I’m currently using 2048x2048 texture sizes for almost everything. I’ll be putting it up on the marketplace at that resolution as well (almost all of the assets are at that resolution with only a couple examples that I have yet to show). That said, it’s easy enough to render at lower resolutions by changing the texture settings (the file size remains the same but you’ll get increased performance) as you’ll need far less texture resolution in an fps than for visualization purposes and even less in say a third person game.
