Here are some examples of skydomes that I made using Terragen. Most of the skies I used were authored in Terragen and so were separate clouds that were later used as game assets as cards. Here is my experience with Terragen
Pros:
Art direct the skies with specific time of day and cloud composition.
Render cloud alphas for post work in photoshop or for in-engine materials.
Author HDR skies with a real dynamic range, which is important for in game lighting for some pipelines
Cons:
Still very difficult to control procedural outcomes of clouds. Limited access to education of software and lack of tools in Terragen make this difficult to overcome.
Very long render times. This usually limits the use of Easy Clouds to make the renders more manageable. It's not easy to convince management that you need a render farm in a game pipeline
Thanks to everyone who answered my questions over the years on the forum. The only way I learned was digging through old posts, asking questions, and dissecting tgc and tgd files. And I purchased clouds from NWDA store, but I wouldn't say those were necessarily better for learning. Expect me to ask more questions as I use Terragen for my next project.
