Done in Blender. No texture painting or images. All shaders and incredibly simple shapes.
There's a little After Effects for vignette, lens dirt and colour correction (Which probably could have been done in Blender too).

Cheese World

cheers m8, yeah the 3d ghosting on the text was simply just rendering text in 3d then bringing that video file into any video program (I just happened to use Davinci Resolve) and duplicating the file a few times while offsetting the file in the timeline a few frames after the first, then just making the copies set to a blend mode like screen or something while lowering the opacity of eatch copy less and less till 0.

Thank you!! IIRC the rim light is just an area light behind them, though sometimes I do throw a fresnel on the shader or literally just paint lighting on in krita depending on the scene. That plus the heavy post processing with sharpening and everything makes it stand out extra. The carpet was just a plane with a hair particle emitter that I tweaked until it kinda had the look I wanted!

No, they are in a haze volume for a bit of depth. But sky plane would be cheaper to calculate though.
