Gaussian Splatting .PLY files import problem - nothing appears in the scene

Get Help
1

As the title suggests, I’ve tried importing several different .ply files. However, when I drag them into the scene, all I get is an object icon, and nothing actually appears. The object has zero dimensions.

Why is this happening? I’m working on a large project where I need to import the surrounding environment using Gaussian Splatting. How can I get this to work?

Hi @wojciechmarekbudzyn

Can you show us the process via a video recording? Or perhaps you can send us the .ply file for us to test.

To clarify,

  • .ply files can be imported into your MySpace page to create an XR Tour.

  • It can also be directly imported into D5. For my test, I downloaded the .ply file from an XR Tour, and placing it in D5 shows the model.

Here’s the screen recording of the process. These .ply files come from Sketchfab, you can try with any .ply file from this website.

Hi @wojciechmarekbudzyn

Got it but I’m not very familiar with Sketchfab and whether it provides a search filter that allows users to view all available .ply files, rather than having to search for individual models that use the .ply format.

  • If you’re unable to provide the files used in your video, please send us a Sketchfab link to a downloadable .ply file that demonstrates the same issue. This will allow us to obtain the file directly and proceed with testing as soon as possible.

Hi,
There is the .ply file I used in the video:

I’m starting work on a project where I’ll be creating my own Gaussian Splatting files, and I’d like to use them in D5 Render, so it would be great if this functionality could be fixed and made to work properly.

Hi @wojciechmarekbudzyn

Thanks for this. I just confirmed with our team regarding this issue.

D5 Render does not support the .ply format as a direct model import. The supported formats for direct import are:

  • SketchUp (.skp)
  • Autodesk FBX (.fbx)
  • D5 model (.d5a)
  • Rhino (.3dm)
  • Alembic animated file (.abc)

But .ply is supported in a different context: the XR Tour module.

  • You can import .ply/.sog files into D5 XR Tour when creating an XR project (via Create > XR Tour > Upload 3DGS File),

Note: This is for 3D Gaussian Splatting (3DGS) point-cloud data, not for importing standard polygonal geometry into the main D5 Render scene.

If you need to bring .ply geometry into D5 Render, the recommended workaround is to convert the .ply file to .fbx or .3dm using your modeling software (e.g., Rhino, Blender, 3ds Max) first, then import the converted file.
