I used the transitions included in the newbluefx freely distributed plugin in the last Vegas version 20. However, after changing to version 21, it seems that the transitions and plug-ins used in version 20 can no longer be used.
I think I've seen other users' posts saying that they can't use plugins while updating from 20 to 21, but I'm not sure if it's exactly the same as mine.
Are there any differences in the approval of plugins supported by newbluefx, etc. between Vegas versions 20 and 21? If you load a file that was worked on in 20 into 21, there will be no trace of the transition applied.
And how should the transitions with red 'X' in version 21 be unlocked? I installed only Vegas 21 version without installing any additional plugins, but I am curious as to why the X appears.
