#!/usr/bin/env python
# pylddlib version 0.4.9.7
# based on pyldd2obj version 0.4.8 - Copyright (c) 2019 by jonnysp
#
# Updates:
# 0.4.9.8 Make work with LEGO Universe brickdb
# 0.4.9.7 corrected bug of incorrectly parsing the primitive xml file, specifically with comments. Add support LDDLIFTREE envirnment variable to set location of db.lif.
# 0.4.9.6 preliminary Linux support
# 0.4.9.5 corrected bug of incorrectly Bounding / GeometryBounding parsing the primitive xml file.
# 0.4.9.4 improved lif.db checking for crucial files (because of the infamous botched 4.3.12 LDD Windows update).
# 0.4.9.3 improved Windows and Python 3 compatibility
# 0.4.9.2 changed handling of material = 0 for a part. Now a 0 will choose the 1st material (the base material of a part) and not the previous material of the subpart before. This will fix "Chicken Helmet Part 11262". It may break other parts and this change needs further regression.
# 0.4.9.1 improved custom2DField handling, fixed decorations bug, improved material assignments handling
# 0.4.9 updates to support reading extracted db.lif from db folder
