Rubens Knowledge Base

To ensure your products look consistent and realistic across all devices, Roomle Rubens uses Physically Based Rendering (PBR). This is a digital standard that ensures materials like velvet, oak, or brushed steel react to light just as they would in the real world.

PBR stands for Physically Based Rendering. Unlike older 3D methods that "painted" shadows and highlights onto a surface, PBR defines the physical properties of a material. The Rubens engine then calculates how light bounces off that surface in real-time. This ensures your "Natural Oak" finish looks accurate whether it’s viewed in a bright showroom or a dimly lit living room via AR.

A "Material" in Rubens is a combination of different "maps" that define its physical behavior:

This is the raw color or pattern of the material without any shadows or shine.

Neutral Lighting: If you are providing photos, they must be taken under flat, neutral light.

Clean Patterns: Avoid "baked-in" lighting or shadows in the image, as the Rubens engine will calculate these dynamically.

This defines how "microscopically rough" a surface is.

Matte vs. Shiny: A low roughness value makes a surface look like glass or polished chrome. A high roughness value makes it look like soft felt or raw wood.

Reference Photos: It is very helpful to provide a photo of the whole product so our team can see how the light naturally hits the finished surface.

This creates the illusion of depth without adding complex 3D geometry.

Tactile Feel: It tells the light to bend as if small bumps like leather pores, wood grain, or fabric weaves were physically there.

If you are requesting the Roomle 3D Service to create materials for you, please provide the following to ensure the highest accuracy:

3D models need to know exactly how large a pattern is to display it correctly.

The Ruler Trick: When taking a photo of a material (like a fabric swatch or wood plank), place a ruler or measuring tape directly on the surface. This allows our team to calibrate the digital scale perfectly.

Dimension Hints: If a ruler photo isn't possible, provide the dimensions of the area shown in the photo (e.g., "This image shows a 120cm x 120cm section of the wood decor").

Seamless Tiling: For materials that repeat (like fabrics), the images should be seamless / tileable so they can cover large surfaces without visible edges.

Format: High-quality .JPG or .PNG (ideally 1024px or 2048px).

Scale is Key: If the scale is wrong, a heavy fabric weave might look like tiny dots in 3D. Always verify the Real-World Size info before submitting.

Consistency: Once a material is created and optimized, it can be saved in your Rubens Admin and reused for any future products.
