When it come to archviz rendering, one of the first thing to learn is to create good masks to retouch materials or objects individually in photoshop. If the most popular alpha mask allows you to cut out the entire rendering from his background, other type of masks (based on elements or objects) became essential for an efficient workflow in archviz.

I remember times where I did a second rendering with the same point of view, where every material was replaced by a self-illumated conterpart in order to save one or several DIY “masking pass” …a time consuming method, either on material editing or rendering. I even remember cutting out glass masks for buildings directly in Photoshop. Brrrrr :)

As a small case study, i modelled & rendered this Mac pro in approx 5 hours of work. The puprose was to mimic the aluminium case material and the studio setup used in Apple commercial stills.

Originally, it was tought to be lowpoly, but I’ve finally added many edges in the curves to catch the light as closely as possible. The buttons, fan grid and power plug remains lowpoly, but the mesh is easily ‘upgradable’ in a higher poly config if needed. I’ll share the model & setup soon when I found some time to pack this in a nice little zip…
