This is a fully textured exterior scene ready to render with Corona Renderer for Cinema 4D.
All objects present in the scene were created by me, using the most varied techniques to create original and themed objects, recreating objects of design of great Italian and international designers, all the furnishings: bedroom, bathroom, kitchen, living room and dining room, with all design models recreated from scratch.
Oh, it’s not smoke, it’s some odd color compression artefacts, not sure if from image compression, or possibly from denoising dark areas of low contrast. The main body of the black teapot for me has significant pixellated color banding.
Looks fine on behance! Something about image compression here in that case, either in the source image, or something the forum has done to it on upload
