I just opened it the file is not blank.

right click "save link as"

and then if you want to see it open it up in notepad but it does work

here is the code I dont know how successful you will be copying and pasting and resaving it but its there if you want to try.

# Change List / History
#
# 0.0.1 - Write out texture filename and path for ASE submaterial tag *BITMAP "..."
# 0.0.2 - Generate collision mesh automatically. Copy geometry into another GEOMODEL object prefixing object name with UCX. Collision was too complex.
# 0.0.3 - Removed non-essential parts for Muvizu input (import, and all export except ASE functions).
# 0.0.4 - Limited output to components only. Remove all handling of groups.
# 0.0.5 - UI to allow selection of one component as geometry and one component as collision.
# 0.0.6 - Renamed classes and methods to avoid dependency or interfearance with the original plugin.
# 0.0.7 - Refined UI to reduce and report errors.
# 0.0.8 - Updated about text and source comments for completeness.

UI.messagebox("Muvizu ASE Exporter

Original work by Raphael Couturier (HardPCM) with HSKP2UNR
HardPCM's Google Sketchup Exporter to T3D/PSK/ASE/OBJ format
for UT3/UT2K4/UT2K3/UT99 game engines. Version 0.9.8 May 26nd 2009
was used as the foundation. The aim of this update is to provide
a more optomised exporter for use with Muvizu (http://www.muvizu.com)

Change List / History

# 0.0.1 - Write out texture filename and path for ASE submaterial tag *BITMAP "..."
# 0.0.2 - Generate collision mesh automatically. Copy geometry into another GEOMODEL object prefixing object name with UCX. Collision was too complex.
# 0.0.3 - Removed non-essential parts for Muvizu input (import, and all export except ASE functions).
# 0.0.4 - Limited output to components only. Remove all handling of groups.
# 0.0.5 - UI to allow selection of one component as geometry and one component as collision.
# 0.0.6 - Renamed classes and methods to avoid dependency or interfearance with the original plugin.
# 0.0.7 - Refined UI to reduce and report errors.
# 0.0.8 - Updated about text and source comments for completeness.

Special thanks to:

- Raphael Couturier (HardPCM) for the original work.

- Jim Skivington for testing the early attempts at the changes.

How to install:

filename is: \"MuvizuASEExporter.rb\"
and put it in the directory like
\"C:\Program Files\Google\Google SketchUp X\Plugins\"

How this works:

Everything is in inch OK!!!
So 512 inch unit = 512 unreal unit.
This apply to the model size and the material size.

Muvizu supports both single and double sided objects. This means you do not need to worry about WHITE or BLUE mode for faces, however to achieve the best results from modelling for a games engine it is recommended that use only use signle sided objects. The recommendation is for WHITE (when all faces of your object look WHITE on the outside). If you do not then some faces will only be visible inside your object. Each face needs to have a texture applied to it.
