Unity light cookies with MRTK

Hi, I am kinda new to Hololens development, I wanted to place a spotlight, switchable by a toggle button and use a Unity light cookie on that spotlight to project a simple crosshair onto my hologram.

Now I can't get light cookies to work in my Project. I created my cookie to Unity specification, and the cookie works in a normal Unity 3D Project.

My suspicion is that, since cookies use a black/white image to define where to project light, the Hololens -where black is seen as transparant- does not work with light cookies. Is my suspicion right? Or is there a special process to get light cookies to work?
Or could the shaders be a reason?

Thanks a lot!



  • For anyone bumping into this, I found the solution.
    The spotlights Render Mode needed to be set to important.
    Now let's hope this does not influence performance to much
