Hey there I was reading this question (http://game-artist.net/forums/work-progress/14944-hard-edge-problem.html?textlink=&utm_source=newsletter&utm_medium=hot%2Bthreads&utm_term=14944&utm_content=textlink&utm_campaign=20101107) on game-artist.net and was wondering if there was a way to bevel or chamfer a vertex like how he is doing in Max (ie see his work through image here (http://img560.imageshack.us/img560/8176/vdfs.png)).

Thanks for your time.

Not at the moment - if you look at the screenshot titled "Chamfer verts" you'll see that it results in ngons (5-sided in this case) in the ex-quads around the windows. Until the bmesh project, which will add support for ngons among other things, is merged into trunk, Blenders chamfer/bevelling tools will remain primitive at best.

In the 2.4x version of Blender, there was a slightly hacky tool for bevelling but its not yet been re-implemented in 2.5 (at least when I last checked).

Its possible to build the same geometry as in the guide with a combination of face delete and sub-division but it's not as elegant as chamfer.

Ah ok that starts to make sense then, thanks CorsairX.

Ok so I've tried out your suggestion where I selected the 2 edges that join with the vertex to be beveled and subdivided them. Then I selected certain edges and deleted edges & faces. Then rebuilt the faces to this...

But I'm getting a slight pinched look....

how do I remove that so that it's nice and smooth?

Would you mind sharing the blend file through pastall? http://www.pasteall.org - it takes the guesswork out of duplicating the problem :)

'F' those 2 tri's to take out the pole. Thus making it a quad polygon. I see you want to make sharp edges. The only way I can think of besides edge weight is adding more edge loops around said hole.

Wont that make a slight ridge horizontally and vertically across the dome?
