Sprite render geometry in Blueprint

Hi everyone,

I’m trying to create a system where the user can draw a mask that hides part of a texture. One way that seemed promising to me was to use a paper2D sprite since it allows for fully customizable shapes to be draw to set what will be rendered. But I can’t find a way to access any of the parameters through blueprint. Am I missing something here or is just not available ? Does anyone know if it would be accessible in C++ ?

I’m still thinking of other ways to do my mask, if anyone has suggestions I’m very happy to read them :wink:

I attached a picture of the parameters I’m trying to edit via Blueprint. I’d like to be able to change the number and position of the vertices.

Thanks !
