The technology:
Stylized architectural images that deliberately move away from photorealism — hand-drawn appearance, ink and wash, pencil sketch, watercolour, and hybrid artistic styles. Produced from 3ds Max geometry with V-Ray render passes and post-processing in Photoshop or DaVinci Resolve.
Non-photorealistic rendering (NPR) is architectural visualization in a deliberately artistic register. The building and its geometry are still modeled in 3ds Max — the shapes are correct, proportions are accurate, spatial relationships hold — but the final image looks like a hand drawing, a watercolour study, or an ink sketch rather than a photograph.
The technique is chosen when photorealism would send the wrong signal. Early-stage competition entries, conceptual masterplan presentations, and projects where the design intent matters more than the material detail benefit from images that read as ideas rather than finished products.
When NPR fits and when it doesn’t
The choice between photorealistic and non-photorealistic output is a communication decision, not an aesthetic preference.
Choosing the rendering register
| Photorealistic | Non-Photorealistic | |
|---|---|---|
| Signal to viewer | This is what it will look like | This is the idea and spatial concept |
| Detail level | Every material, fixture, and finish visible | Structural and spatial emphasis; detail suppressed |
| Design stage | Developed or final design | Concept, schematic, competition entry |
| Client expectation risk | High — clients may read the render as a contract | Low — artistic register signals proposal, not commitment |
| Competition entry use | Can feel corporate or generic at smaller budget | Distinctive character; sets scheme apart from photorealistic entries |
| Post-processing time | Standard V-Ray post | Additional stylization layer, but faster per image than full photorealism |
Style range
Hand-drawn / ink line — wireframe-adjacent, clean linework with selective hatching. Communicates precision and craft. Useful for technical presentations and competition boards where geometric clarity matters.
Pencil sketch — soft, textured, slightly loose. The appearance of a thinking drawing rather than a presentation drawing. Works well for early-stage residential and renovation work.
Ink and wash — linework with tonal areas blocked in with flat or graduated tone. A classic architectural presentation technique. Legible at small sizes, scales well to presentation boards.
Watercolour — soft colour washes over line. Works particularly well for landscape-integrated projects, heritage contexts, and cultural buildings where a warm, human quality is appropriate.
Mixed media — NPR elements combined with photographic textures. A realistic sky behind a sketch-rendered building; photographic materials applied to a line-rendered structure. This hybrid approach retains artistic character while grounding the image in physical context.
How it’s produced
The 3D model is built and positioned in 3ds Max in the same way as a photorealistic render. The difference is in what comes out of V-Ray and how it’s processed:
Render passes — V-Ray outputs separate passes: wireframe lines, ambient occlusion, depth, surface normals, material ID. These are the raw material for stylization, not the finished image.
Post-processing — the passes are composited and stylized in Photoshop or DaVinci Resolve Fusion. Paper textures are overlaid. Line weights are adjusted. Colour is introduced through wash layers. The level of stylization is calibrated to the chosen style and the presentation context.
Consistency across views — for a series (multiple elevations, interior views, site context), a single style template is established on the first image and applied consistently across the set.
What we need from you
| 3D model | The same model used for standard rendering. NPR is a post-processing style — the underlying geometry still needs to be correct. |
| Style references | Examples of the visual register you're targeting. An architectural drawing you admire, a competition entry, a magazine illustration. Style without a reference is harder to calibrate than style with one. |
| Intended use | Competition board, client presentation, social media, print publication. This affects resolution, colour profile, and how much fine detail the stylization needs to carry. |
| Viewpoints | Same as standard rendering — plan, elevation, perspective view, aerial. NPR can be applied to any camera position. |
