I render a texture on the depthFade gradient and would like to rotate it corresponding to the gradient’s direction (see image)
My idea was to calculate a 2D Vector (XY) representing the depthFade direction from top view.
Then get the angle between that one and the x-axis and rotate my texture by that.
Sadly i have no clue how to get the 2D Vector respresenting the gradient’s direction, but maybe someone of you got a tip for me OR has a different solution
