A ? about new sculptie 'mirror' feature

It's great that we are now able to use these new features using the latest ReleaseCandidate viewer, however sculpts that use these options appear 'broken' when viewed by someone using the main client (nonRC)

They are NOT visible as mirrored and topology is changed from sphere to cylinder causing the sculpt to appear sliced...thus rendering this feature useless until mirror is applied across the board. (?)

any ETA on when it will be available on all viewers ?? TIA

I really doubt LL would bother to spend time integrating the chance in pre-1.21 viewers.

The majority will be on 1.21 a while after it goes release, with a minority using 1.18.x, 1.19.x and 1.20.x official viewers still and another minority using pre-1.21 third party viewers (ie Nicholaz).

The only way those two minorities would be forced to upgrade to 1.21 (or later) is for LL to break the network protocols so they simply can no longer connect at all.

For the next few months you'll always have a few people who will not see the new sculpt features properly.

i think thats why they are called Test Viewers they are not to be used for main content at this time. also they can remove any of those features when the time comes to update the main client it has happened before.
and i would not believe any ETA on when its will happen the have never stuck to a date LOL
