Question Make some UI stay the same size when moved

I have the canvas set to World Space and the camera to perspective,
I need a way for some elements to have a constant size, like if they were in orthographic view, i would like to know if that's possible

Currently if i move the ui back and forth it looks like it changes size because of the camera projection, like this:


Since i'm using a world space canvas, i have to sort the object by moving them closer to the camera, which makes the ui grow and shrink, making the grids be all of different sizes

I could use an orthographic camera, but i like the effect the FOV gives to the UI.
I would appreciate any help or ideas on how to make this work

 

I think i found how to solve it, i made another canvas for the elements i want to be orthographic and then synced their positions using WorldToViewportPoint, but the problem now is that it's giving me the wrong position

Edit:
Nevermind, the new canvas is always rendering on top, which i don't want, i think i'll have to go full orthographic
