I promised SW would be back!
In regards to scene making and length of time, it depends. This SW scene came together remarkably fast. I'd say an hour or two from creation to output. Some can take longer if it requires I have to dress up a model like Roxy from Gen13. It's a lot of going through the mods I have and deciding what works or downloading new mods to achieve a look I desire. Environment and lighting came take up time as well. Luckily with this SW scene I had a beach hdri ready to go. Rendering can be short like a couple of minutes to an hour depending on the complexity and models in a scene. However, it depends on your rig as well for how fast you can render. I can I look at other creators here and some of their stuff is really gorgeous and I ponder how they achieved their scenes.
