Clay render

A clay render is made by temporarily replacing every texture and material in a scene with one uniform, matte, usually light-colored material. The name comes from clay models. The result shows only form, massing, shadow and the way light moves through the space, with no color or texture to distract the eye.

What clay renders are used for

During design, architects and clients can discuss massing and proportion before committing to materials. For the visualization team it is the cleanest way to test lighting: sun angle, window light and shadows read clearly without materials getting in the way. Because clay renders are quick, comparing several camera angles or times of day is easy. Modeling problems, such as overlapping faces or gaps at junctions, also stand out immediately.

As a presentation style

A clay render is not just an in-between step. It is also used as a calm, sculptural style in competition boards, concept presentations and portfolios. Sometimes one element, such as the glazing or the trees, keeps its real material while everything else stays white, which draws attention exactly where you want it.
