Rules

1. Archive

We accept archives in the following formats: rar, zip, 7z up to 200 MB.

The archive should include:

3dsMAX File
Textures ( all textures must be saved in one folder only )
Export File – FBX or OBJ ( if some materials cannot be exported )
Materials library ( optional )
The “MAXFILES.TXT” file, if possible, should not be deleted from the archive
Do not remove mtl., File, if you are exporting into OBJ. In order to avoid unwanted distribution of models on the internet do not keep extra previews in the Archive.

2. 3dsMAX version

We don't accept models saved in 3ds Max versions of 2023 and later ones.

To increase number of potential buyers of your models we recommend to save 3ds Max files in the lowest possible versions. Many users still use earlier versions of the program.

For example, if your 3ds Max is version 2023, we recommend to save the file in version 2020.

3. In which Software all models are checking

All Export Files are checking in MAX 2014.

4. Third-party plugins are not accepted

Even Free Plugins ( like MultiTexture, Color Correct, Color Map, Complex Fresnel, Bercon Maps, Siger Noise, Siger Scratches, Thin Film etc. ), are not accepted, if you want to get LT or PRO for your models For example, Color Correction – standard map in 3ds MAX. Color Correct - third-party plugin, which cannot be accepted. Complex Fresnel can be changed to standard MAX Falloff map with same Curve settings in Output Slot

5. Preparing 3ds max files and export files before uploading models

Before exporting un-group all objects, convert them to Poly, Collapse all geometry, and assign Reset X-Form. Make sure that the Triangle option in the export settings is not active. Then check your Export File. Don't forget to check Normals. Model should be in Zero coordinates and not rotated along X, Y, or Z axis Units – millimeters Symbols ( ‘, “, * etc. ) are not accepted. Alphabet letters ( English ) are only accepted. If you choose both Render Engines – Vray and Corona and choose FBX as Export file, then both files ( Vray and Corona ), must be in FBX exported. Models made in student versions of MAX are not accepted.

6. VRay and Corona Render Engines

If your Vray version is higher than SP1, you should write in Description: “Who works with V-Ray version lower than 3.1, pay attention to materials section BRDF (Microfaset GTR (GGX)), if your version is older than 3.1 - this section will be empty, and you have to choose: Blinn, Ward or Phong, d dependence on material “.

If your Corona version higher than 1.4, you should write in Description: For Corona render, it is recommended to install a version of at least 1.5, since the glossiness of materials is configured considering PBR. Do not use scripts for converting from Corona to Vray. There are some Maps ( like Corona BitMap ), which cannot be converted with automatic Script and it will be some Missing textures, like Corona BitMaps, which VRay cannot render. Convert all materials manual.

7. Sets of many objects

Sets of many objects (flowers, vases, lamps and furniture objects and etc.) at the same scene and previews are not accepted. Sets of models from different categories are not accepted. To much of objects on preview looks poorly on a common page, full of small previews. Preview is indistinct. It's doesn't match 3dsky rules. To much objects in the scene makes negative effect on the overall competition. We recommend you divide your scene into two or more uploads (in one scene should be no more than 6-object) and make new preview as well. Set contains models from different categories in one scene and preview are not anymore accepted. We recommend you follow this table, for better understanding, what kind of models can be combined in one set.

Sets uploaded into database before this rule was accepted, will remain in the database if the author of the model does not want to split sets and re-upload. Services, servings, wardrobes, libraries (books), pillows, carpets can be loaded as before. Moldings, plinths etc., not more than 10.

We do not accept different types of lamps and furniture in one set.

8. File names, Folders names, Textures names – everything must be in English

Paths to textures in Material Editor must be in English. They must be cleaned in Material editor slot. Here is the instruction, how to clean all paths:

Paths must be clean. Only textures names must be there, but nothing more and don't forget to re-save the export file. Textures names are 1, 2, etc., (ordinal numbers) are not accepted.

9. Preview

ALL Previews should be square form - minimal size 640x640 px. Preview should be maximum informative, no chromatic aberrations, no frames, no extra shadows, no vignette, no dark corners, no bloom or depth of field (DOF), no over exposure on some of corners, no noise, NO logos, no pattern on background. Model must be placed in the center of preview. Background color must be white, black, or grey - depends on model color Blue, pink, yellow, green backgrounds, gradient, horizon, even if it's HDRI map or light reflection are not accepted. Background color must be white, black, or grey - depends on model color Do not use HDRI maps with active blue, green or yellow color, because it will affect the background. On preview and in the scene should be only the model. No lights, no cameras, no other geometry.

Be sure to add a grid image on the latest preview. Exceptions: materials, textures and scripts.

10. Inverted Normals and correct mesh

The correct mesh is mesh, contains quad or triangle polygons only.

Without coplanarity, discontinuities and inverted normals.

11. AI-Generated Model Requirements

Transparency
The “Created with AI” checkbox is required if AI-generated elements are a significant part of the model and affect its unique appearance, purpose, or category.

If AI is used only for minor elements, the removal of which does not affect the appearance, functionality, or category of the model, checking the checkbox is not required. In this case, you may optionally indicate in the description that certain details were generated with AI.

Quality First
The model must be visually accurate and technically suitable for use. Raw AI output must be cleaned, organized, and correctly scaled before upload.

Consistent Formats
Accepted formats: .max, .fbx, .obj. Files must have clear naming and a logical folder structure.

Added Value
AI-based models should provide a solid, usable foundation — not an unfinished mass of shapes. Each model should save the user time by offering a ready, editable base.

No Artifacts
Before uploading, check the model for geometry errors, damaged UVs, overlapping polygons, or other technical defects.

Human Refinement
Every model must undergo final manual review and adjustment to ensure a level of quality beyond raw AI generation.

12. Model status and sending the model for revision

The decision about the model’s status depends on moderator If the model has not passed moderation, you will receive a Privat Message with recomendations. The moderator will not take any part in correcting these errors. If you do not agree with the status of the model, write to moderators to specify the points of the evaluation criteria for which the model did not receive one or another status. Moderator indicates failed criteria

13. Model's errors in the database

If you find a model with some errors, notify moderators in a personal message (see above)

Tags creation

Adding tags according to our recommendations increases the chances of your model appearing in search results and therefore positively affects sales.

Recommendations:

Use nouns only
Try to specify the tag in singular form*
Avoid repeating category names. For example, in the "Chairs" category, you don't need to add "chair" as a tag**
Tags are filled in only in english

* You can use a tag in the plural if there is more than one of these items in the 3D model. For example, if your model contains several books, you can use "books" as a tag

** In addition to the divided sections – "Barbecue and grill", "Sideboard and Chest of drawer", "Toilet and Bidet", "Wardrobe and Display cabinets"

Relevance of the model

The relevance (demand) of the model.

Not everyone understands this point correctly. Relevance is not the absence of a thing in the database, but its usefulness for Architectural Visualizations. For example, the channel model is irrelevant, or relevant only for loft-style interiors. NoName (without article and manufacturer) models are also have very low relevance.

What is now in demand – you can check by visiting the Top of sales

Headline of 3D models on main page

The main page is the face of the site, that's why relevant, high-quality, interesting models are uploading into headline.

Models on main the page are selected by moderators

By default, the model is fixed on Showcase for the whole day.

What you can't do

The following actions with models are strictly prohibited:

Asking others to send you PRO models – users caught making this request will receive a warning. A second request will result in a ban.
Responding to requests for PRO models – anyone who replies to such a request and sends PRO models will be banned immediately.
Leaking the model database – any action that could pass models on to third parties is forbidden. This includes downloading models “just in case,” creating your own personal library, or any other form of redistribution. Users will receive a warning for this. A repeat offense will result in a ban.

Additional Penalties

The following violations fall under extra measures:

Stealing geometry — copying or making unauthorized changes to someone else’s model and publishing it as your own.
Repeatedly ignoring moderators — this applies starting from the third warning for the same violation, when a moderator has already given clear instructions that the author ignored.

Punishments:

For a repeat offense, the author receives an official warning.

If the violation continues after three or more specific instructions from a moderator, the strongest measure is applied: all models in the author’s profile will be temporarily hidden for 3 to 7 days.

Important notes:

During the hiding period, moderators may check and further moderate the content. If the author voluntarily and fully fixes the violation, the models can be restored earlier by decision of the moderators.

The author may request a review of the punishment through support. We will carefully review the case and reply.

Why these rules were introduced:

To prevent repeated violations
To protect authors’ rights
To maintain quality standards on the platform

These additional measures are used rarely and only in serious cases.

Polygon Expert

Periodically, Moderators and Admins choose the best model from 3dsky base

That model receives the status of “Polygon Expert” and is placed into special block in the 3D Models section.

The Author of that 3D model receives a medal of Polygon Expert:
