The OP was Italian.

But Spanish, Portugese, French, Italian et al (i.e. "The Romance 
Languages", derived from Roman Latin) are sufficiently similar that it 
is frequently straightforward for a speaker of one such language to read 
and absorb some of the meaning of a piece in another such language.

My (school) French and Latin permitted me to understand the general 
meaning of the OP's post. It's just that I don't know anything about 
Blender! :-)
