FORT-900659 has been created and its status is ā€˜Unconfirmed’. This is now in a queue to be reproduced and confirmed.

We are also having the problem, we haven’t been able to cook since the 35.00 update.

Same for me, was completely fine before v35.00

All our projects now have this issue. Error says ā€œasset too bigā€ if you follow through on output log. Tested with 4 platforms, 2 diff server regions, and 4 different projects. I was told its either niagara particles, or NPC character definitions. All our large projects can’t launch.

Treat this as pri 0 please.

Here is the error happening for me: 8280716b-424d-5ef0-3b55-6eaf83b85c3f

We are checking into this.

when launching a session its now saying the following, was in a session and pushed changes and now this comes up.

ive done local diagnostics, restarted PC, restarted routers and tried on backup network with same issue.

+1 having this issue as well, for now a temp fix was to roll back via snapshot to get it working, so whatever changes you do, keep pushing them so you can roll back whenever you face this issue

I noticed when I opened UEFN after the v35.0.0 update there was some modifications to the vfx devices in my game. When I went to launch the session, I ended up getting the same cook error that others are facing. I managed to workaround this issue by deleting and remaking my 1 niagara effect in the game that was associated with the vfx devices.

See if you can try and chase down any assets in the revision history that got corrupted after the update. Like I mentioned, I saw the vfx devices get modified when I went to checkin my changes, and that’s really the only way I was able to ascertain that they were the specific issue and resolve it.

Could we get folks to try again?

Yep works for me now, thank you!

Also this issue here seems to be solved as well: Validation error on Verse files under /sys/public folder that are giving asset identification errors. - #3 by flyingpigbaby

I’m still having the same issue on my island—getting a cook failure message. My game was working fine earlier today, but the error started showing up after I relaunched it. Would really appreciate any help or solutions.

Had same issue when connected Mutator Zone events to Prop Mover. Deleted the mutator zone and works fine. So it fails to reply what causes the error and tries to cook.

Still having the issue :confused:

I HAVE noticed that it tends to happen when custom verse devices specifically are deleted, as well as certain content browser assets ( for me it was some npc definitions and vfx)?
