Alright, change of info. The developer is currently proposing this: "* Core function (C) takes a mesh, scans it to detect edges marked as sharp, computes a normal for each vertex for each face accordingly, and stores those normals into a Loop CD layer. Note edges considered as sharp do not only include those marked as…
"I hardened that edge because that is where the uv seam is" There is absolutely zero reason to do that. You misunderstood why UVs need to be split at hard edges (to allow for texture padding in places of infinite change of normal directions = hard edges). The other way around (automatically putting hard edges at all the UV…
A vertex can only have one normal. Whenever auto-smooth wants to make a sharp edge, it duplicates a vert so you can have two different normals at the same point, making it look sharp (a crease in shading). If you want to "commit" this duplication so the sharp edges are permanently split for you to extrude them, use the…
Well it's not a great alternative, but you could increase the number of segments with the mousewheel, deselect the ones on the end with Alt+Shift+Selection mouse, and delete the edge loops in the middle with XG (Delete->Edge Loops). Or you could do two cuts and some edge slides, or do one cut at a time and just put it…
Any UV seam would double vertexes too, prevent tri-stripping, not only sharp edges. So performances wise there is no difference. Just not necessary to always make hard edge where UV seams are for nm baking
Thanks for the tips on sharp edges. I am now trying to write a script to get the perimeter edges of a face selection and then turn those into sharp edges. Executing the lines individually through the script editor seems to work alright, but for some reason when I put them into a custom operator, they dont give the same…
The Edge Flow addon doesn't seem to want to install for me in the official 2.8 release. Anyone know of a way to get it working? https://blenderartists.org/t/it-is-finally-here-edge-flow-set-flow-for-blender-benjamin-saunder/1128115
Snow : yes, but this would not select "implicit" hard edges (= the ones coming from the global Auto smooth angle). My goal was to be able to select *both* implicit and explicit hard edges in one operations, and RN's script does exactly that :)
