This idea has been merged into another idea. To comment or vote on this idea, please visit C3-I-55 3D boxes with sprite textures (2.5d essentially).
I am not talking about a full 3D engine. What I am talking about is (and I dont know the technical terms)
It would be like a sprite object that you could drop into the game. But instead of containing a 2D sprite it would contain a 3D model.
However, for all purposes the game would treat it as 2D sprite with a 2D collision box.
It would likely only need to be orthographic 3D i.e. no perspective but maybe that could be an option.
Instead of 2D animation frames you would have poses, rotations, model swaps.
There would be basic lighting options.
But the main thing is that there would be shader options to set pixel resolution with restricted colour palette, or a cell shaded option. This would be real time rendering in the style that you need.
This is one of the big reasons companies use 3D engines for 2D games is the work involved in updating 2D pixel art animated sprites
This guy is trying to do the pixelart shading here.
But to have this a feature in Construct 3.... OMG
