    Color the world in real time

    Hi guys,

    I am working on a game about colors and poesy so I am trying to make something like "painting" colors.

    like this basically:


    I am not talking about writing on textures directly I'm talking about a sort of a brush that is erasing a filter.
    the "filter" can be a "3D layer" like this:

    (but I'm wondering if having 2 scene at same time can be too heavy...)

    I tried somethings based on customDepth but it create a lot of problems (basically I cannot make it persistent and the customDepth obviously create depth problems...)

    So I'm wondering if you guys have an idea on how could I implement this (just an idea to know where I could try to search will be very helpful )

    So For now I did this:

    On a mesh object.
    The world position offset is clearly not mandatory but I think it's beautiful
    It "work" but this is definitely not as beautiful as the examples I posted before...

      I tried a new approach which is looking better, more "progressive" more like painting:

      I did this using post processing. my post process material looks like this (before tone mapping):

      But my problem is still to make it permanent... It seems it's impossible to write on a texture from the material itself (it's completely fine it I just write in the VRam, make this colouration savable is not my priority now)
