 # BlenderUmap
 A Java tool to export Fortnite .umaps and a Python script to import it.
 
+## Disclaimer
+This tool was made to fulfill my curiosity about exporting a Fortnite building into Blender back in May 2020, and I did not plan to support this for long term. Although I rarely release some updates to fix some breaking stuff with Fortnite (and/or incorporating enhancements on the underlying parser), **no support will be given when it's about small issues, failing to use the tool properly, or adding support for more games.** Take your time to read the stuff below, and thank you for your understanding.

 ## Usage
 * Before running the tool you need to have 64-bit Java installed. [Get it here. (choose 64-bit Offline)](https://www.java.com/en/download/manual.jsp)\
   **32-bit Java won't work with this tool!**
