I’m trying to create an animation for a UMG Widget it the designer. Adding keyframes works for both float and vector properties when using the simple timeline, but when using the curve editor, only vector properties are visible, so I can’t change tangents of float curve animations.
This behavior appears to be present in both 4.8.3 and 4.9
We’re also seeing the same issue in 4.9.1; in our case it is a custom float property. I can set keys on the regular track but when I switch to the curve editor nothing appears. It can be reproduced in a clean project.
Steps I used to reproduce in a clean project:
Create a new UMG widget, “AnimatedFloatText”
– Add a variable called “FloatValue”
– Add a function called “SetFloatValue” that passes an input float to FloatValue’s setter
– Add a child Text widget
– Bind the Text property to a new function that returns FloatValue as text
Create another UMG widget, “MainWidget”
– Add a child AnimatedFloatText widget
Add a new animation
Inside the animation, add the AnimatedFloatText and then the FloatValue track
In the key editor, add keys at 0 and 1 seconds
Switch to Curve Editor, notice that no curves or keys appear and the different zoom to fit buttons do nothing
I was able to reproduce this issue on our end. I have written up a report (UE-21391) and I have submitted it to the devleopers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.
