Hey there, while taking a look at the fantastic 2d filters made by Martinsh, i noticed something, the hdr in Martinsh’s blend adjusts as you look up and down, and it doesn’t when you throw it into your own blend file, and while i scavenged around the original hdr blend, i could not, for the life of me, find out how he achieved the adjusting effect. So i figured i’d make my own method.
[BEST USED WITH RESTRICTED MOUSELOOK]
My method is having the basic character/camera mouselook setup, then having the empty that controls the 2d filters set exactly on top of the camera, and then the camera parented to that empty, then align as many cubes as you want (the more cubes, the smoother the transition), align them in condescending order (one in the middle, one above the middle, one below the middle, one at the top, and one at the bottom) (again the more cubes the smoother the transition),
CUBES MUST STAY ON THE EXACT AXIS OF THE CAMERA/FILTER CONTROLLER
add a ray to the filter controller empty, adjust it according to your own preferences, so that in the end, when the ray hits the middle cube, the property that controls the HDR is set to a reasonable amount, when it hits the one below that, the hdr property is set to a reasonably dark amount, then when it hits the bottom one, the hdr property gets set to a very dark amount, when the ray hits the cube above the middle, it gets set to a reasonably bright amount, and finally when the ray hits the cube at the top, the hdr property gets set to a very bright amount.
[NOTICE] In my blend, the HDR property is on the empty named FX, and the property itself is called “HDRamount”, also, the higher the property number, the darker, and the lower the property number, the brighter
The character cube is the parent of all the cubes, as the character cube rotates left and right, but does not rotate up and down, the camera is the parent of the filter controller empty.
