detbear Posted September 2, 2015 Posted September 2, 2015 I don't know about you guys, but I'm really struggling to repair normals when they appear like this on the screen. V 18 is what I'm in. ALSO....A great feature request would be to have an option to color the patches "red" or "blue" depending on what direction. Then have an option to "flip all red" or "Flip all blue" THAT WOULD BE GOLDEN Quote
Hash Fellow robcat2075 Posted September 3, 2015 Hash Fellow Posted September 3, 2015 Normals are in the middle of a patch. Those look like something else. Quote
itsjustme Posted September 3, 2015 Posted September 3, 2015 There was some realtime normal indicator strangeness in v18.0L that happened for me when a part of the model was hidden. That problem was fixed in v18.0m, but maybe this is a variation on that. The report is here: http://www.hash.com/reports/view.php?id=6612 Hope that helps. Quote
detbear Posted September 3, 2015 Author Posted September 3, 2015 RobCat..... I know it looks different than a normal, but as crazy as it appears....that's actually what it is. David..... I looked at my version of 18 and in fact I am on 18L. So this could indeed be the issue. Thanks for you guys input. I need to upgrade, but that's tough in the middle of a project. I may port it back into V17 to flip things. Is there a better solution to fixing normals. I find that while Steffen's plug-in does help some places, it creates other undesireble "flips" than were correct originally. Thanks, Kevin Quote
John Bigboote Posted September 3, 2015 Posted September 3, 2015 No other way that I know of other than the tried and true... turn on normals, eyeball model for wrong facers, use the patch selection tool in conjunction with shift to select multiples... F key to flip... Your feature request sounds great with the red and green, however... the essence of a normal is that the program really does not know which side of the patch to point to as 'forward', therefore it could never discern which patches you are referring to to flip when you say 'flip all red'... all patches have red on ONE side of them... so all patches would flip. No? Quote
detbear Posted September 3, 2015 Author Posted September 3, 2015 Matt, I'm not familiar with the nuts and bolts of the programing, but it could be you are correct. I think the hardest thing is fishing through all the little yellow lines. It's so hard to see in many cases. BUT if you had an option like "Show normals as color patches", one could easily pick out the ones that had the odd color. The speckles or groups of speckles.... If the software can have patches one way or the other(And it obviously does)....I figured there may be some way to color the patches according to the direction they're facing. Who knows? Quote
John Bigboote Posted September 3, 2015 Posted September 3, 2015 That would be a useful feature... a better 'identifier' to see what is facing in or out... Quote
Fuchur Posted September 3, 2015 Posted September 3, 2015 And what is "in" and what is "out"? That is very hard to define for a software, if the object is not waterproove. I had an idea before about this, involving a "light-like" emitter of rays which a person can put into a object and everywhere where the rays hit a surface (and bounce off again and again like photons/radiosity would do) the normals would face away of the hitzone there... but till now it is only a feature request and I am not sure if it would work in every situation. See you *Fuchur* Quote
Hash Fellow robcat2075 Posted September 3, 2015 Hash Fellow Posted September 3, 2015 The better identifier for seeing ab-normal patches is to toggle Backface Culling (Shift 6) and view in shaded mode. Inside-out normals are pretty obvious then. >Refind Normals does a pretty good job of getting all normals in the same direction Quote
detbear Posted September 4, 2015 Author Posted September 4, 2015 Do you mean the "Correct Normals" function. If so, that crashes A:M everytime for me. Especially since it is a more complex model I guess. Quote
Hash Fellow robcat2075 Posted September 4, 2015 Hash Fellow Posted September 4, 2015 If I in the model window with nothing selected there is a menu choice for "Refind Normals" I'm not sure what the intended difference between "Correct Normals" and "Refind Normals" is. A model that crashes "Correct Normals" would be a good candidate for a bug report. Quote
Hash Fellow robcat2075 Posted September 4, 2015 Hash Fellow Posted September 4, 2015 I'm trying both "Correct Normals" and "Refind Normals" on a simple case. "Refind Normals" seems to try to get all the normals to be facing one way. "Correct Normals" may be for some other purpose? Quote
detbear Posted September 7, 2015 Author Posted September 7, 2015 In both Cases..... with either tool, it results in a real jumble of a mess. Better off doing it by hand which is a really miserable task. Well maybe if I were working with some low patch model like Tom or a square box it may work. Quote
