Visualisation is how a project is sold before it exists. Good CGI does more than render a room, it carries the light, materials and atmosphere a studio has spent months designing. Demand for it is rarely steady: a competition, a pitch or a launch can create a sudden need for high-end imagery on a short runway. Independent CGI artists and visualisers who understand built environment work, not generic 3D, let studios produce striking imagery exactly when it matters.
