How to Send Blender Files?

If you want to hand over a 3D model or scene created in Blender to someone else, it's basically okay to share the .blend file.

However, there are some cautions regarding Blender files. If you are loading external files like image textures in your created data, if you only send the .blend file, the textures may not display correctly on the recipient's system.

Therefore, it is important to not just send the .blend file, but to bundle the necessary external data before sharing as needed.

This article will detail the basic methods for sending Blender files, how to send them with textures included, and sharing methods when the file size is large.

Main Methods for Sending Blender Files

There are several methods for sending Blender files. It’s convenient to choose based on the distance to the recipient, file size, and how long you want to keep it available.

• Attach it to an email
• Share via cloud storage
• Use a file transfer service
• Send it as a ZIP file

Especially for small .blend files of a few MB, you can send them via email, but projects containing 3D models or high-resolution textures may result in larger file sizes.

In such cases, using a file transfer service to send a download URL to the recipient is a convenient method.

The Easiest Method is Using a File Uploader

If you just want to hand a Blender file to someone, using a file uploader is easy.

For example, UploadF can be used from both PCs and smartphones to upload and share Blender .blend files.

A download URL is generated for the uploaded file, so you can easily send that URL to share the file.

It supports drag & drop, so if you're on a PC, you can upload the Blender file by simply dragging it into the browser.

Additionally, it is free to use and allows multiple files to be uploaded at the same time, making it convenient if you want to share .blend files along with textures.

If you want to share files for a limited time, the ability to set a storage period is also an advantage of file transfer services.

Should I Just Send the Blender .blend File?

This is an important point when sharing Blender files.

In Blender, external data like image textures may be saved separately from the .blend file.

The official Blender manual also explains that external data such as texture images can be "packed" into the .blend file.

This means that, depending on the project, the structure could look like this:

• project.blend
• texture01.png
• texture02.jpg
• texture03.png

If you only send project.blend in this state, the external textures may not be present on the recipient's PC, leading to incorrect display.

If you want the recipient to recreate what you've made exactly in Blender, check how to handle external data before sending.

How to Send Blender Files with Textures Included

If you want to bundle external textures into the .blend file, you can use Blender's "Pack Resources".

From the Blender menu, select the following items.

File → External Data → Pack Resources

According to the official Blender manual, after executing Pack Resources and saving the .blend file, the relevant external resources will be packed into the .blend file.

This allows you to gather supported external data into the .blend file, making it easier to send just a single .blend file.

However, not all external files can be packed. The official Blender manual states that certain large external files like videos cannot be packed into the .blend file.

Therefore, if your project uses videos or special external data, check if you need to send them separately from the .blend file.

Check External Files Before Sending

In Blender, you can manage paths to external files as relative or absolute paths. If you use external data as separate files, changing the location of those files may break the links.

Thus, when handing over a project to someone else, it's a good idea to verify the following:

• Is all necessary data included with just the .blend file?
• Are you not using external textures?
• Are you not using external files like videos?
• Is there no need to send external files?
• Did you confirm the version of Blender the recipient is using?

Especially the issue of "it displays correctly on my PC but not on theirs" could indicate missing external file shares.

How to Send Multiple Blender-Related Files Together

If you need to send external textures or videos along with the .blend file, you can bundle multiple files into a ZIP format.

For example, prepare a folder like the following:

BlenderProject/
├─ project.blend
├─ textures/
│  ├─ texture01.png
│  └─ texture02.jpg
└─ movie/
   └─ background.mp4

After compressing this folder into a ZIP file, you can send it, thus bundling multiple files into one.

On the receiving side, they only need to extract the ZIP file, making it convenient when sharing Blender projects with many files.

However, compressing into a ZIP file does not always mean that the file size will decrease significantly. For data that is already compressed, such as PNG, JPEG, and videos, the size reduction from ZIP compression may be minor.

What if the Blender File is Too Large to Send?

Blender projects can become large not just because of models but also high-resolution textures, HDRIs, and videos.

If you cannot send them via email attachment, using a file uploader makes it easy.

UploadF allows you to upload various files including Blender .blend files. It supports drag & drop on the PC, allowing you to share without complex procedures.

You can also upload multiple files at once, so you can share files like:

• project.blend
• texture01.png
• texture02.png
• reference image.jpg

If "it's a hassle to bundle into a ZIP" or "I want to just send the recipient a download URL," then using a file uploader is convenient.

If You Want to Share Blender Files Safely

When sharing 3D models you've created for work or unpublished works, it's important not to make them accessible to everyone.

For example, if you use a service that allows you to set a password along with the shared URL, you can prevent files from being obtained just by knowing the URL.

UploadF allows you to set a password when uploading files.

By separating who receives the "URL" from who receives the "password," you can share files more cautiously.

If you want to delete any files that are no longer needed after sharing, the individual file deletion function can also be used.

Checklist When Sending Blender Files

By confirming the following before sending, you can reduce issues like the recipient being unable to open the file or textures not displaying.

• □ Saved the .blend file
• □ Checked external files like textures
• □ Sent the necessary external files together
• □ Confirmed if there's a need to use Pack Resources
• □ Checked for external files like videos that cannot be packed
• □ Bundled them into a ZIP file as needed
• □ Confirmed the version of Blender the recipient will use
• □ Deleted unnecessary files after sharing

Can I Send Blender Files from a Smartphone?

It is also possible to send Blender files created on a PC from a smartphone.

For example, after moving the .blend file from the PC to the smartphone, you can upload it to a smartphone-compatible file uploader and send the shared URL from your smartphone.

UploadF can be used from both PC and smartphone, making it a useful method when you want to share Blender files while on the go.

However, if you need to edit the Blender file itself on your smartphone, file sharing and Blender's operational environment are separate issues. Here, it’s best to use it solely for the purpose of "handing the file to someone."

What is Convenient for Sending Blender Files?

When sending Blender files, it is recommended to choose based on file size and whether external data is included.

Method	Suitable Cases
Email Attachment	Sending small .blend files
Cloud Storage	Continuously sharing files
ZIP Files	Bundling .blend and external files
File Uploader	Easy temporary sharing via URL

If you just need to send the .blend file once, using a file uploader is easy.

In particular, if you want to finish with "upload file → copy URL → send to the recipient" , there's no need for detailed settings for sharing in cloud storage.

Conclusion: Be Cautious about External Data When Sending Blender Files

If you only need to send a Blender .blend file, you can easily share it using file uploaders or cloud storage.

However, if you are using external files for textures, just sending the .blend file may lead to incorrect display on the recipient's environment.

In that case, use Blender's File → External Data → Pack Resources to pack external data, or bundle the necessary files into a ZIP file to send them together.

If "I just want to hand over the Blender files" is your priority, using a file uploader like UploadF allows sharing simply by sending the URL of the uploaded file.

It can be used from both PC and smartphone, and supports drag & drop, making it useful for temporary file transfers of Blender files.
