In the Unreal Four Engine, when using the "Web Browser" plugin, you need to make the web page transparent.

In the Unreal Four engine, when using the “web browser” plugin, you need to make the webpage transparent. When I check “Support Transparency”, it is not transparent. I don’t understand. Is there a special color that will make it transparent or how? Can the web page be transparent? thank you very much

Same question here!!

Found the solution, run this js code after loading the page:
document.getElementsByTagName(‘body’)[0].style.overflow = “hidden”;
document.getElementsByTagName(‘body’)[0].style.background= ‘none’;

And use this code to set the transparency on the fly with the changes on the render opacity:
document.getElementsByTagName(‘html’)[0].style.opacity = “0”;
