Bug How to override canvas rect transform scale value

So i wanted to create a custom canvas scaler , but canvas rect transform value is driven by canvas , so it makes sense if the scale value is driven by canvas IF there is canvas scaler , so i deleted canvas scaler , to my surprise scale value in canvas rect transform is still driven by canvas even though the canvas no longer control scale value in any mean . So how do i override this setting and change the scale value in rect transform while keeping canvas component ?

 

Could you use panel?

 

can you please describe what you want to achieve?

 

I already described it , i want to create my own canvas scaler script , but i can't do it because canvas rect transform data is being driven by canvas

 

Obviously you didn't dive very deep yet and didn't start to write your own canvas scaler.
if you would have done research, you probably would have already checked out the source code of the default CanvasScaler you would have noticed that this script simply sets the

scaleFactor

and

referencePixelsPerUniy

of the

Canvas

. So, if you remove the canvas scaler, the previous values remain in the Canvas.

 

Oh so it mean my script will still work despite unity saying in the editor that "some value is driven by canvas" ?? thank you !!!
