as the title says, I have modelled an object using a subdivision surface modifier, and I need some of the edges to be straight. For that I have used a combination of some crude control edges, but mostly using a mean crease to define the edges I want straight. This works for all cases except for the corners, here it look like it works, but then the modifier goes over the edge and smoothes it out, which is not what I want. See picture below.
and this is how it looks from above
and this is what I want it to look like
and this is the topology view(note that this happens in multiple places, but all have similar geometry to this one)
