Project disappears when trying to zoom

Bug Report
1

Hey! I’ve been working on a project now for a few weeks and I’ve noticed some strange behavior from the app today. Most is annoying, but ultimately fixable (objects from scene randomly deleting, layers disappearing, etc.).
The one that is giving me the most grief is that my entire project will disappear from view if I try to two-finger zoom in/out. I can only get it back by closing the app but it does it again immediately upon trying to zoom in or out.

These are the steps I’ve taken to troubleshoot so far:

Powercyle iPad
Close Nomad Sculpt and relaunch
Slowly zooming in or out (same result)
Making all objects invisible, then visible one by one (no effect)
Opened different saved project, same actions provide same results

I’m currently using an iPad pro 6th Gen running iPadOS 18.1.1 and Nomad Sculpt 1.90.

Any help would be greatly appreciated, I’m very new to this type of art/creation and I’ve absolutely fallen in love. This project went from a “trial and error” thing I was playing with to learn and developed into something I was really proud of and now I’m quite worried :frowning:

Thanks in advance!

Test your file in the WebDemo.
It may be a problem that has already been fixed in the upcoming update.

I was getting this error as well . The only way I could fix was to merge all my objects together, export as OBJ then import and separate everything , and rebuild subdiv levels , was super annoying

If everything disappears it means there is some infinite values in the mesh coordinates, everything will go wrong after that, on most softwares.

It’s hard to pinpoint the issue (lot of algorithm, different operations in the app, etc).

But I added a check at loading time to try to detect buggy stuffs like.
Bult ultimately it’s a bit too late since the mesh is already more or less already corrupted (but the check/fix can help in some cases though).
