Two issues encountered with the update to 3.5.34
first one I noticed is that after the update 4 of my IKs were corrupted and were no longer responsive to the bones that they were attached to. (The bones still behaved normally though). All other IKs were functioning as per usual though. I deleted the IKs and recreated them, 2 of 4 worked, but the following two refuse to work at all.
Second issue, is after exporting a new model into unity, the model shows up invisible. When exporting an existing and working model under the new version, I get a message saying that it can't read the json for the first animation in the list. If i go back to Spine and remove that animation, then re-export, it says the same thing with the new first animation in the list.
I have reacquired the Spine Unity plugin thinking maybe you had updated it to fix this, however it doesn't seem to have helped at all.
(Sorry if this reposts, the forums are being very buggy for me. Can't upload pictures because it clears the text, and attempted to submit before and the post never submitted)
Okay, so the IK picture i'm guessing is too big. This is the unity error though, seems to have attached this time
to add to this, hopefully it helps. Comparing the two spine models in unity (the old version that works, and the new that is invisible), the materials for the new one are empty. Being overridden by editor scripts it would seem also as can't manually insert them either.
