AfterTheFlood/SeeMore script licenses

Hi, there are lots of useful scripts in AfterTheFlood and SeeMore like water/foliage/wire/leaves, to make really nice scenes. Are they MIT license too, so they can be put in MIT licensed repos? I couldn’t figure out which license is attached to them.

On a related note, could PlayCanvas set a standard license like ISC, MIT, BSD or whatever to the tutorial scripts?

E.g. WebGL Lab has lots of code which I would like to use, but there is no license statement anywhere
