Hi,
I tried to runn CaveRenderPro as described in this thread using openjdk.
Unfortunately when I try to run the jar file I run into an error:

Error: Could not find or load main class de.caverenderpro.CaveRenderPro
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application

I use Linux Mint 20.3 and used the latest Cavernder Zip file.

Glück Tief
Tom
