Gaussian Splatting: Significant quality loss when unified is enabled on multiple entities
When enabling unified rendering on more than one gaussian entity, image quality degrades noticeably. With a single splat, it looks correct without ordering it.
Sample:
One model without unified https://www.scanmenow.es/samples/dev/tmp/?model=model Two models with unified https://www.scanmenow.es/samples/dev/tmp/?model=model2
Updated to 2.12 it 'feels' faster and more responsive unfortunately the issue seems to be still there (you can check on the same url)
Btw congrats for the release!
Hi .. thanks for the repro, I confirmed this is fixed in my PR where I added needed functionality. Please reopen if you still see some issue. The engine with this should be out in the near future ( a week maybe), but you can test with local engine if needed.
@mvaligursky Unfortunately, although it looks much better now it still has some small glitches (attached video), maybe ordering issues?
@slimbuck @mvaligursky Uppps it was on the desktop browser in the Android one (tested with Chrome and Brave) looks really bad (and it was working with the previous version with some small glitches but working.

do you have the same issue with the engine examples using unified, such as this: https://playcanvas.vercel.app/#/gaussian-splatting/global-sorting ?
I can reproduce this on browser stack using your ply This PR is causing the issue: https://github.com/playcanvas/engine/pull/8055
missing
highp?
Tried those first, so probably not. It affects WebGPU as well, so not highp issue.
I have a workaround here, seems GPU / driver issue. I'll release engine patch in the next few days.
@MotivaCG - if by any chance you have one of those awesome character splats (individual or a small group) you could contribute to this repo, I'd be very much be in favor, please let me know. They look awesome and are a great test case too.

you mean the pub or the characters?
Some character splats - one / two characters in a single scene, or anything like that.
uncompressed ply - that way I can convert it to any format without loss. Much appreciated!
This is now released: https://github.com/playcanvas/engine/releases/tag/v2.13.1
It is 99.9% done! when the canvas is resized (ie. a screen rotation on a smartphone) the problem appears unti you trigger a render by moving the camera or whatever.
Btw these kind of assets work for you? https://www.scanmenow.es/samples/leonyyo.ply https://www.scanmenow.es/samples/8yq7294ui.ply

interesting, I'll see if I can repro, thanks!

Yes, I'd be happy if I can use some of these!

I posted them to be used (I'm the one with the moustache hahaha)
@mvaligursky really easy to replicate issue in computer

Great video, thanks for that, I've fixed it and we'll release it in the next few days.
And thanks for the splat models, I'll be using them in some future example for sure, much appreciated.
