export size

[lesath3d]

hello, I can't save as files which are bigger than 1,5GB and 6,5mill splats. if the limitation would be at least 10mill splats and 2-2,5GB for the detailed/big scans, that would be great.

Hi @lesath3d ,

My macbook can export much larger scenes than that!

Few questions:

1. what happens when you attempt to save?
2. which platform and browser is this?
3. which export format is this?

Thanks!

1.: Error Loading File: Array buffer allocation failed while saving file
2.: Chrome
3.: Im using the "Save as", but it happens every single type of export

[slimbuck]

Thanks, which platform? (Machine and OS)

[lesath3d]

win 11 pro, 64gb ram, rtx 3090, ryzen 9 5900X

Is that a file that you can provide for testing?
Is that something that happened once or can you somehow load but not save the file?
I once ran into the issue, that my undo-memory blew the app. I was able to save my work by clearing that manually in the guts of the memory :)
Thats the reason for implementing the Selection-Compression PR that aparently nobody is interested in #207

I loaded & cleaned some splats and I cant save out with "save as". I deleted the half and saved out, hit undo, invert, delete that part as well, saved out. I think it shouldn't the memory issue.

Well, with every selection you make you increase the memory usage. I would suggest some kind of emergency-save function, that can be used in case the normal save fails. The emergency save would then warn the user and allow purging all memory that is not required for saving. Still, I assume that at some point the browser will need at least two times the size of the loaded data as memory. And chrome at least on Windows might have a hard limit there.

Gemini says that the maximum memory per tab for chrome on Windows is 1.8GB. For Firefox its 32GB.

Okay there are some techniques to get around this limitation. SharedBuffers for example. And right now you can either start chrome with command line options that allow more memory or set certain flags for that

[lesath3d]

I increased the values of all the chaches/buffers, firefox is much better, but the limitation is still 2GB(chrome only 1,5). Id love a stand alone software :P

@lesath3d Have you tried installing SuperSplat as a PWA?

I'm wondering whether Chrome will grant SuperSplat more memory in that mode.

[lesath3d]

just tried, but still firefox looks the best. that can save until 2GB.
I tried on another PC with ryzen 9 5900X, 128gb ram and rtx 6000 ada, but same result

[simonbethke]

hm, I cannot confirm this behavior. I just stored a 3.6GB file with chrome on windows.

Hi @lesath3d

Did you find any solution here? I don't think the issue is on our side, but more likely your platform or browser settings. Since we can't control the browser memory limits and can't replicate the issue, I'm going to close this ticket.

If you manage to figure out what the issue is/was, please let us know.

And feel free to reopen the issue if you think there is something we can do to help.

[lesath3d]

hello @slimbuck ,
sadly no. The limits on firefox is 2 gb at this moment. This looks the best option now, When I need to do anything with bigger splats I'm going to split it to parts and merge them with another software. I'd love to reopen this ticket, but if you can't do anything it looks pointless now.

This sounds almost as if you were using a 32bit version of the browser
