Hi Aleksandra @~Ivy~ ,
“Would it even be advisable for me to attempt to render any of these animations?”
I wouldn’t recommend it.
With those specs it will probably take forever to Render an animation like that. The fact that is a (old) laptop, makes it even worse; it might not even survive (much longer)… You could just Render 1 Frame and see how long that takes you…That’ll give you a nice Render and also an estimate, how long it would take to Render the entire animation.
