VN (DOUBT) What is the name of the Engine used in Harem Hotel / Family Fun?

Hello, this is my first post, so greetings to all . I'm very interested in creating VNs, but since I have a low-end PC, DAZ3D takes a long time to render. I have seen that there are many games created with this graphics engine (Like Harem Hotel, Family Fun, Alex Choice, Chemical Change) and I think it is much lighter than DAZ.
DOES ANYONE KNOW THE NAME OF THIS ENGINE?​

Thank you very much, I have searched everywhere. The only thing I would have to do once the app is installed, create the characters, take a screenshot from there and take them to Renpy, right?​
