Convert Your 3D Mesh/Model PMX Files to USD

Our free and fast tool will convert your 3D PMX (MikuMikuDance 3D Model) model files to a standard USD (Universal Scene Description) file that can then be edited further in most popular 3D editing packages or 3D printed without any further processing. Our conversion tool can also batch convert multiple PMX files; up to 200 files at a time can be converted.

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

Description

The PMX format is a 3D graphics format associated with MikuMikuDance program that allows users to create animated character renders that have been used in anime television series.

Contained within a PMX file are the basic 3D character model, textures, poses and animations.

Description

The USD format is a relatively new 3D file format developed by Pixar in 2016. The format is open source and has the support of major players in the space, such as Apple, Adobe, and more.

USD files encapsulate a full 3D scene along with any associated 3D models, animations, and visual effects into a single compact binary file. USD files can be opened with most popular 3D editing software, such as Blender.

How does it work?

Converting from the PMX file format to USD 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 PMX file to a valid USD 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source PMX File

In its simplest form, an PMX file is a binary data 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, and normals, as this is the only data that can be accurately converted into the final USD file.

The PMX file can contain other data, such as material definitions and textures, that describe how a particular set of 3D geometry should be rendered. As we are creating an USD file, which does not support materials and textures, we will be ignoring this data if it is present in the PMX file.

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

Step 2: Process File Data

With the PMX 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 USD format.

Step 3: Saving to the USD 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 USD format.

Frequently Asked Questions

I have several PMX files; can I batch convert my PMX to USD?

Yes! Our PMX tool supports full batch conversions. You can upload up to 200 PMX files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the USD files individually or download them all in a single ZIP file.

How can I convert my PMX file to USD?

First click the "Upload..." button, and select your PMX file to upload. You can also drag and drop your file onto the tool. Once your file is selected, you can set any configuration options. When the PMX to USD conversion has completed, you can download your USD file straight away.

How long does it take to convert my PMX to USD?

We aim to process all PMX to USD 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 PMX to USD 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 PMX to USD on ImageToStl.com?

Yes, of course! We do not store the PMX file you submit to us. The resulting USD file, once created, is stored for 4 hours after upload; after this time it is deleted, and the short-term download link will stop working. You can create a long-term download Url with most tools that will ensure the file is retained for 24 hours, allowing you to download the file when convenient. Our tools also come with a Delete button, allowing you to delete the file immediately.

Do I need a high-spec. computer to use the PMX to USD converter?

No. All our conversion tools process your PMX 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 USD file quickly.

Can I convert my PMX to USD on Windows, Linux, Android, iOS or Mac OS?

Yes! Our PMX to USD 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 PMX conversion tool please consider white-listing our website. When an Ad Blocker is enabled there are some conversion limits and some settings may not be available when using our tools. Processing/conversion and download times will also be longer.

Can I get support with converting my PMX to USD?

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