Hey thank you so much! I love to hear there are some folks out there who are really enjoying it, it means a lot to me! I wanted to do a superhero VN specifically for that reason, funnily enough...
I use a program called Daz3d - it's super easy to pick up and if you're new to the whole rendering thing, I highly recommend it! It can be a little costly to get started, but I've found it very enjoyable to work with. Thanks again for reaching out! Hope you enjoy the future updates of the game!
