Viewing Gaussian splats while inside the model

I am trying to view immersive environments that are Gaussian Splats created by marble [dot] worldlabs [dot] ai. For example, here is one named "Steampunk City Night View":

(Note: the low-res version is 500,000 splats, so I am just testing the first 200,000 splats).

But when I try to view it at scale, nothing appears.

I tried shrinking it down (scale factor of 0.00595458) and positioning it in front of me, and I could see the content, so the parsing of the PLY file is working. Example:

But when I move into the model, it goes clear, also hiding virtual content behind it that is also in the splats' space (like the Mac virtual screen). Example:

It is as if when I move inside the Gaussian Splats' bounding box, it sets an opacity material on the splats.

This prevents me from using these Gaussian Splats as immersive environments.

Is there any way to disable this behavior?

Hey @THeberlein,

My coworker added some great tips in this thread including chunking the splat to limit this behavior.

There's no supported way for you to control over how splats are culled with the APIs currently available. If you'd like us to consider adding the necessary functionality, please file an enhancement request using Feedback Assistant. Once you file the request, please post the FB number here.

If you're not familiar with how to file enhancement requests, take a look at Bug Reporting: How and Why?

Thanks,
Michael
