Hi Michael, unfortunately there is a whole lot more to integrating rendering in MoI than just the engine alone. There is a whole lot of UI and workflow design that would need to be done as well. Because of the substantial amount of work and planning involved, it's not likely that a photorealistic render engine like that would be feasible to implement in MoI v4, sorry.

I would like to integrate some kind of rendering in MoI at some point, but at first it will probably be a very simple renderer and not focused on photo-realistic results like that.

There are also already many different rendering programs you can use in combination with MoI to do renders, that's another thing that tends to make an integrated renderer less of a priority for MoI as well.
