Demon Tech repeater remake final
That's a lot of info to go through but here we go.
The iterative process


Iterating over

Loaded into unity3d, adjusted lights, did direct downscaling - doesn't look good

Lancoz downscaling looked ugly

Area downscaling via python scripting

Adding an triangle depth normal edge detection + downscaling "lineart" pass, this one via lancoz because of lack of color detail, which made it decent

Almost painterly enough

Unwrapped, added green demontech plasma corrosion

Finally added 50% mixed soft posterization
And finally everything together, with new sounds to boot.
Basic pipeline is this - I render at 640x400 in unity with sharpening, SSAO and posterization.


Then i render the plasma puff effect separately but without the alpha channel on a black background. Bring those over to a separate python script which creates alpha out of black channel, while also normalizing the color so it doesn't have colorbanding, resize it down.
Then I render the edges at 1280x800 separately, then bring it over to quite extensive python script which takes the sprite, scales it down, 50% multiplies it with the edges, then overlays it on top of the puff, after which it saves with the correct sprite name.
And that's pretty much it.
