Reading time of this article:0 minuteUpdated 2025-06-11

For product models that want to be displayed on the Public Library , the name should accurately describe the product , and the category and preview image must also match with the actual product.

For Users

All enterprise users

Product Information

1. Name

(1) You can choose from the following keywords:

Brand, Style, Color, Material, Space, Type(MUST BE INCLUDED).

Don't change the order of this keywords.

(2) Not allowed keywords:

Pure numbers, special symbols(\ / _ > < * % ^ ! ~), personal names, place names, company names, and contact information.

Reference: Castle Rock Bar Table

2. Model Category: Match with the actual product category

Reference：

3. Angle of Preview : The preview model is set on frontal view

So please adjust the model to a right orientation on the modeling software before uploading.

Reference:

Model Quality

Model displayed on the public library must be modeled correctly according to the Coohom modeling standards with clear material textures and correct structures.

1. Model Material

(1) White model is not allowed:

Models without any material are not allowed.

Incorrect example:

(2) Black surface is not allowed:

Material turn black due to material loss, normal reversal or UVW error.

Incorrect example:

(3) Texture error is not allowed :

Models with broken texture or textures that do not match the actual effect.

Incorrect example:

(4) Using reasonable materials:

Materials like leather or fabric should have clear textures , especially for black color material.

Effect reference:

(5) Unreasonable color matching is not allowed:

Color matching should be good looking, not too bright or appear as material loss colors, like bright red, green or purple.

Incorrect example:

(6) Texture size:

It is recommended that textures file size used on the model within 1-10 M.

(7) Image format :

The texture files used on the model should be .jpg, .png, or .jpeg format, with the RGB color mode.

2. The model structure must be displayed clearly and accurately

(1) Interpenetration, overlapped faces, and broken surfaces are not allowed:

Incorrect example:

(2) Low precision models are not allowed:

Incorrect example:

(3) Non centered models are not allowed:

There are unless objects around, causing the model not to be centered.

Incorrect example:

(4) Single-sided model is not allowed:

Single-side faces can cause abnormal rendering effects, like fish eye distortion.

Incorrect example: (the thickness is 0 )

3. The model's appearance should be reasonable and following current trends and aesthetics

(1) Trends:

Materials such as stone, metal, acrylic, etc., are more in line with current trends. Generally, Only models created within the last 3 years will be published to the public library.

(2) Proportion Coordination:

Decorations should match the main furniture, and individual furniture within furniture sets should also maintain proportional coordination.

(3) High Quality Model:

The model has a reasonable structure with seamless textures.

(4) Accurate Dimensions:

The model should adhere to standard real-world sizes. The model’s dimensions should not exceed 30 meters (length, width, and height all should not exceed 30 meters). Special-sized models will be considered case-by-case.

4. Set the Gamma/LUT value to 2.2, meaning the model preview background should be pure white

(1) Opening the 3ds max source file and setting the Gamma value to 2.2.

Reference:

(2) VRay material reflection and refraction subdivision value set between 8-16.

Model Combination

1. A single part of a model is not allowed

(1) For example, the left/right arm of a sofa or the corner piece.

Incorrect example:

(2) The accessories of cabinet/wardrobe models, like drawer frames, built-in baskets, back panels, are custom accessories for customized cabinets. Don’t publish them to the Design Tool public library. They can be uploaded to the Advanced Tool Custom model library.

Incorrect example:

2. Model combinations can be published as appropriate

(1) Inseparable combined furniture (like modular wardrobes) and furniture with accessories (like wardrobe with clothes) can be uploaded as a whole.

Reference:

(2) Furniture with a background wall needs to be separated. While TV cabinet set with necessary background can be uploaded as a whole.

Reference:

Incorrect example:

(3) Multiple individual models need to be separated and uploaded individually.

(4) Multiple ceiling models for different spaces need to be separated and uploaded individually.

(5) The furniture sets:

5.1. The furniture sets model combination should be set at front view, and set as “Show in tool”.

5.2. Only the following categories of furniture sets can be published: sofa combinations, TV cabinet combinations, dining table combinations, bedroom combinations, vanity table combinations, and desk combinations.

(6) Requirements for publishing the furniture collections:

Models of the same series with different colors, directions, and materials can be added to a collection and be published together.
