If I create a mogrt in AE and bring it into PPro, any sliders I added cannot (easily) have non-integer values. For example, I have just made a mogrt where you can specify (in seconds) the time before a piece of text fades off. This would normally be somewhere around 5 seconds...maybe 4.5....maybe 8.3....whatever. But the only way for the PPro user to specify these decimal values is to click on the number and type in the value - not very user-friendly. And then, the value displayed beside the slider is an integer - not the actual value.
A solution to this would be if, when creating the mogrt in AE, we had some kind of "precision" attribute we could set, and PPro would respect this and display the value with the correct number of decimal places. And the slider woudn't round the value to integers when being dragged.
I have some similar MOGRTs with time adjustment options and agree this would be very useful and much more user friendly than having to type the value every time. All other text fields for non-MOGRT properties show 1 decimal place by default and when you click in the field, you can see any additional decimal places. This should be the same for MORGT values without having to specify anything in AE.
