1.12.2 stuck while loading a collection

The editor shows the following errors:

java.lang.IllegalArgumentException: Invalid render-transform-key? argument: editor.math$render_transform_key_QMARK_@540a4a1a

and

clojure.lang.ExceptionInfo: handler ‘:edit.cut’ in context ‘:workbench’ failed at ‘:enabled?’ with message ‘Invalid render-transform-key? argument: editor.math$render_transform_key_QMARK_@540a4a1a’
java.lang.IllegalArgumentException: Invalid render-transform-key? argument: editor.math$render_transform_key_QMARK_@540a4a1a

while loading a collection and is stuck forever. The same collection was read by 1.12.1 without any issue.

Other collections are read with no issue by 1.12.2. Moreover, the project can be build and runs completely fine.

Can you share the project?

roccosaienz · March 8, 2026, 2:27pm

Yes, of course. I am sending to you an invitation for the repository.

Many, many Thanks!

Thanks, and which collection is causing you problems?

play.collection in main/play/

Thanks!

Hey Bjorn, have you had the chance to take a look at this problem? I updated to 1.12.3 but I still have the same problem…

Sorry for the delay. Mats and Vlad are investigating it right now!

Hi! We’ve found the issue and patched it. Turns out there was a problem around rendering Models with Materials that used world-space vertex attributes.

The fix is building on CI now. Hopefully you should see an editor update notification to 1.12.3 in about an hour or so.

Thanks for reporting!
