You can then check this texture in shader to know if you've seen the pixel before. 2) If you constrain the view to be orthogonal (at an angle - so isometric) then you'll have a 2d view of the world, and you can paint the visible scene onto a mega texture to record the level that you've seen. | |

Most notorious being that the mesh is 2D, it's not feasible to do volumetric raycasting due to performance reasons, and if I render the 2D mesh to the camera as some form of mask - I get artifacts along walls and similar where the player doesn't see "above" the mesh even though they should. This is solvable by raycast upwards from the mesh outline, but it's not very elegant and not really feasible in terms of performance either. I was really hoping this would be solveable via a screenspace shader instead. | |
