There is a way to show translucent background on a modal popup using Crosslight way.

Crosslight has UIBlurView which can be used with modal view using special technique. Currently the Crosslight development team is working to support this scenario. I'll get back to you as soon as I heard anything from the team regarding this scenario.

Hello Ryan,

Just a quick note that modal translucent view will be supported in the soon-to-release Crosslight 3.

Hope this helps.

I noticed BLUR View was added but how do I do Translucent Views?  I have my modal coming up and its blurred but I need it transparent.  Everytime I pop up the modal, it comes up as transparent, then the view with clear goes black.  When the view closes it reloads the entire back view.  

If I have the Blur View set, it doesn't reload the entire back view which is what I need but without a blur effect.

A how-to article which shows how to enable translucency visual effect in modal navigation iOS using Crosslight 3 is now available in here. This article also provides a runnable simple sample project. Could you please kindly test/run the sample and let me know whether it helps or not?

May I know why you need to reload the entire back view after the modal popup closes?
Look forward to hearing back from you.
