I’m really looking forward to shader/material packs as well. As someone who struggles with anything graphical (I have literally no artistic talents), I’m interested in those things, high quality assets. I’d really like to see something like what Unity has - I believe it’s part of the core now, but it started as the Universal Character Creator as a community asset. Basically it streamlined the process of creating characters (rigged and ready to stick on existing animations, since everything shares the same bones/rig). I’d love something similar, I need (for my own purposes) to be able to generate a lot of slightly different looking units, so something like that would be awesome and I’d love extra content to be easy to just plug in/drop in to it.
I’d love to see (although it may be more along the lines of things with material packs) some much more focused/diverse assets for things ‘every’ game needs, grass, rocks, moss, dirt paths, snow, etc.
I also look forward to complete drop in assets for whole systems like Time of Day + Dynamic Weather, and I look forward to seeing the for-profit communities work on things like alternative GI solutions.
I’d also like to suggest the marketplace be presented in a way that you can exclude/restrict to projects that are completely C++, completely blueprints or a mix of the two. It should be very easy to distinguish these things before a purchase or a download so that for example a C++ only user won’t waste his time with blueprint only assets or vice versa.
