Hello, the InterpolationWeightY parameter for instances is broken.
When it is deactivated, it is applied. When it is activated, it is not applied.
Secondly, the text field is very difficult to edit: As soon as a digit is entered, the text field is exited. So in order to write “160”, for example, you need to click into the field three times and enter the number one digit at a time.
As fare as I can see, deactivating the parameter should work. Do you have a file where it still is applied? It might be that not all places that preview the interpolation are update properly?
Using Instance as Master also added the instance with the deactivated parameter applied, so it’s not just the preview. I can send you the file tomorrow.
