Hello,
I tried to import ply Gaussian Splat file, but I get an error
"ply properties header format invalid, pls check it first"

The Gaussian Splat file was generated with Nerfstudio, then converted into PLY through SuperPlat.

I also tried to import PLY to Blender (worked) and re export to another PLY, but it still gets an error in XV3DGS plugin.

Unreal version 5.3.2
XV3DGS plugin 1.0
Windows 11

Thanks a lot for your help.

Is there a way to get the source code?
Unreal displays the .cpp files but they can not be opened.

My scene becomes extremely laggy or crashes outright.I don't know what happened.

Describe the bug
When attempting to load the .ply file into the scene (using the "load GS ply model" button), the UE session immediately crashes. The ply file came from the "https://playcanvas.com/super-splat" web app. The file is relatively light, at just 44.7mb (uncompressed).

To Reproduce
Steps to reproduce the behavior:

1. Go to "https://playcanvas.com/super-splat"
2. Drag and drop a .ply file into the browser window
3. When the scene loads, use the "brush" or "rect" selection tool to select a few dozen particles in the scene and press delete
4. Scroll down the tool panel to "export" and click the "ply file" button, and save to desktop.
5. Load the exported .ply file into UE using the XV3dGS plugin
6. Crash occurs
7. Reload scene, observe the content browser. new empty blueprint folder exists for the asset (suggesting the crash occurred during blueprint creation)

Expected behavior
Unreal should load the ply and create the new GS asset without crashing

Desktop (please complete the following information):

• OS: win10
• Browser: chrome
• UE Version: 5.3.2

You guys plugins are so good I am happy.

Please make it easy to migrate to Fortnite using the Niagara System.

For example, the following link.

https://akiya-research-institute.github.io/3dGaussiansPlugin-Manual/ja/how-to-uefn/

However, even with the linked method, it is still a hassle and we would like to have an easier and better looking feature.

I will gladly test that feature when it is added.

Hello Xverse,

I've been using XV3DGS-UEPlugin for a while now and I'm really impressed with its capabilities.

However, I've encountered a limitation regarding the inability to adjust the training iteration steps. Currently, the plugin runs for a fixed number of iterations, but for my use case, I need the flexibility to alter this based on different datasets and project requirements.

• (The default number of steps for training is 12300)

Having the option to customize the number of training iterations would greatly enhance the plugin's utility, allowing users like myself to tailor the training process more closely to our specific needs.

Thank you for considering this request. I'm looking forward to any updates on this and am happy to provide more information if needed.

Best regards!

Greetings!
Im on unreal engine 5.4 and when i crop a BPGaussianActor created with importer in the editor preview everything is fine and also cropping the points creates a niagara effect cropped correctly, but when i launch it in game the crop position is moved and i cannot find a way to crop the selected area...

To Reproduce
Steps to reproduce the behavior:

1. Latest Plugin release for ue 5.4
2. Imported/trained correctly aBPGaussianActor from an mp4
3. Cropped and everything visualized fine in the editor preview and in the new cropped niagara asset created pushing on "Crop New Points In this Box" button from Clip Volume Component Box
4. Launching the game in editor the crop box is putted way away from selected area and if i launch the game in standalone nothing is cropped, even if i select the cropped one as asset...

Expected behavior
Right cropped position also in game.

Btw great plugin!

Release the newer version for UE 5.4 pls.

用的是项目中下载的模型来渲染，为什么只渲染了6张图片

HI 感謝有這個插件，使用起來比Luma AI還好用
但我這邊有大量匯入PLY的需求
能不能加入類似Luma AI批次匯入方式(直接將PLY拉進資料夾或者匯入時可以選取多個檔案)

Great works! Need more tutorial or docs for building, thanks

I have install the last Xverse for UE5.3.2 and UE5.4.
I using the demo_fox_ga.ply

Describe the bug
When attempting to translate/move the BPGaussianActor in the scene, the Niagara particles will double-transform and if the object is rotated, the particles will transform on the incorrect axis when moved.

To Reproduce
Steps to reproduce the behavior:

1. Load a .ply into the workspace and drag blueprint into scene
2. Switch view to orthographic front/side view
3. Translate the blueprint up and down with the manipulator tool
4. notice the particles are moving 2x as fast as the manipulator tool
5. reset position to 0, and rotate the blueprint 90 degrees on the Y axis
6. Translate the blue print up and down in world space
7. notice the actor is moving on multiple axis'

Expected behavior
The niagara particles should be inheriting the precise location of the root component, and not drift away from it when transforming the actor.

Desktop (please complete the following information):

• OS: Win10
• UE Version: 5.3.2

Additional context
I could be wrong, but perhaps this has to do with a problem converting local transforms to world space?

Hey guys, great project.

I really like being able to train from within unreal's IDE.

I've been looking into 4d gaussians recently and was wondering if you guys have any plans to try and implement it.
Having 3D gaussian splats be animated in unreal would be a game changer, i believe its worth looking into.
I'm going to try to get them working myself, but i doubt i'll have much success.

If you have looked into it, could you let me know how it went?

Thanks for the great plugin!

Thanks for sharing this amazing plugin.

I just wanted to report, that I have tried it with Unreal 5.3.2 and i am experiencing some issues with the color shader:

The splats seam to be present but the colors are not rendered.

Steps to reproduce the behavior:

1. Install the Plugin and activate it
2. User plugin to import a PLY file.
3. Drag imported asset into the open level or open the asset in the BluePrint Editor
4. I can see the splat but it is grey.

I would expect to see the splat rendering in the viewport.

Describe the bug
Windows Defender has detected XV3DTools' xv1_train.exe as Wacatac.B!ml trojan.

Screenshots

Desktop:

• OS: Windows 11
• XV3DTools Version: 1.1.1

Additional context
Version 1.1.0 still exists on my system and is not affected by Windows defender. Something in the last update has flagged it on Microsoft's malware ML database, and I'm hesitant to assume it's a false-positive considering it is an exe I downloaded from an otherwise unverified Google Drive zip. If there's any way that guarantees can be made about the safety of the executable, or if any of the internals can be open sourced, I would feel a lot better about using this tool going forward.

Thanks for this awesome plugin.

I have a CineCameraActor correctly rendering depth of field for the rest of the scene (UE 5.3), but not for the splats. As I change the focus distance, the splat pops into focus all at once. Is this the expected behaviour?

FYI

I trained a 3DGS-Modell with Nerfstudio which i loaded through your plugin to ue5.3 but the loaded Modell is super laggy and has fales colors. Somehow the turnaraound explained below fixed the problem:

SOLUTION: import it to blender with the gaussian-splatting addon from here:
https://github.com/ReshotAI/gaussian-splatting-blender-addon/blob/master/blender-addon/plyfile.py
and exporting it again. It creates a file with the same size than the original one from nerfstudio, but can now be loaded corretly to XV3DGS and ue5.3

thx for your work

I just downloaded the "XV3DGS-v1.1.3-ue5.3" release package and am using it in a source build of 5.3.2.

I notice the splats show up and work, but the opacity custom code node is throwing errors on my end.

If I make opacity 1 or either the con_o input, I see the splat incorrectly, so i know everything else is working, except the material.

Any help would be appreicated!
Thank you!

Would love it if the plugin can be built with linux in mind so we can build a project for it.

Thanks.

How difficult for the current plugin is to support antialiased GS asset trained from splatfacto (nerfstudio)? I think the change could be relatively small. See mkkellogg/GaussianSplats3D#142 how a web viewer implements the antialiased mode.

The resolution of the Gaussian Splatting capture is lower than expected.

Steps to reproduce the behavior:

1. I have downloaded the plugin for UE5.2 and directly placed the 'XV3dGS' folder into the 'Plugins' folder.
2. After enabling the plugin, the button to import appeared, and I used it to import the .ply file.
3. I imported a .ply with 30,000 points.
   
4. The resolution of the image is much lower than expected, seems that it's about 1400 instead the 30000 points.
   
   

Do you have any suggestions to try to solve this?

Thank you!!

Thank you for the amazing work. I' m currently working on UE4.27 and I want to use this plugin in UE4. Will this plugin support UE4 in the future. Or Is it possible that I transplant it into UE4 ?

Describe the bug

Even if I disabled all culling options in the settings panel, the culling cannot be disabled.

Environement:

• OS: Windows 11

I'm trying to export to Android build for VR (Quest 2), and get the prompt that the module is not available on the platform. Is there a way to build for Android (VR) to get around this error?

When trying to make the packaging of the project in UE 5.4, I get an error when cooking the material that prevents me from continuing the process.
