Maybe i'm missing something...
Isn't it possible to export point clouds and camera tracker results?
What if i want to render on external 3D application?
Is it one way only solution?

You can export the camera with an FBX Exporter node. The point cloud itself cannot be exported, but you can use a Replicate3D node to put a bit of geometry at each locator and export that with the same FBX Exporter.

Thanks Bryan!
I was facing it the wrong way looking for some kind of export command in the node popup menu.

YAY!

I think i got a faster way to export the point cloud!
If you select the point cloud node and CTRL+C, then you can paste it as text into a text editor, with all points coordinates!

After that, with a simple text editor macro it's easy to convert the text into a Wavefront OBJ vertex only file and load into a 3D app!



That said, please BM add a direct export feature!

Yes please BM. Please create a point cloud export in the FBXexporter. It would be so useful. Thank you

In the mean time while waiting for native features to arrive from BMD...

There is an "Export Point Cloud" script in the Reactor Package Manager. It does PLY, XYZ ASCII, Maya ASCII, and OpenUSD ASCII export of the currently selected point cloud or Camera3D node in the flow view. There is a thread on the Steakunderwater forum about this script



The Vonk Ultra data nodes in Reactor has a "v3DToFile" node-based point cloud export fuse.

WOW - Reactor is super interesting. Why did I not know about this before? So many great scripts.
Lots to investigate ...
That said .. I still think that point clouds should be offered as part of the FBX export .
Many thanks for sharing reactor.

Honestly, if I had to guess roadmaps for BMD Fusion Studio, I'd predict not a single programmer hour will be put into improving the legacy Fusion 3D system at this point in its lifecycle. All development in 2023 and beyond is likely going to be spent on building out the new OpenUSD based 3D node graph so it rapidly hits feature parity.

If that is the case you'd likely get a USDExporter node that could do point cloud export sooner than later.
