Submitting Your StemCell 3D Model for Conversion


The StemCell submission process has been migrated to the One Page Publisher on TurboSquid to provide a smoother experience where everything is done in one place. The model then goes through our updated precheck and validation processes, which are detailed below.

Creating a StemCell Job

  1. Navigate to the One Page Publisher by going to My Products in your account dropdown.
  2. Select Create New Product.
    Create New Product button in TurboSquid One Page Publisher
  3. Upload your StemCell file (3ds Max or Blender) and be sure to designate it as the Native File.

  4. Upload the required preview images.

  5. Be sure to select “Submit model for StemCell certification”. This is what tells the system to submit your model to the StemCell-specific pipeline.

Job Processing

Once your job has been submitted, it goes through a series of stages to reach the published state. The stages are as follows:

  • Upload: The file needs to be uploaded as an initial submission or for any required changes.
  • Precheck: The file runs through technical checks for StemCell specification compliance. If the file passes, it proceeds to the next stage. Otherwise, it returns to Upload for any required fixes.
  • Conversion: The file is then converted into the various DCC and exchange formats.
  • Verification: During this stage, the artist must review the converted model renders. This is a good time to spot any surface and material issues that need to be fixed. If the renders look good, the artist may pass them to the next stage. Otherwise, they can reupload with any changes.
  • Approval: At this stage, our team does a final manual review of the converted models and either passes them to the next step or sends them back with any required changes.
  • Publish stage: Once approved, the model goes through the publish process. This used to be done manually, but we have improved it to be done automatically.

StemCell Submission User Experience

Below are some examples of things you’ll see while navigating through the submission process.


Reviewing Errors and Precheck Feedback

If the file is sent back to Upload for required changes, you will see it in the StemCell submission area as an error. You can click this to open a window that describes the fixes needed:

StemCell Error status with See Details control

You will see a section that has all of the passed and failed tests. You can expand these to see the details of each test category and what requires fixes:

The sections highlighted in red are errors that you will need to fix manually, while those highlighted in blue are warnings and automated changes done as cleanup for your file that don’t require any further action:

Verifying Converted Formats

If the file passes and converts with all the formats, it will proceed to the Verification stage, where you have the ability to review the end result:

You have the option to exclude some formats if you are not happy with the results but like the other renders or formats. Please note that in some cases, if the issues are present in the native file, we may still send the files back for fixes even if some renders are excluded.

Understanding StemCell Statuses

There are three main statuses you will see in the StemCell status area:

  • Error: The model fails for any reason. Click on the hyperlink to open the error details window.
  • Queued: The job is processing either for Precheck or is converting to the other formats.
  • Action Required: The job needs to be verified by the artist. If it has already been verified, it is in our queue for manual Technical Artist approval.

Viewing Technical Artist Feedback

If your model was sent back by a Technical Artist, or we need to pass on any information about the model, you will see this information in the Discussion and History section:
