We're using Unity (Quarter Circle Games). I'm happy to give an interview and some of my lighting/PP techniques. You can view out game here: https://store.steampowered.com/app/907500/The_Peterson_Case/
This is a fan project, like the Lord Inquisitor was. GW has absolutely nothing to do with it!
The Kumo team has shared their first dev blog post that focuses on the production of clouds in UE4.
This first post shows the way they handle physical clouds with performance in mind while still maintaining quality and options for a variety of shapes. Basically, clouds can be quite tricky because you can’t make them too sharp or plain as they will not look like “fluffy balls of perfection” and that is a challenge to deal with.
The problem here, though, is that it’s quite expensive, so it’s not perfect when generating an entire world and ocean with fluffy clouds.
What is the solution here then? Make sure to follow this link to find the post with an answer. Don’t forget to discuss the team’s approach in the comments below.
