It is difficult for me to understand your code, it is very confused.
Objects used in Boolean operations shouldn't be declared in a scene, but have to
be declared.
Here to you my help:
render.py line 2539

        for data_name, inst in data_ref.items():
            for ob_name, matrix_str in inst:
                use_in_boolean = 0
                for obj in bpy.data.objects:
                    obj_name = "OB" +
                    if obj.type == 'MESH':
                        for mod in obj.modifiers:
                            numberModifiers = 0
                            if mod.type == 'BOOLEAN':
                                numberModifiers += 1
                                mod_obj_name = "OB" +
                                if mod_obj_name == ob_name:
                                    use_in_boolean += 1
                            if numberModifiers > 0 and obj_name == ob_name:
                                use_in_boolean += 1
                if use_in_boolean == 0:
                    tabWrite("//----Blender Object Name:%s----\n" % ob_name)
                    tabWrite("//----Declare Blender Object Name:%s----\n" %
                    tabWrite("#declare %s =\n" % data_name)
                tabWrite("object { \n")
                tabWrite("%s\n" % data_name)
                tabWrite("%s\n" % matrix_str)

If I use Povray for a render, it is more convenient to me to use own version of
the exporter
But, if my version takes place to be for me, I offer it to another.
If users begin to ask very difficult texture map, developers of the official
version should reconsider the position.
