AJLynn Posted July 10, 2007 Share Posted July 10, 2007 mental ray is getting all funky on me, and I figure I must have some duplicate faces but it would take forever to get this cleaned up the old fashioned way. Does anybody have a fast way to find and/or fix duplicate faces? Link to comment Share on other sites More sharing options...
Ricardo Eloy Posted July 10, 2007 Share Posted July 10, 2007 Nope... and I'm gonna follow this one, because I could really use the info. Link to comment Share on other sites More sharing options...
Claudio Branch Posted July 10, 2007 Share Posted July 10, 2007 ...it would take forever to get this cleaned up the old fashioned way. I'm not sure what you have tried in the past, but when I had this problem, I would render out the scene with the portion of geometry that was problematic and locate duplicated faces pretty quickly. If you use a procedural texture on geometry with duplicating faces and render with MR it is nearly impossible to miss them... Link to comment Share on other sites More sharing options...
STRAT Posted July 10, 2007 Share Posted July 10, 2007 personally, i'd learn to model properly. Link to comment Share on other sites More sharing options...
hughie Posted July 10, 2007 Share Posted July 10, 2007 you could use STL Check to find them but they will still be a pain to fix. Link to comment Share on other sites More sharing options...

molson Posted July 10, 2007 Share Posted July 10, 2007 If you weld all the verts you should get rid of all of the coplanar faces that share vertex positions. Link to comment Share on other sites More sharing options...

Sawyer Posted July 10, 2007 Share Posted July 10, 2007 I am wondering if this is a universal problem with all programs? I have lost jobs because of the time it took me to deal with this with ADT files. The archi would rather do something in house in acad rather than pay me to remodel everything. I would probably buy another software it it had a good work around. Link to comment Share on other sites More sharing options...
jvlive Posted July 10, 2007 Share Posted July 10, 2007 what happens if the verts aren't in the same position? ...or aren't in the same object at all? interesting thread. by "modelling properly" do you guys mean to collapse the whole scene to a single object? i'm a pretty bad modeller.

STRAT Posted July 10, 2007 Share Posted July 10, 2007 by "modelling properly" do you guys mean to collapse the whole scene to a single object? i'm a pretty bad modeller. modelling properly means a nice clean mesh. no overlaps, double facing, rogue faces/verts, no 'eyeing things up' etc etc etc. nice and clinical. something you'd be proud to eat your dinner off. trouble is, some softwares (like sketchup) have a habit of giving unexplained problems to your mesh sometimes. or you might recieve a mesh you need to clean up from a client or collegue who cant model properly. whichever, it's a software wide problem, your fault or not, which is a pain in the butt.

Sawyer Posted July 10, 2007 Share Posted July 10, 2007 whichever, it's a software wide problem, your fault or not, which is a pain in the butt. But our buddies at acad have been telling everyone about these BS.. er..I mean BI models that are universal that will solve all their problems like Revit ADT and Sketchup. They are led to believe its a working 3d model that can be rendered but when we get them they look goofy as crap. But I have talked with clients who really believe their model is great and all I need to do is render it. They have been so convinced by adesk that their model is a 1 solution fits all type deal that they don't want me to remodel it and they think I am nuts that I can't render it correctly.

anthony cortez Posted July 10, 2007 Share Posted July 10, 2007 Haven't tried this out yet, but theres a 'DeleteDoubleFaces' Script on scriptspot.com that could do the job. http://www.scriptspot.com/bobo/mxs2/ddf/ddf4.zip Link to comment Share on other sites More sharing options...
AJLynn Posted July 10, 2007 Author Share Posted July 10, 2007 Anthony- Thanks, that script worked wonders. Strat- I'd love to be working with only nice clean models made in Max, but I can't - I don't do 3D full time, and there's not enough time for anything fancier than Sketchup, with all the design decisions that we're still making.

gfa2 Posted July 10, 2007 Share Posted July 10, 2007 In what way are coplanar faces giving you a problem? Is it dark spots with the GI calculation? I know your asking about MR, but in Vray that can be fixed by setting the secondary rays bias to 0.01 instead of 0. Maybe there is a similar setting in MR. Animations and coplanar faces is obviously a whole different matter because different materials will jump on top in different frames. This setting won't help that. Sounds like that script will though...that's a nice one. Link to comment Share on other sites More sharing options...
