Cannot raycast though unmasked areas

[PalaNolho]

Not sure if it's a Bug or Feature request.

It's not possible to raycast though the mask subtract.

Imagine that you have a mask that occupies the whole screen and then you have inside an dark color image to dim the screen.
Ans them under it you have Masking shapers (Subtraact) to remove certain areas of the mask that you want the user to see underneath and you want the user to be able to click on what behind

At the moment it doesn't seem to be possible.
The only way to make it happen was uncheck the "Raycast target" from all images from the mask, which beats the purpose of not allowing to click where the mask is in place.

The way I see it should work is:

• if it's masked, block raycast (or not) based on the raycast flag on the image
• if not masked (or masked with subtract) then it should not block raycast (or it could still use the flag on that image to control it, but it should be possible to choose to not clock in those areas

thanks

(in the image below, the grey is an image stretching to occupy the whole mask and the white are the maskable objects set to subtract)

Thank you for your reporting!

By the way, it looks like you are using both SoftMaskForUGUI and UnmaskForUGUI.
I don't recommend combining these two.

• Essentially, the SoftMaskForUGUI package is a superior alternative to UnmaskForUGUI.
• The MaskingShape and RectTransformFitter components provide the same functionality as the Unmask component.
• If you don't need soft masking, you can use the "Anti Aliasing Mode" instead.
• SoftMaskForUGUI does not need to use a raycast filter.

i'm not, I just tried both separatly 👍 (the guidance you provided on the unmask worked btw).

So tested what you sent and nop, didnt work (the file only got a canvas.prefab, not sure if that's what you meant to send.

not sure if relevant, but i'm on Unity 6.0.29f1

Most likely, this is because there is no EventSystem in the scene.

I did try that scene too but still doesnt work
I'm a but confused on why :(

I literally opened your scene and played it but the buttons doesn't get interacted with.

if there anything I can do to try to understand why it's not working ?

Not sure if relevant but,

• the items I'm trying to interact with are on the world canvas while the dim with the cutout is on the overlay
• as mentioned before, he unmask asset approach works and I'm just having problems when trying to use Softmaks with subtract
