Question How to import a sprite mask from a file

Hello all this is my problem :

I want to import a black-and-white texture from an image file (using LoadImage), convert it into a sprite (using Sprite.Create), and use it as a sprite mask (with the Sprite Mask component).

I have done the above steps, however my problem is that the Sprite Mask uses its sprite's alpha channel, and I do not know how to import my texture into a format that will work with the sprite renderer.

If I import a sprite into the asset menu, and select "From Gray Scale" as the alpha source in the texture import settings, this does what I want to do, however I do not know how to do this in code

I would rather not write a function that converts the texture into the format I want, but have no problems with it if it must be done.


Edit : the texture converter runs far faster than I though, so I will use that for now, but I still wonder if there is a better way

 

instead of black and white just make a png and delete the pixels that are supposed to be transparent in the mask

load image imports the alpha of the image if you load a png

 

Thank you for your reply, however the mask image needs to be grayscale
