The Blender 3.0 splash screen scene will not be rendered as shown in the reference: https://cloud.blender.org/p/gallery/617933e9b7b35ce1e1c01066
The bird and hair details are missing.[fixed already]The lower teeth will intersect with the lower lips.
Exact steps for others to reproduce the error

the scene looks like this. Incomplete with teeth intersection.In 3.0.0 Alpha, branch: master, commit date: 2021-10-26 23:24, hash:

the result in the viewport looks complete and correct.Rendering looks also fine.

Thanks for finding working version, I was unable to find one locally. Will bisect exact commit
You're welcome. I found the working version due to another bug report. It looks like the latest 3.0 beta is a headache for the development team due to more issues. I hope you get everything solved asap. This is the best development progress with good communication I ever experienced since I started 3D at the end of the '80s. ;-)
So far it looks like
1a7757b0bc
caused issue with teeth intersecting. Rendering crashes at this revision, also I suspect missing bird will be different issue.Since example .blend file was updates along with this commit, I assume this is intentional change

Missing bird is caused by

. Here I am not sure if functional changes were expected.CC @mont29
Thanks! Issue regarding missing birds and overrides is found and fix is imminent.
The version: 3.0.0 Alpha, branch: master, commit date: 2021-10-26 23:24, hash:
8d8ce64435
seems to handle the splash screen scene as expected now except the hairs of the character.Added subscriber: @dfelinto
~@Renderbicks your build is prior to the fix Bastien committed. Can you double-check if the problem persist? Here it seems to be fixed.~ intersection persist
I guess this is the teeth intersection issue: {F11995886, size=full}
Confirmed also that reverting
1a7757b0bc
fixes the issue. Now it is a matter of finding out whether the fix is correct and the .blend needs to be corrected, or the fix can be reverted.Blender 3.0 splash screen scene will appear incomplete and rendered incorrectlyto Blender 3.0 splash screen scene will rendered incorrectlyAdded subscriber: @brecht

changes the order of vertices output by the mirror modifier. The surface deform modifier depends on this order, and doing an Unbind & Bind on all surface deform modifiers in ellie.blend fixes the problem.This can't be fixed with versioning really, running surface bind can't be done as part of that. I also don't see a practical solution to #91444 that keeps the vertex order.
I suggest we accept the compatibility breaking, mention it in the release notes and update the splash .blend file.
Bastien is looking at that and will address the final problem (either by reverting or by fixing the problem).

I missed taking a closer look. Not fixed in the last night's build.

I think it's fixed, but the current uploaded version of Ellie was saved with the broken version.
Before I updated my 3.0 and 3.1 builds today, if I bound the Surface Deform in one, it wouldn't work in the other (both ways).
After updating to latest 3.0 and 3.1, the bindings are cross-compatible. So I think this is fixed. I will now update Ellie's file on the Studio Website so that it's no longer bound with a broken version of 3.1. (Edit: Done!)
Just for the records I have just updated the splash screen .blend file with the teeth manually fixed. The file was still in a limbo state since it was saved with a version of Blender where the error was still present.
