PBR Materials ​

Physical Material panel

Physical Materials (PBR) control how surfaces look in your scene — their color, reflectivity, roughness, transparency, and more. This is the most detailed material editor in iJewel Playground and it uses a physically-based rendering model to produce realistic results.

Every metal, stone setting, enamel, ceramic, or glass surface in your jewelry model is controlled through this panel.

How to Open ​

  1. Click on any object in the canvas to select it
  2. Go to the PickingPicking tab on the right panel
  3. The Picker will show the material name, and the Physical Material section will open below with all its settings

Merging Materials

You can rename a material in the name field. If you select a different object and rename its material to the same name, both objects will share the same material — any change to one will apply to both. This is useful when applying library presets to multiple objects at once.

Physical Material ​

These are the top-level settings that appear when you expand the Physical Material section.

name
input
Material name. Rename for convenience (e.g., "Metal", "Pearl") or to merge materials by giving them the same name
wireframe
checkbox
Shows the polygon structure of the mesh instead of the solid surface
vertexColors
checkbox
Enables vertex color data from the model. Usually black by default — rarely needs to be changed
color
color picker
The base color of the material. Use the color picker or enter a hex value directly. The format is 0x followed by 6 hex digits (e.g., 0xe5b377 for gold) — keep the 0x prefix and change only the last 6 characters
Material color example
Custom color applied to metal
Metal material example
Gold metal material
map
image
Texture map applied on top of the base color. Requires UV unwrapping on the model. If your model has no UVs, enable Triplanar mapping below — seamless textures will wrap automatically

Rough/Metal ​

Controls how reflective and metallic the surface appears. Together with color, this defines the overall look of your material.

roughness
slider
How rough or smooth the surface is. 0 = mirror-like, 1 = completely matte
metalness
slider
How metallic the surface is. 1 = fully metallic (gold, silver), 0 = non-metallic (ceramic, plastic)
roughnessMap
image
Texture that controls roughness variation across the surface. When added, a roughnessMap Sampler section appears for positioning
metalnessMap
image
Texture that controls metalness variation across the surface. When added, a metalnessMap Sampler appears

Map Samplers

Whenever you add a texture map, a Sampler section appears below it with controls for scale, offset, and repeat. If you are using Triplanar mapping, you can ignore the Sampler — Triplanar handles texture placement automatically.

Roughness 0 — mirror-like
Roughness: 0
Roughness 1 — matte
Roughness: 1
Metalness 0 — non-metallic
Metalness: 0
Roughness 0.25, Metalness 0.80
Roughness: 0.25, Metalness: 0.80

Bump/Normal ​

Adds surface detail without changing the actual geometry. Bump maps use black-and-white images to create the illusion of height. Normal maps use specialized purple-tinted images for more precise surface detail.

bumpScale
slider
Controls the intensity of the bump effect
bumpMap
image
Black-and-white texture for surface bumps. When added, a bumpMap Sampler appears
normalMap
image
Purple-tinted normal map for detailed surface normals. Adds normalMap Sampler, normalScale (two inputs for X/Y strength), and normalMapType (Tangent Space)
displacementMap
image
Displacement texture that actually moves vertices. Adds displacementMap Sampler and displacementScale

Sheen ​

Adds a soft, fabric-like sheen to the surface edges. Can create interesting velvet or silk effects.

Clearcoat ​

Adds a secondary reflective layer on top of the base material — like a glossy varnish. Commonly used for ceramic, marble, and lacquered surfaces.

emissiveIntensity
input

Refraction ​

Controls transparency and light refraction through the material. Used for glass, crystal, and other see-through surfaces.

Override Environment
checkbox
Enables a custom environment map for this material only
Environment Intensity
slider
Brightness of the custom environment for this material
Environment Map
select

Download pmat ​

Download pmat

Exports the current material as a .pmat file. You can save your custom material settings and reuse them later or share them with others.

LUT ​

Apply a per-material Look Up Table for color grading. This works the same way as the global LUT post-processing effect, but applies only to this specific material.

Enabled
checkbox
Toggles the per-material LUT
index
select

Anisotropy ​

Creates directional reflections — like the elongated highlights you see on brushed metal.

Advanced section for clipping parts of the material rendering at the fragment level.

Flat Material ​

Renders the material without any lighting calculations — a flat, unlit appearance.

SparkleBump (NoiseBump) ​

Generates a procedural sparkle/noise bump pattern on the surface. For best results, use ready-made sparkle materials from the preset library rather than configuring this manually.

CustomBumpMap ​

Custom bump map settings for additional surface detail control.

ClearcoatTint ​

Adds a subtle color tint to the clearcoat layer.

SSBevel (Dev) ​

Per-material Screen Space Bevel control. This can also be configured globally from the Screen Space Bevel post-processing settings.

Per-material Bloom toggle. Allows you to enable or disable the Bloom post-processing effect for this specific material.

LayeredMaterial ​

Creates a beautiful two-tone effect where a second color appears in surface crevices and recesses. Commonly used for oxidized bronze, oxidized copper, patina, and antique finishes — the secondary color naturally accumulates in the grooves and hard-to-reach areas of the model.

Automatic UV unwrapping for the model. Enable this if you want the system to generate UVs automatically.

Object Actions ​

These buttons appear at the bottom of the Picking panel and affect the selected object.

Remove MaterialDuplicate ObjectWrap in ParentDelete Object
  • Remove Material — Strips the material from the selected object
  • Duplicate Object — Creates a copy of the selected object
  • Wrap in Parent — Wraps the selected object inside a new parent group
  • Delete Object — Permanently removes the selected object from the scene

WARNING

Delete Object is irreversible. There is no undo — the object and its data will be permanently removed.
