Worries
3If the 3D model is not displayed in the thumbnail or preview of the 3D file, it is difficult to confirm what kind of 3D model it is. . .
I want to check the 3D model without opening the viewer for the contents of the 3D file!
If you do not have any settings in Windows 10 Explorer or Mac Finder
Some 3D files can be viewed with thumbnails, but many 3D files cannot be viewed with thumbnails or previews.
To solve this problem, I found several ways to display 3D models in thumbnails and previews without opening the 3D file.
It runs commands to display 3D files. This can be achieved by installing a plugin, etc.
- Otherwise, the only way is to open a 3D viewer or use 3D modeling software.
- I have verified and confirmed that some 3D files are able to display 3D models and some are not. (Currently 2020/04/03)
- This time, I will show you how to display a 3D model as a thumbnail or preview without opening the 3D file.
- The first half covers the Windows environment, and the second half covers the Mac environment. That’s because the methods are very different.
Difference in language
First, this article defines the meaning of each word as follows.
- Thumbnail: An image displayed on Explorer.
- Preview: The ability to simulate and check on-screen the results of a 3D model’s output.
- Viewer: Software for viewing 3D models.
- File manager: Software that manages files.
List of various ways to check 3D models
We will explain the recommended confirmation method for each 3D file extension.

.blend is a standard file for Blender.
If Blender is installed, you can display thumbnails by running the following command.
- Run Command Prompt as administrator. Navigate to the location of Blender.exe.
blender -R- File extension registered for all users. If it appears, it is a success.
1. C:\WINDOWS\system32>cd ../
2. C:\Windows>cd ../
3. C:\>cd "C:\Program Files\Blender Foundation\Blender 2.81"
4. C:\Program Files\Blender Foundation\Blender 2.81>blender -R

The thumbnail of the 3D model on Explorer is displayed in blue, but it’s better than not knowing what it looks like.
.max
.max is a standard file for 3dsMax. You can enable it if 3ds Max is already installed.

You can also enable thumbnail display by executing this command.
1. Run Command Prompt as administrator and enter the following command:
C:\WINDOWS\system32>regsvr32 "C:\Program Files\Autodesk\3ds Max 2020\MaxThumbnailShellExt.dll"2. If the message “DllRegisterServer for MaxThumbnailShellExt.dll succeeded.” appears, it is a success.
Failure example
Loading module “X:\3dsmax root folder\MaxThumbnailShellExt.dll” failed to load. Verify that the binary is stored in the specified path, or check for problems with the binary or dependent .DLL files.
This error message means that the path to MaxThumbnailShellExt.dll is incorrect.
Please specify the correct path for MaxThumbnailShellExt.dll.

.3ds
- .3ds can be viewed with a file manager called 3D Photo Browser.
- This is not software that displays thumbnails on Explorer.

It was nice to be able to display thumbnails of 3D models using 3D Photo Browser, but I personally found it difficult to use.
.fbx
I haven’t found a way to display thumbnails of fbx in Explorer, so I use FBX Review.
It is loaded in Explorer, but cannot be displayed.
.skp
I haven’t found a way to display thumbnails, so I’ll use SketchUp Viewer.

Things I tried to display thumbnails of 3D files
Other ways to display 3D files include using viewers and file managers other than those listed above.
I have only tried these out for experience.
- GLC player
- A 3D viewer that supports COLLADA (.dae), .3dsxml, .obj, 3ds, .stl, .off, and .coff formats.
- GLC_Player — Home
- DDS Thumbnail Viewer
- NVIDIA’s thumbnail viewer. You can view .dds files in Windows Explorer’s thumbnail view.
- DDS Thumbnail Viewer|NVIDIA
- Meshlab
- A viewer that supports 3D files such as 3D scans and 3D prints.
- MeshLab
I tried using the following software, but I gave up because I didn’t know if it would display 3D thumbnails. – SageThumbs
- This is software that can display thumbnails of many files.
- I always use SageThumbs to display Sage.psd, .ai, etc., but adding the 3D file item didn’t make any difference.
- Software that can enhance and expand the image preview function of “SageThumbs” Explorer – Window Forest
- Directory Opus Download Directory Opus
- XnView “XnView” Explorer-type image viewer – Window Forest
- These two software are explorer-type image viewers and file managers.
Mac operating environment & applications used
From here, we will show you the QuickLook plug-ins and viewers required by extension to thumbnail 3D models on Mac. – .dae .obj .stl are 3D files that can be previewed by default on Mac.
- .blend .gltf .vrm .pmx can be previewed with the QuickLook plugin
macOS Mojave QuickLook plugin – .blend→ vicro/BlenderQuickLook v0.1
- .glTF
- → toshiks / Quicklook Plugin v1.1
- → magicien / GLTFQuickLook
- .vrm → magicien/VRMQuickLook
- .pmx → magicien / MikuMikuDanceQuickLook
Viewer – .fbx, .3ds→ FBX Review
- .skp→ SketchUp Viewer
- .glTF→ donmccurdy / glTF Viewer
- .vrm→ yukimochi / VRM viewer
- .max→ AutoDesk Viewer
.qlgenerator(QuickLook plugin)
The official name is Quick Look Preview Generator. or Apple Quicklook Plug-in. It’s called. By having a .qlgenerator file, you can display thumbnails in the Finder preview.
How to install .qlgenerator
I will explain using vicro/BlenderQuickLook v0.1 as an example.
1. Download qlgenerator.
2. Open the .dmg file and there will be a zip folder.
3. Extract the zip folder and copy ○○.qlgenerator.
4. Paste in Library > QuickLook.
5. Reset QuickLook in the terminal.
qlmanage -r
qlmanage resetting quicklookd
If this message is returned, it is successful. Now qlgenerator will be reflected. Due to incompatibility between the macOS version and qlgenerator, a shader error may occur where the 3D model preview is displayed in magenta (pink).

.fbx, .3ds
In my research, I couldn’t find a way to display thumbnails of FBX or 3DS. Therefore, I will use Autodesk FBX Review, which you may be familiar with.
Memo: Where is fbx Quick Look..? What I tried to preview fbx
fbx is the file I use most among 3D files. Here is what I tried through trial and error to display fbx as thumbnails. I found **Clay Viewer** while searching for software that can display fbx.
[Releases · pissang/clay-viewer · GitHub](https://github.com/pissang/clay-viewer/releases/)
.fbx animations are smoother than FBX Viewer.
.dae
It looks different depending on the software. Next, I found and used various online 3D viewers such as **FBX, glTF, and GLB 3D Viewer**.
[FBX, glTF, GLB 3D Viewer – Chrome Web Store](https://chrome.google.com/webstore/detail/fbx-gltf-glb-3d-viewer/ddmladejiediokofnpdflciecailajkp)
I personally do not recommend **FBX, glTF, GLB 3D Viewer** due to their capacity limitations.
– The ability to preview fbx with thumbnails is not currently available (2019/12/1).
– **I have no choice but to check the model by dragging and dropping it onto the FBX Viewer. **

Summary
The following shows whether thumbnails are displayed in the Windows Explorer preview. Thumbnail display compatibility table (Windows)
| Extension | Support | Explanation |

| .3mf .obj | 〇 | File size small. Visible by default. |
| .stl .blend .max .3ds .dae | ×→〇 | Not supported by default → Can be displayed by customizing |
| .fbx .gltf | × | It is loaded but cannot be displayed. |
| .obj | × | If the file size is large, the loading will end midway. |
- Explorer previews do not seem to display thumbnails unless the file size is small.
- The thumbnails that can be displayed vary depending on your PC and file size. (Example: .blend .max)
Mac Mac also shows support for thumbnail display on the Finder preview. Thumbnail display compatibility table (Mac)

| .blend .gltf .vrm .pmx | ×→〇 | Can be displayed in preview with QuickLook plugin |
Lastly
We introduced a method to display 3D files in thumbnails and previews without having to open them each time. I was able to display thumbnails successfully using various methods, so I would like to thank the creators of the viewer and quicklook plugins.
