    Normals problems

    I don't know if 3D Coat has a tool for this (it probably does) but for re-orienting all faces coherently you can use Meshlab instead of Blender if you feel you need to do this outside of 3D Coat. I think you might find it easier than Blender. Just install, import the mesh (File => Import Mesh) then go to Filters => Normals, Curvatures and Orientation and go to 'Re-Orient all faces coherently'. Then go to File => Export Mesh As to export your mesh with proper face orientation. Please note that Meshlab will muck up your smoothing groups / merge/average all of your vertex normals because it doesn't understand multiple normals per vertex so you may need to redo your selective normal smoothing or smoothing groups after exporting the mesh back out. If you want to do normal smoothing by angle outside of 3D coat you can use Wings 3D for that. It has an autosmooth feature where you can select the angle for an edge to be considered a crease or hard edge so vertex normals are not smoothed over it. That's what I used for this model : https://drive.google.com/open?id=0BwJaCsyXIqEedjNsajduUU83R3M After importing the model in Wings 3D toggle the body selection mode by clicking the red cube near the middle-top of the window then select the mesh, right click and select Auto-Smooth. To be able to specify the crease angle click the rectangle to the right of 'Auto-Smooth' in the context menu, enter the crease angle then press ok and export your mesh.

    3D Coat feature set inquiries

    Hey, Timmy. Thank you for looking into and addressing my inquiries. Since opening this thread I found : https://youtu.be/uU69uLo-kq0?t=3m15s and it seems that both feature 1. and 1.b are present in the 'Sharp Seams' and the 'To Planar' tools. Thanks for the suggestion I'll put off trying the demo until I've saved up enough to buy the pro version if I like it. Though I'm pretty sure now it's got everything I'm looking for and I will. Thanks a lot. Laurențiu.
  3. Hello, everyone. Thank you for your time. I'm not yet a 3D coat user but I do have a few questions about its features before I commit and become one and I would like to hear from people who are already using it on whether it provides some of key features I'm looking for. 1. Does it provide automatic splitting of the mesh mapping on the texture along the edges on the mesh which have faces meeting at an angle greater than a given value so that you don't have to manually define texture seams on the mesh? 1.b. Can you constrain the automatic UV mapping with regard to the amount of distortion which is acceptable so that it automatically creates seams to minimise distortion? 1.c. Can you have it automatically create seams between faces which, although not strictly adjacent are near one another, according to the incidence angle of their respective planes so it automatically splits the mesh mapping on the texture along mesh edges which are filleted or chamfered in actual geometry on the mesh? 2. When working with mesh normals, can you have it not try to average normals between faces which have an intersection angle of more than a given angle? 3. Can you have it smooth triangular meshes by creating additional vertices and triangles to soften the transition of the mesh surface between two adjacent faces whose meet angle is less than a given value? 4. Can it convert triangle only meshes to quad dominant meshes reliably and effectively so that a mesh which was originally triangles only becomes quad-dominant and the conversion is good enough to be subdividable without meaningfully altering the shape of the model? 6. Does 3D Coat support .ptex? I would very much like to hear from anyone using 3D coat on any of the points listed above. Please let me know. Thank you for your time and consideration. Laurențiu.
