextureId( char const *filename )

Use this function before CreateNewTextureID to make sure you don't reference the same material with multiple texture IDs.

Sample

currentId = surface()->DrawGetTextureId( texturename );
if ( currentId == -1 )
{
	currentId = surface()->CreateNewTextureID();
	surface()->DrawSetTextureFile( currentId, texturename, false, true );
}
