isaac_cm Posted April 1, 2009 Share Posted April 1, 2009 Hello, When I was chamfer my polgon I found a dark face , although I make sure that all vertices are welded still the face appear darker than the rest of the faces, is this normal ? thanks Link to comment Share on other sites More sharing options...
Horhe Posted April 1, 2009 Share Posted April 1, 2009 Select the face and click on 'flip normals'. Link to comment Share on other sites More sharing options...
isaac_cm Posted April 1, 2009 Author Share Posted April 1, 2009 it is not flipped to flip it again. I need it that way and even if I flipped it it become totally black. Link to comment Share on other sites More sharing options...
rmccoy Posted April 1, 2009 Share Posted April 1, 2009 it could be your smoothing groups that are causing issues Link to comment Share on other sites More sharing options...
isaac_cm Posted April 1, 2009 Author Share Posted April 1, 2009 no I did not apply smooth yet, just chamfer !! the polygon is attached please take a look. thanks Link to comment Share on other sites More sharing options...
LukeC Posted April 2, 2009 Share Posted April 2, 2009 Just as a test for smoothing groups you could try clearing all as a means of process of elimation. Are you sure its not just scene shading? is there issues when it is rendered? Link to comment Share on other sites More sharing options...
isaac_cm Posted April 2, 2009 Author Share Posted April 2, 2009 I dont know what you mean by scene shading but when I render the scene this face appear darker too, I collapsed the vertices at the end and now it look normal , but I did not know what possible cause this !!

SandmanNinja Posted April 3, 2009 Share Posted April 3, 2009 ok - I click "Select by Element" and get quite a bit of mesh errors. If this model was originally a single object, something terrible has happened to it. Link to comment Share on other sites More sharing options...
jinsley Posted April 3, 2009 Share Posted April 3, 2009 ok - I click "Select by Element" and get quite a bit of mesh errors.

isaac_cm Posted April 3, 2009 Author Share Posted April 3, 2009 experts did not know, newbie like me wont either ! but may be it is the export!! attached an fbx format. Link to comment Share on other sites More sharing options...
Gus_Rayvus Posted April 3, 2009 Share Posted April 3, 2009 I can not get you FXB into max and I don't have any idea were to start on the 3ds (seriously f-ed up). But I think you problem is an accidental co-planer issue. Grab those 4 vertices and move them along the dark edge polys, just past the next set of verts on their same edge and that should fix your problem.

isaac_cm Posted April 3, 2009 Author Share Posted April 3, 2009 (edited) could you explain more what is co-planer issue so I dont do that again (newbie here). please also take a look at that new polygon (max 2009 format) along with a rendered image I keep getting strange faces.

John Dollus Posted April 3, 2009 Share Posted April 3, 2009 (edited) coplanar is when you have duplicate polys on top of each other. To find out, select the single poly (not a window or a crossing selection) and delete it. If there's still one there, then it was coplanar. I got your FBX imported - coplanar isn't the issue but something's very odd. how did you create this? Box modeling as a start and keep collapsing the edit poly modifiers? Can you attach the max file instead of 3d or fbx? Edited April 3, 2009 by John Dollus Link to comment Share on other sites More sharing options...
isaac_cm Posted April 3, 2009 Author Share Posted April 3, 2009 yes of course the max file is attached in previous post, and it is modeled using a box and I only used edit poly then symmetry in the stack nothing else !! many thanks Link to comment Share on other sites More sharing options...
John Dollus Posted April 3, 2009 Share Posted April 3, 2009 Looks like all of the polys you highlighted are a bit warped so the crease is forced. Link to comment Share on other sites More sharing options...
isaac_cm Posted April 4, 2009 Author Share Posted April 4, 2009 any recommendation to fix this ? Link to comment Share on other sites More sharing options...
John Dollus Posted April 4, 2009 Share Posted April 4, 2009 Well, first of all, there are far more qualified poly modelers than me but here is what I would suggest: 1. you could select each offending poly and tesselate so that the warp transitions across more than 1 poly which will smooth it out but that's not really fixing the problem - just increases detail in the model to hide the problem. 2. You could start modeling the piece again. This time, try maintaining a history by adding Edit Poly modifiers when you change the topology though. That way, if it happens again, you can backtrack your steps and correct it without having to redo everything. You can even rename each edit poly step as a reminder of what it does. This will require some practice to get used to as going back and forth in the modifier stack can cause interesting results if you aren't careful. It may seem frustrating but it will make you a better modeler. When the model is finished, you can collapse the stack down to a single edit poly modifier if you want though it's usually good to keep an editable version as well.

ama Posted April 5, 2009 Share Posted April 5, 2009 Looks like you have some unwelded verts? Try welding them. Link to comment Share on other sites More sharing options...
isaac_cm Posted April 5, 2009 Author Share Posted April 5, 2009 thanks but I did!, I select all then I use auto weld so I dont miss any thing I also recheck problems vertices again to make sure they are welded. Link to comment Share on other sites More sharing options...
