DId just test one template of mine, yes, it does not work at all. AE is unresponsive and the timeline cursor keeps ending up in the wrong place, totally unusable.
CC2019 is the worst update by far. Premiere has a lot of bugs as well.
About the expressions: We can choose what expression engine we want to use:
-Legacy Extend Script - The same used in all AE versions;
-Java Script - The new one.
When I choose the Java Script, some errors happens:
-If and Else statment - This is the problem that you @Creattive mentioned. Itâs easy to fix;
-Some variables now donât work alone, you need the âvarâ word before. Like âvar variable = 0â insted just âvariable = 0â
-Some expressions, like some used on DUIK per example, used old expressions name that need to be updated, like âthis_compâ, that must to be written as âthisCompâ now.
But my problem is that the project just crash, before you be able to choose what expression engine do you need, exactily as you described that happened to you.
It may have something to do with the GPU updates that was been made. I really donât know whatâs going on.
Did you try to open the project with caps lock enabled? That disables the rendering of the current frame, and also should disable the calculation of any expression.
Did find out that the totally unusable GUI performance was due to a text layerâs source text linked to a master control in the essential graphics panel.
If the essential graphics panel is closed, everything works like a charm.
If the text link to the master property is deleted from the Essential Graphics panel, everything works as well.
Its always like that with newest AE. They will update it , patch those holes. Adobe is very well aware of template world. Adobe is super happy about template world and template market. So surely they will update any issues. Templates are one of the biggest indirect AE promoters.
Dont worry i am sure that at least 5-7 versions down will always be supported and compatible with newest AE.
Ps: fun fact i had some items bought by ADOBE and MICROSOFT :))) and also you can find adobe forums with staff chating about template world.
