left model is after i apply resetxform and collapse it, right one is how it should look, but after exporting and importing it back i get same issue and ends up looking like the left one.
I have faced the same issue, in case of wrong topology quadrifying helps or HSDS modifier, also I found, that applying smooth modifier to your model can solve smoothing problems.

hah, no, i was getting baking issues as well - so it's definitely the model.
anyway i fixed it by turning it to editable patch and using graphite modeling tools - quadify all.
pretty weird.
