Thursday January 01, 1970

Grand Theft Auto V

Thursday January 01, 1970

We added support for highly
requested PSO file – pedpersonality.ymt. As always with OpenIV this is means,
you have all the names and string values in file. You can edit pedpersonality.ymt
in inbuilt OpenIV Text Editor or export and import it as META/XML. The “Title Update”
notification for outdated update.rpf in “mods” folder now also shown
in read only mode. In previous versions, it was shown only in edit mode and some
people might miss it because they do not have edit mode enabled by default.From now on, text based .dat
files, .gxt2 files and .nametable files will be opened in OpenIV Text Editor.We added support for new
version of carcols.ymt from Arena Wars update.We added support for new
shaders in openFormats for GTA V models from Arena Wars update.We added new names for audio
tracks from Arena Wars update.We added new names for objects
and models from Arena Wars game.

XML Syntax validation in OpenIV Text Editor

We added new useful feature into OpenIV
Text Editor – XML Syntax validation. This feature was originally planned for
text editor from very beginning but was postponed due to time limitations. When
you open XML, META or PSO file in OpenIV Text Editor you will see new XML
button on the Home ribbon tab:

When you click on it, OpenIV will validate
XML syntax of your file and let you know if you have any errors or not:

In addition, when you try to save file
OpenIV will automatically validate XML syntax for you. OpenIV will not allow
you to save PSO file with invalid XML syntax:

However, for basic XML files you will
decide whatever you want to save file with errors or not:
