The 3D Studio VIZ R3 Service Pack 1 (SP1) is a roll up of all the patches that were 
previously available for download as well as new bug fixes that were not previously 
available. Note that this Service Pack has been versioned subsequent to the release of the 
3D Studio VIZ 3vX Internet Extensions. The installation of the 3vX upgrade is not required 
to benefit from the bug fixes provided by this service pack. However, should you not have 
3vX installed currently and you wish to install it later, you will be required to uninstall 3D 
Studio VIZ and then reinstall, in order, 3D Studio VIZ, the 3vX upgrade and this service 
pack. If you have not already done so, we encourage you to upgrade to 3vX prior to 
installing this Service Pack. The 3D Studio VIZ Internet Extension may be purchased at a 
nominal cost from the Autodesk estore.

Note that SP1 is English version only and not intended to be installed with localized versions 
of 3D Studio VIZ. 

This Service Pack includes all the following previously released patches: 

Update Lightscape Lights (12/2/99)
This patch fixes an occasional problem where VIZ hangs while using Lightscape 
Photometric web files (.ies files) in Lightscape lights and a defect where the 
include/exclude properties of a Lightscape Light not persistent. 

Lightscape File Transfer (11/2/99)
This an update of the Lightscape Exporter for VIZ which allows VIZ designs and lights 
(including Lightscape Lights) to be exported into a Lightscape Preparation file. The 
exporter exports geometry, materials and lights for the current frame. Object and World 
Space Modifiers are applied during export. You can also use this plug-in to import 
Lightscape Solution files, preserving your Lightscape Lights data. 

Update: Filelink.dlu (11/2/99)
For all users who link to .DWG files, this update will fix problems related to reloading 
files that contain copied blocks. In our testing, we found that VIZ will link to but not 
reload files containing copied blocks. This update will correct the problem. 

Update Core.dll (11/1/99)
For customers experiencing resource problems in Windows 98 or Windows NT, this 
update will allow 3D Studio VIZ R3 to run using far less system resources. If you've 
experienced frequent memory or resource problems when running 3D Studio VIZ R3, 
this update should remedy the problem. 

Snap mode Macroscripts (10/13/99)
Enhancing 3D Studio VIZ R3's interface meant replacing many old buttons with newer, 
more familiar icons or text. The snap modes, such as 2D and 2.5D were removed to 
save on space. While you can access these modes via MAXScript, this Macroscript will 
allow you to add those buttons back in a toolbar.

Fix: Raytrace rendering (10/13/99)
This plugin fixes the raytrace renderer in R3 so that you can now render with raytrace 
reflections over time. If you have 3D Studio VIZ R3, English-language version, then 
you'll need this fix. 

Update: Light Lister Script (10/13/99)
The version of the Light Lister that shipped with the English language version of VIZ R3 
did not support groups of lights. This script fixes that problem.
