Im modelling an asteroid and have used BWF to produce a near perfect sphere (very little noise) with a number of protruding craters. The problem im having is that the ridge of the craters (where they stop rising and begin to fall) is very messy and blocky.
Ive selected a crater in edit mode and created a new object from this selection, applied subsurf on the new section then rejoined it to the main asteroid so that texturing looks right. But now im left with a messy join where the subsurfed section touches the normal asteroid.
I would subsurf the entire asteroid but this crashes my computer, the asteroid is already 90k vertices.
Ive tried selecting the offending area where subsurf and non subsurf meet and removing doubles but this doesnt help, ive tried recalculating normals- no luck. Also tried beauty fill. Also experimented subsurfing the whole crater as opposed to just the ridge, which helps a little!
Is there a way of gradating (is that even a word) subsurf so that at the top of my crater i have 100% subsurf and further towards the asteroid( further down one axis) theres less subsurf going on? Or perhaps im going about this completely the wrong way- this is the first proper thing ive modelled in Blender.
Hope someone can help
