PBR is not a visual style. It is a lighting model. You can shade a painted, cartoon surface with the same energy-conserving BRDF you use for photoscanned oak. The difference is what you put in the maps, not whether you “use PBR.” If a stylized scene looks muddy or plastic, the maps are usually fighting the light instead of supporting the art direction.

PBR is a lighting model, not a style

Physically based rendering assumes albedo contains no lighting, roughness controls microfacet spread, and metals reflect environment color instead of a separate diffuse lobe. Those rules still apply when you flatten color, exaggerate edges, or drop photographic grain. Blender’s Principled BSDF, Unreal’s Default Lit, and Unity HDRP Lit all expect the same inputs. If you need a map refresher, read the complete PBR texture guide.

What changes is contrast and frequency. Realistic packs keep photographic variation: pores, wear, dirt in crevices. Stylized packs reduce that frequency so shapes read at a glance. Both can be CC0. Locker3d offers free CC0 photoscanned textures that are realistic by default; you can still grade those maps toward a stylized look without leaving the metalness/roughness workflow.

How realistic PBR maps behave

A photoscanned wood or metal set usually includes albedo with subtle hue shifts and no baked shadows, roughness with fine noise that breaks up highlights, a tangent-space normal for grain and scratches, and metalness that is nearly 0 or 1. Use 2K for most hero props and 4K only when the camera is close; see the PBR texture resolution guide. Light with an HDRI so roughness and metalness have something real to reflect. Setup notes live in HDRI and PBR lighting.

Watch dark dielectric albedo and flat roughness: both look worse under GI than in a studio HDRI.

How stylized PBR maps differ

Stylized materials still need roughness variation, just at a larger scale. Instead of wood pores, paint three roughness bands: worn edges, mid panels, and recessed dirt. Keep albedo closer to a limited palette. Flatten or omit the normal if the silhouette already carries the detail; a strong normal on a toon-facing shader creates noisy spec.

  • Albedo: four to eight colors, a slight gradient, no photo grain.
  • Roughness: 0.35–0.7 for painted surfaces; 0.15–0.3 for enamel or wet ink.
  • Normal: optional. If used, keep it low frequency and intensity 0.2–0.5.
  • Metalness: still binary. Gold trim is 1. Cloth and plaster are 0.

Do not fake metal with a bright albedo and low roughness on a dielectric. Image-based lighting will expose it immediately.

When to mix both in one scene

Archviz and product shots stay realistic. Stylized games and motion graphics stay stylized. The hard case is a realistic environment with a stylized hero, or the reverse. Share one lighting setup. Match average roughness so a chalk character does not sit on a mirror floor. Grade albedo together: if the world is desaturated, desaturate the hero maps too. Reuse tiling wood and metal from a CC0 library for set dressing, then hand-paint the hero.

Browse the Locker3d texture catalog for the realistic half, then paint over roughness in your 2D or material tool for the stylized half. Because Locker3d files are free CC0, you can flatten, repaint, and ship them commercially. See what you can and cannot do with CC0 textures.

A practical checklist before you lock the look

  • Confirm color space: sRGB albedo, non-color for roughness, normal, and metalness.
  • Check albedo luminance. Dielectrics should sit roughly 50–240 sRGB, not 10 or 255.
  • Preview under at least two HDRIs (studio and overcast). If the material only works in one light, the maps are compensating for lighting.
  • Decide normal intensity before you start painting wear. Changing it later rewrites the whole read.
  • Keep licenses simple. Free CC0 maps let you iterate without tracking attribution per file.

If you are unsure which way to go, block with a mid-rough dielectric and a metal, then replace maps. Style lives in the textures. More notes are on the Locker3d blog.

Frequently asked questions

Can stylized art still use PBR textures?

Yes. PBR is a lighting model, not a visual style. Stylized materials still use albedo, roughness, and optional normal and metalness maps. You just paint flatter color, larger roughness shapes, and less photographic noise.

Should I use photoscanned textures in a stylized scene?

You can, if you grade them. Lower normal intensity, posterize or saturate albedo, and paint broader roughness. For a fully painted look, start from a limited palette instead of a raw scan.

What is the fastest way to test both looks?

Keep one shader. Swap only the maps and preview under two HDRIs. If the material only works in one light, the textures are compensating for lighting instead of describing the surface.
