I am using playground with typescript for longer time and now I have from day to day many errors reported. Its related to math and material function (specularColor???) that used to be working, can you look at it?

second question (its not an real error) is that approach to load external scripts from js is not working in TS. Is there any approach to get this working on TS? (example lower)
