I get this error on exporting. Wanted to adjust the rotation and posotion for later use and reexport.
Unfortunately the mesh has no position attribute.

Python: Traceback (most recent call last):

Impossible to import a gaussian splatting generate with a sh_degree different than 3, for example :
python train.py -s ./dataset/mont_1/ --sh_degree 1
We obtain :
Python: Traceback (most recent call last): File "/home/chupin/.config/blender/3.4/scripts/addons/blender-addon/__init__.py", line 80, in execute features_extra = features_extra.reshape((N, 3, 15)) ValueError: cannot reshape array of size 52317216 into shape (2179884,3,15)

It might come from the default casting of a sh_degree=3 gaussian splatting incompatible with sh_degree!=3

I just wanted to say thanks for releasing this, it's awesome and sooooo needed in Blender. I really hope some coders (I'm not) can help continue the development and contribute this repo, as it is most definitely needed!

Thank you!

can't install as regular addon in 3.6 and 3.5. any suggestion? thanks!! (i'm on windows)

Other Viewer:

For me the the particles in blender are round and not the "splatted" shape they should have. In other viewers the GS file looks correct. Did someone have the same problem?

Importing the GS model is normal, but there is no export button. Does anyone know the reason? Blender4.0

Hello,
Thank you for your work.

I'm on Ubuntu with Blender 4.0.x and I get the following error during import.
It seems that pullrequests can provide a solution even if these errors are not in the discussion of pullrequests.

I can't import ply files, it always gives me this error, on Blender 6.5.1 and MacBookPro M2

how can I solve it?
Grazie

Using Blender 3.4 on macOS. I installed and enabled the plugin.

I can import a splat .ply file just fine and see it in the scene. But exporting it, even if I’ve made no changes, outputs this error instead:

Python: Traceback (most recent call last):
  File “[redacted]/gaussian-splatting-blender-addon-master/__init__.py", line 1075, in execute
    xyz[i] = position_attr.data[i].vector.to_tuple()
AttributeError: 'NoneType' object has no attribute ‘data'

I tried ignoring the NoneType objects:

         for i, _ in enumerate(mesh.vertices):
+            if position_attr is None:
+                continue
             xyz[i] = position_attr.data[i].vector.to_tuple()

That kinda goes around the problem, but that just outputs a big empty files with mostly empty bytes (0x00).

Any idea? How do you export splats?

Not sure why I get this...

importing a splat file called vessel.splat and using Blender 4.0 ??

Appreciate being pointed in the right direction ... (",)

I tried a few splat, converted into Uncompressed PLY using Super-Splat:
https://playcanvas.com/super-splat

Some PLY uncompressed works fine, but a few keeps on failing.

Getting an error when importing PolyCam Gaussian Splatting SPLAT PLY files into Blender using your Addon.

Error line 229

I am Blender 3.3 and I have tested 2.98, which is the same error. I am unable to use the sh script, so I compressed the zip file using the 7z program myself. Use the splat file generated by TriplaneGaussian. I'm not sure if this is the problem, I hope we can provide a release version.

When I tried to import the ply file from the train's point cloud result in gaussian_splatting, I met with this problem:

help

hi,

First thank you for the addon, I was trying it, but after import the gaussian splatting file into blender, only get the points cloud no color or texture information cames! how i can add it the textures to the splatting?

thks

Hi, sorry to leave a question in the bugs area.

Does this implementation in blender allow for splat viewpoint variations? (Not sure what the correct terminology is) basically, will reflections work correctly from different viewpoints in blender? Or are the material shaders just fixed?

Hi, first I want to say thanks for publishing this addon, it looks super useful. I'm trying to import a ply from the polycam gaussian splatting app however I get an error when I do. I'm using blender 3.6.4 on Mac OS.

If you are able to give me any help I'd really appreciate it. I'm not very familiar with blender scripting unfortunately otherwise I'd try to fix this myself.

Thanks for the plug-in ! For some reason I get the Polycam splatt point cloud but no geometry nodes?? I can import fine into Unity etc... HELP !! See screenshot...
