Can you try checking if this one works: Simple Fog of War | Babylon.js Playground (babylonjs.com) ?

I can confirm, it is working greatly now!

@slin

Passing an vec3 array of unit positions is supported on WebGL2, but not WebGL1. Also if this array size is at scale of tens and hundreds, it adds overhead to loop through this array in fragment shader to check if fogOfWar or regular color should be applied. In addition to fog of war, you might also want to have custom fragment shader for highlighting a group of selected units. That will also add more overhead.

That seems I won’t be able to do this with shaders. Let’s see who else kick-in with their experience
