+Blender IA/IGS exporter V2.0.158 HenningBR218 2010-04-21
+
+1. Summary
+----------
+The Blender IA/IGS Exporter 2.0, (Bigex), is a Python Plugin for the very
+powerful 3D modelling and animation suite Blender. Bigex allows the export
+into Kuju's own IA and IGS intermediate formats. These file formats are
+required to import 3D models into Rail Simulator and Rail Works.
+
+ Note: The Blender IA/IGS Exporter version 2.0 does not support the export
+ of animations into the IA format. This function will be
+ implemented in a later version.
+
+2. Copyright, Licence, Warranty, Contact, Credits
+-------------------------------------------------
+All rights, including the copyright, for the Blender IA/IGS export extension
+Bigex are owned by HenningBR218.

+
+The Blender IA/IGS export extension Bigex is subject to the GNU Public Licence,
+version 3 (GPL3) with the restrictions for commercial use as listed below. The
+full text of the GPL3 licence can be read on the net:
+www.gnu.org/licenses/gpl.html, http://www.gnu.de/documents/gpl-3.0.de.html
+
+The usage of the Blender IA/IGS export extension Bigex is allowed for creation
+of 3D models only, which are distributed without any form of compensation
+(Freeware). The usage for creation of 3D models which are not distributed as
+Freeware (Payware, Shareware, etc.) requires the express and written approval
+of the author (Contact: henningbr218 (at) b188 (dot) de).
+
+Each 3D model, created with the Blender IA/IGS export extension Bigex, with a
+certain count of vertices gets a special marking. This mark appears later in
+the 3D model in Rail Simulator / Railworks also. The evidence, that a certain
+3D model was created with the Blender IA/IGS export extension Bigex is
+therefore identifiable.
+
+The usage of Bigex is at the users own risk. The Author assumes no liability
+for damages, direct, indirect or consequential, to hardware, software or
+person resulting from the use of this script.
+
+Any error reports, questions or suggestions for extension of Bigex, can be
+raised in the German language forum of Rail-Sim.de:
+rail-sim.de, http://rail-sim.de/railsim/forumnew/index.php?board=8.0
+or in the English language forum of UKTrainSim:

+
+Many thanks for the help on manual translation, review and discussion to
+AndiS and Jeff Douglas (JADsHome).
+
+3. Further information
+----------------------
+Further information regarding installation, usage and also detailed background
+information are in the manual (Bogex_Manual.pdf)
+
+ Note: Nearly no one would be able to export a working model for RS/RW
+ without reading the manual. The possibilities for settings in
+ Blender are way to manifold.
