Gaussian splat render error

🌵 Needle Engine

The quality of my splat is very low in the build.

To address the low quality of Gaussian splat rendering in your build, consider the following steps:

  1. Check Renderer Settings: Ensure that the SplatRenderer is configured correctly. Verify the resolution and quality settings within the renderer. Adjust the resolution settings if they appear too low (see the documentation).

  2. Optimize Shader Parameters: Ensure that shader parameters, such as the Gaussian sigma and any blurring parameters, are set to values that maintain quality without excessive blurring (see the documentation) (see the documentation).

  3. LOD and Blending: Check if the Level of Detail (LOD) settings and blending modes are properly configured to maintain quality at the required distances (see the documentation).

  4. Progressive Loading and Materials: Ensure that the materials are not suffering from issues related to progressive texture loading. This could degrade quality if textures are not fully loaded (see the documentation).

  5. Debugging and Profiling: Utilize debugging tools or logging to identify any unexpected behavior or errors during rendering. This might involve verification of shaders or reviewing the rendering pipeline for bottlenecks.

For detailed adjustments or if you’re encountering specific error messages, it may be useful to trace any logs or utilize debugging features available within Needle Engine (see the documentation) (see the documentation).

Please let me know if there are specific configurations you’ve tried or if additional guidance is needed!

Could you add some more info so we can help? :slight_smile:

  • which version of Needle are you using
  • which version of the SplatRenderer are you using
  • do you have a link
  • does it look different in a local server vs. a build, and can you post screenshots of that?

Thanks!

I’m using version 3.48.3. Turns out the problem was with the exported ply version. I am using scaniverse. It fixed the problem but in AR it always way up in the Y-axis.

Is there something wrong with AR for gaussian splat? Even the sample scene for gaussian in AR is too high. I also tried adding drag controls so i can move it in AR. Doesn’t work.

@saad_baig have you tried updating your Needle Engine version or is there anything blocking you from doing that? (e.g. to the latest stable 3.51.2). The version you’re using is already 3 months behind

Ohh I didn’t realize. I downloaded the gaussian sample and start building on that. I’ll test it on the new version.

I updated my version to 3.51.2. The issue still persist. You can try it out here.

Can you try disabling AutoCenter ?

I think it’s placed visually further up because of the big cylinder in the scene (which fades out to the bottom making it appear as if it was floating high above)

Thanks marcel. Disabling autocenter fixed the problem.
However iOS quicklook doesn’t render the splat.

iOS QuickLook doesn’t currently support Gaussian Splat rendering, which is a limitation by Apple, not by Needle.
