Hello, I am running Sketchup 2015 on wine with Ubuntu 18.04. I installed SketUcam 1.4 extension without issue but when I click on the Parameter icon the panel opens but it is empty. There is nothing at all in the panel.
you need to use compatible dialogs SketchUcam: HOWTO set default options OR you need to install IE extensions for WINE, part of the winetricks package IIRC. this is because the normal parameter dialog is actually a web page that is rendered by Sketchup using the IE engine.
