Genzel Posted June 17, 2011 Share Posted June 17, 2011 I'm working on an object, and all of it's face normals are locked along the Y axis. This problem is specific to just the one object, new objects or new files are completely fine. Extruding along the normal is the same as extruding along the Y, and the draw normals option shows all the lines pointing one way. Faces with normals that are at X/Z or almost at X/Z have very short or non-existent normals. If I make a new mesh with new geometry, the problem does not appear. If I copy the geometry into a new object, the problem persists. If I add mesh to the old object, the problem translates to the new mesh. Here is a picture of the problem on a spherical shape which should have normals in pretty much every direction: http://thumbnails35.imagebam.com/13700/87ef35136999350.jpg Link to comment Share on other sites More sharing options...
greywaste Posted June 17, 2011 Share Posted June 17, 2011 Hmm, I've had this happen too in 3ds max, but I can't remember if it was actually some sort of viewport bug (and it was fine upon re-opening the save after restarting max) or if it was a smoothing/geometry problem. I hope someone can help you anyway. Link to comment Share on other sites More sharing options...
Ghogiel Posted June 18, 2011 Share Posted June 18, 2011 Have you tried to recalculate normals? ctrl+n in edit mode. Link to comment Share on other sites More sharing options...
Genzel Posted June 18, 2011 Author Share Posted June 18, 2011 Yeah, that's when I noticed the problem. The normals are all in the proper direction in relation to the other faces, but they are stuck in one axis. Link to comment Share on other sites More sharing options...
Ghogiel Posted June 18, 2011 Share Posted June 18, 2011 (edited) Does blender have an actual edit normals modifier, one where you can grab normals, move them, or relax them? Edited June 18, 2011 by Ghogiel Link to comment Share on other sites More sharing options...
Genzel Posted June 18, 2011 Author Share Posted June 18, 2011 I've never seen a way to do that, no. I looked up what I could about normals in blender, and I've found nothing about this problem. Link to comment Share on other sites More sharing options...
Ghogiel Posted June 18, 2011 Share Posted June 18, 2011 try exporting it as an obj and reimport it Link to comment Share on other sites More sharing options...
Genzel Posted June 18, 2011 Author Share Posted June 18, 2011 That fixes it; I still don't know what the problem was though. I noticed that it was really messing with the UV unwrap function. Unwrapping cylinders was giving some bizarre results, but it's UV mapping fine now. Link to comment Share on other sites More sharing options...
LHammonds Posted June 20, 2011 Share Posted June 20, 2011 I have not run into that problem either for Blender. If you post the non-working file, I'll take a look at it and see if I can spot something out of the ordinary. Link to comment Share on other sites More sharing options...
