How to alter the Perspective Grid to match an image?
Cannot for the life of me work out how to adjust the perspective grid to match my image. My image is a photo of 3 boxes piled up on top of eachother. I'm moving the anchor points and can see I'm changing the grid, but it's nowhere near where I need it to be. So confused, is anyone able to help...?! I thought maybe 3-point grid for this one but I'm a beginner so wasn't sure.
