Multi Unit Project Documentation

• Use of Data Tables to store information. These can then be used in multiple scenes. This also makes navigation within the Info Map easier
• Preparations for the use of remote data and reports saved and read from Google Sheets. A plug-in is required and a couple of files need to be replace.

There will be a tutorial available soon on how to make the changes to get remote access to the data used and changed within the UI3.

Unreal 5 - all versions

• implemented group totals and level cost info widget and CSV export

• The Variation Actor has a price array for each variation. This can be used instead of adding an Info Object for each variation.
• The first info array element will be used if the current variation doesn't have an array element.
• The price will be listed next to the variation name.
• The cost data can be exported as a CSV table.

Unreal 4 requires baked lighting most of the times. This makes changing static meshes in the scene difficult. I recommend using Unreal 5 instead.

• The Variation Blueprint got an Object Info section too
• A JSON data file for the inventory list can be created. The CSV and HTML formats are now working proper log (requires easy file manager plugin to create file)
