sygboe Posted February 12, 2008 Share Posted February 12, 2008 hi, i'm new to modelling in 3dsmax (trying to ditch sketchup) ive made a polyline. and extruded it with an extrude modifier. then added an edit poly modifier. i've got some faces that seem to have a black gradient on. i tried to flip and unify normals, but it's not that. so far i've been deleting the face and redrawing those bits. could anyone tell me what caused this please, and how best to fix it? here is a pic. thanks in advance Link to comment Share on other sites More sharing options...
Claudio Branch Posted February 12, 2008 Share Posted February 12, 2008 Those faces are probably turning out that way because the initial line work contains undwelded vertices. Make sure that you weld all of your vertices prior to adding any modifier or converting a spline to mesh/poly. However, you should be able to fix the problem by welding the vertices afterwards. As a last resort, delete those polys and recreate them. Link to comment Share on other sites More sharing options...

Ricardo Eloy Posted February 12, 2008 Share Posted February 12, 2008 Those vertices look welded to me. I believe this black weirdness is just a video glitch, nothing else. In max2008 I get those all the time and they turn out to be literally nothing. But, if you get the same look on rendering, then do as Claudio said: delete the funny ones then cap them.

mdviz Posted February 12, 2008 Share Posted February 12, 2008 It looks likes a smoothing group problem to me. Go to sub object, select all faces, "ClearAll" smoothing and re apply with "Autosmooth". This is a common problem with shape extrusions. Link to comment Share on other sites More sharing options...
AFK_Matrix Posted February 13, 2008 Share Posted February 13, 2008 Also check that your with your original polyline all of the vertex's are on the same plane. Ie if you have drawn it in the top view (plan view) then all of the vertex should have a value of 0 on the z axis. I sometimes find if I have vertex's that are not on the same plane and I extrude them I get that black look. Link to comment Share on other sites More sharing options...
WAcky Posted February 13, 2008 Share Posted February 13, 2008 I believe Michael has the correct answer. I would put money on it being a smoothing group issue. The faces are being smoothed by a little function that isnt really used too much. It has merit in modelling for video game assets but not really high detail stuff. Look up the help file for a bit of a lesson on it. It may come in handy one day. Link to comment Share on other sites More sharing options...
