Problem with Mask and Canvas (Sort Order)

I have problems with a mask.
I have GameObject. His name "testt"

it is necessary for me that this element was higher than all. Therefore I added Canvas and exposed Sort Order = 150. This GameObject is in "Panel" with Mask


But GameObject it isn't visible! When I disable Mask, all is visible. Is it normal? The screen is lower




I hope an essence of a problem it is clear. My English is poor. I hope for any help

 

The MASK component is there to obscure drawing behind the mask. So if your object is HIDDEN when the mask is enabled and it is VISIBLE when the mask is disabled. Then that is correct behaviour.

However, given your placement of the Mask component on the parent panel, it is odd why only one graphic is hidden and not the entire panel.

 

Thanks for the answer!

This behavior strange seems to me. When I add CANVAS and "override sorting", my Game Object disappears

 

If you override sorting, then you need to manage it, so if it's behind other 3D elements in the camera's view, it won't be drawn.
TBH, I wouldn't use that setting unless you REALLY had to
