How to use old .HDR's from Hypershot? What is .HDZ?

[nmeyer]

I tried to copy and paste the .HDR environments from my old Hypershot (and my trial of Bunkspeed Shot which is garbage ) but they wont show up in Keyshot.  All of Keyshots environments are .HDZ's.  What is this file format?  How to do I get my old .HDR's to show up?  No offense to Keyshot but although the program is far superior,the new environments are gloomy not as good as the old ones.

Thanks for the help!

you need to right click inside "environments" and choose "rescan library directory" or "add files to library"
