Convert Your 3D Mesh/Model FBX Files to X

Our free and fast tool will convert most 3D mesh or FBX (Autodesk Filmbox) model files to a standard X (Direct X File) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple FBX files; up to 25 files at a time can be converted.

To convert your FBX file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a X file and will be ready for download shortly afterwards. For more information about the FBX to X conversion process, see the conversion information section below.

Description

The FBX format by AutoDesk was originally developed by Kaydara in the 1990s as a means to store 2D or 3D content with motion data. It has evolved over the years to become a widely used format by 3D modeling applications such as Blender, 3D Studio Max, and others due to its 3D animation capabilities.

The format is used to contain 3D models, which include vertices, faces, and other 3D geometry along with animation data. The format is proprietary; however, there is a publicly available API to use for development purposes. The file contents can be either text or binary, and work has been carried out by the Blender Foundation to document the format.

FBX Notes

If your FBX file contains texture files and other texture-related data, these will be included in the conversion process.

Description

The X 3D file format extension was introduced by Microsoft with the launch of Version 2 of their 3D graphics API, Direct X, back in 2002. The format has evolved over the years; however, in 2014, the X file format was deprecated in favor of newer, more capable formats such as FBX.

The format is a simple text-based file capable of storing 3D mesh information such as vertices, faces, normals, and material information. In addition to basic 3D information, the format can also store animations with the X file format, which is primarily used in the development of games.

X Notes

X files support material and color information. If your uploaded model contains color information, our tool will attempt to save this in the X file at the end of the conversion process. Texture information is not supported at this time.

Supported Features

  • Mesh geometry
  • Material colors
  • Textures

Unsupported Features

  • Animations

How does it work?

Converting from the FBX file format to X can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your FBX file to a valid X 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source FBX File

In its simplest form, an FBX file can be either a plain text or binary file containing 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.

When our tool reads this 3D data, all we are interested in are the vertices, faces, normals, materials, and textures, as this is the only data that can be accurately converted into the final X file.

The FBX file can contain data such as material definitions and textures that describe how a particular set of 3D geometry should be rendered. As we are creating an X file, which supports both materials and textures, our tool will attempt to load any materials and textures present in the FBX file.

For more information regarding the FBX file format, please see this great article that goes into a lot of detail explaining the FBX format.

Step 2: Process File Data

With the FBX file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the X format.

Step 3: Saving to the X Format

With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the X format.

Along with the completed X file, any textures that were present in the original FBX file will be saved in either PNG or JPG format, depending on the original image format. If the original format was neither of these, for example, if your model contained a texture in the TGA format, it will be converted to a PNG.

Frequently Asked Questions

What version of FBX file is supported?

Our tool can read binary FBX versions 7.0 and above and text formatted FBX files version 6.4 and above. Please ensure your FBX version meets these requirements before uploading.

How long does it take to convert my FBX to X?

We aim to process all FBX to X conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the FBX to X conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.

Is it safe to convert my FBX to X on ImageToStl.com?

Yes, of course! We do not store the FBX file you submit to us. The resulting X file, once created is deleted 15 minutes after upload and the download link will expire after this time.

Do I need a high-spec. computer to use the FBX to X converter?

No. All our conversion tools process your FBX file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted X file quickly.

Can I convert my FBX to X on Windows, Linux, Android, iOS or Mac OS?

Yes! Our FBX to X tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our FBX conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

Can I get support with converting my FBX to X?

Yes. When you have converted your FBX to X, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
