having costume presets is always good, but not the way it was in HS where you cant wear a swim bikini and a regular top/bottom at the same time right? i am pleased that we can finally do this at least
. also chara cards size would increase allot with ultra high resolution texture maps,mods and materials, it will also increase loading/folder scanning time. not to mention the unlimited accessory slots plugin, having all three costumes with 50+ accessories will just hang your computer when you open a folder that contains allot of characters, even if you have the best solid state drive and ram in the world. maybe its better this way ^^.
btw, best of luck to you and all game developers in F95 with the holiday contest
did you mean the coordinate cards menu but the "top box"? if that is the case, it looks like you don't have any saved costumes or "coordinates". while in maker, load any character and then click on the clothes icon from top left, then you will notice a "save & load" options from the menu on the left, it is where you save or load a character's costume in to a coordinate cards. you will be able to see them in game if you successfully save in maker.
it looks like it has been made in the studio (not in the mane game). there are allot of advanced plugins, tools and mods to compose even more complex scenes if you spend time creating them. i am not sure if the creator of this video has used the HS2 h-animations or made/edit them (i didn't spend much time exploring all stock animations).
there are few basic things about the studio
here in the studio/chara help thread, and i am planing to add more advanced/interesting guides about custom animations and camera movement like this one soon.
