How to make renders for a visual novel

[Trinciapapere]

I'd like to build my own visual novels, i'd like to create something with the graphic settings like awam (a wife and mother visual novel) with the graphic in 3d and 3d environments but i can't understand/find the way to build the environments... i buyed character creator 3 and iclone 7 and i managed to learn how to create the characters with the renders for the characters... but how to create/make the environments? with programs should i use? where can i find some tutorial/material to learn it myself? i googled untill exaustion but didn't find anything that's not spam. tx in advance to all kind ansere!

ps: i managed to create my first work... its awfull, short, terrible... but hey it's just my first work! considering i know nothing at all about:
1) programming
2) building renders
3) python and so on

i'm a musician, not a painter nor a programmer. sorry for my awfull english, another thing i don't know for sure...
