mudmask 3d modeling and level designing for C2? blender is your best choice for 3d modeling... you wont need a insane computer to use it, you can animate things very fast, and export any models for you C2 3d game. as for level designing C2 top view thats how i do it, first visualize the concept of the map lets say in ur mind, then load the json files... or the models exported from the blender, then edit your level in a TOP down view using C2 normal editor, by default when u lead your game, if your using q3d physics the world gravity is on Y axes which is the wrong depth for c2, so you only need to tweak that on the start of layout events, the movement axes will be the same as before, just youl only need to raycast so it recognizes the Z distance, you can develop a Mario 3d World like game very fast, if you dont overreact with webgl effects, and you use only 3d models/3d sprites.
Note that : using normal sprites will only increase the user minimum spec requirements. since the gpu card and game engine will have to double render the objects in 2d and 3d in the same time, since both are meant for different usages, but you can use a 3d sprite, and make it act as a 2d sprite.
im currently working on 3 projects, a personal one, this fps kit thing, and a platformer 3d world, and im telling u the 3d games, are working faster, and are easier to make then i was expected, sometimes easier to solve problems then in the 2d ones. For now they are pc games meant, but im running and building them on a garage "pc" very low spec.. if works on mine, will run like an 24bit game software on this days computers, and im pretty sure i could compile them and optimize the engine of the game to make it work for online hosting sounds crazy but is real. i mean you cant expect the same performance boosting like a game made in unity... cause c2 isn't meant for 3d games, its meant for 2d, and for that i think is why the 3d games made in it, kinda are slowing down some times, the 2d is overlapping in some parts, and forces the boxweb physics that is implemented... but thats another story so i guess... that answers it? for 20/30 cad to have full access on 3d games made easy is worth to buy the plugin.
dheart88 they where possible before also, just they where more of fake 3d (2.5) .. now they are full 3d .. unity /blender like awesome right?
