I am using this program as a reference builder for oil paintings.
This is far faster than building scene collages in photoshop. And provides correct light and reflection reference which is very difficult to get otherwise. I now spend far less time hunting for images and more time painting. Love it.
Only two caveats.
1: I wish I could import my own models, specifically human analogs I've created from other programs like DAZ Studio. The developer has mentioned they are looking into this in future updates.
2: I wish the sky had an Alpha channel PNG option. Then I could use reference scenes in layers on top of other sci-fi paintings I've done. Because, as it stands, I currently spend a few hours with tedious masking around every leaf and tree.
With those two options it would be perfect. Still, this is probably my favorite reference art tool. Even if it wasn't meant to be one.
