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. It’s easy to fix;
-Some variables now don’t work alone, you need the ‘var’ word before. Like “var variable = 0” insted just “variable = 0”
-Some expressions, like some used on DUIK per example, used old expressions name that need to be updated, like “this_comp”, that must to be written as “thisComp” 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 don’t know what’s going on.
