Getting something similar - one corner now fails to show (bottom left) and for the first 2 seconds it's saying media offline. Not familiar enough with Fusion to figure a workaround. Oddly the corner that is showing (top right) is tagged as the 'left' corner in the settings tab when I select the templatae in the timeline. Another odd thing is the position seems way off (far, far out to the right instead of closer to the text as before).
i did a project using these a few months ago and had to revisit it today for an update to find none of the lower thirds work as before.
UPDATE: Yep, last couple of seconds black as well - so removed the KeyframeStretcher node (thanks George) but still have the issue with a single corner instead of two (I'm sure there used to be two and I'm not imagining it) and the position of that corner etc. I'll grin and bear it.
UPDATE 2:
Awkward as hell workaround but it's nearly 2am and I'm done with this : ) :
Followed the brilliant instructions here:
viewtopic.php?f=21&t=99109But was stil lacking the corners. Realised that the single line version is fine, so just aligned the single line lower third in the right place and deleted the text on it - so i have a layer with no text but corners and a layer with text but no corners (cropped them).
Meh.
