noob with honeybee

so after a lot of using ladybug i finally stepped into honeybee. nice videos on youtube, but quite outdated and i'm getting lost easily.

for instance, in "honeybee workshop part 1" many things are outdated and changed since then:

1)i'm not even able to generate "sky with certain illuminance level" ...the default value has disappeared through the versions and i don't know what to put... 1? 0,5? ..boooh..

2) how do I apply materials to objects? the "generic material" component is gone, and the video starts with that, so i'm stuck from the beginning

3) and then i get a strange error when attempting to generate the RAD file. unfortunately i'm using the machine of a colleague and the message is notified in the native language and can be translated as "the specified key was not present in the dictionary".
this appears immediately after i toggle "write rad" to True.
Maybe does it have something to do with the fact i didn't set up materials because couldn't figure out how?

thanks for helping!

ps i went to check and it seems that a folder has been created with a .sky and .typ file
