Importing PLY background in Ax - Forum

Importing PLY background in Aximmetry 2026.2.0 with Volinga 0.9.0 plugin.

Dear Aximmetry Admins,

We have a single Workstation setup with a AMD Ryzen 9 3950X 16-Core Processor, GIGABYTE X570 AORUS XTREME Motherboard, MSI RTX 5090 graphics card, 64 GB Ram and one Decklink 8K Card running Windows 11 Pro 25H2 and Aximmetry 2026.2.0. with Volinga plugin 0.9.0 license.

At AX_Scene_Editor_2026.2.0 we have successfully cooked the PLY background project.

After importing the project in AXIMMETRY BROADCAST & FILM 2026.2.0 We can see in the upper third of the screen a blur that looks like a cloud, which we cannot remove in order to see our background clearly.

Also, this is the image (Screenshot3) from the preview of our second camera, which is positioned approximately 30 to 40 degrees to the left of our main camera.

Also, if we disconnect the Control Data and B Texture pins in the Flow editor, we can see the background clearly, but without having our cameras keyed.

And a second question: if we manage to fix this issue and view it properly, the PLY background will it be able to move correctly in relation to the movements of our three cameras?

Thank you for your attention.

The blur you’re seeing is from the Gaussian splat itself. Your camera is placed outside of the intended camera placement coverage in the scene or placed behind an object in the scene. This is a natural side effect of Gaussian splats. Just move the scene offset in Aximmetry so that the camera is placed fully inside the actual scene. What camera tracking system are you using? Does it have absolute world positioning and how do you set your “world zero”? If you’re camera tracking system is properly set up and if the scene is done at accurate real world scale, if course you will be able to move it in relation to the camera.

Our tracking system is a VIVE Mars CamTrack. It appears that the PLY is being divided into two separate sections. The first section can be moved in /Inputs Editor /Input 1 /ORIGIN 1 /Delta Cam Transf, while the second section can be moved in /Flow Editor /Cooked project /Cam Transform.

Additionally, at the end of the video link in YouTube, we can observe the behavior of the PLY background when a keyed camera is also included.

If I understand correctly, shouldn’t the PLY background be treated as a single continuous piece of geometry rather than as two separate parts?

When we load the background as an FBX file, we do not have any such issue. We see it as a single object.

Thank you for your patience.

Hello AKTISAVteam,
I've noticed that your Aximmetry setup is using a TrackedCam compound paired with a Virtual+Tracked camera in the Unreal project.You should always aim to use the same camera compound and UE camera to avoid any possible issues.In your case, you should use any of the [Common_Studio]:Camera\MixedCam_Unreal compounds if both virtual and tracked cameras will be used in your project.If you will only use tracked cameras, we suggest changing the UE camera to a Green camera (tracked) instead.
We managed to reproduce this issue, but only with an incorrect camera pairing.
The reason behind having a double render of the Splat is the missing connection to the Virtual Camera inputs. Aximmetry controls if the virtual or tracked camera render should be active, without this connection the information is lost and you get a double render.
