Max Viewport looks "weird"

[clivengu]

Hi, I have been working on this architectural building (usually i do interior view)... then i start to have this weird -like polygon tearing apart - in my viewport when viewing from certain distance.. Is very disturbing...

 

May I know what could be the problem to this? I never have this kind of problem when im doing a smaller size scene (room etc).... Could it be lack of cpu memory, or it has to do with the CAD file im importing in? I try deleted the Cad Plan but is still the same.. Hope sm1 able to help me here. Thanks

That looks like co-planar polygons.

 

In other words, it looks like there are faces overlapping each other - Colliding geometry.

yeah there some overlapping over walls n floor, .. But even the FULL 1 BLOCK of the hotel (the center Block of d building i modeledl using just 1 box)... also showing that sign of "damaging polygon"

Try clicking one of the damaged faces. Then click the same spot again. Does it select some other face behind it?

 

Might be a video driver issue, but that's really strange.

 

You could also select by element and see if any faces are unselected. If so, then it's a face that belongs to another element/object.

omg! that looks wierd!

 

does it appears in the rendering? if yes, try to apply shell smooth or shell modifier. if not, maybe it has something to do with the graphic driver, you may want to use openGL, or Maxtreme if you are using nvidia.

 

Hope this helps. Goodluck!

i would imagine you have this model pretty far away from the origin 0,0,0 and your scene units are in something very small like 1 unit = 1 millimeter - both of which are fairly bad practices if at all avoidable.

 

IIRC to resolve this viewport trouble, you can turn on viewport clipping and pull your near distance (triangle in the bottom right of the viewport) up slightly to clip further forward.

Your imported model might be far away from max's 0,0 origin.

Select all of you geometry and move it to the origin point, should resolve matters.

 

Then again, it might be a video driver issue as pointed out by Joel.

matt is spot on, 90% of the time this sort of artifact is that.. Otherwise the scale can be off, or you could be using different world units than the model was built on.. (IE: Using Meters for units on a model built in inches can reduce the accuracy of the viewport to pretty much nothing.)

 

Otherwise check your welding, or look for stray objects out in the middle of nowhere.

I have had issues like this lately with models others have started. Often it is to late in the process to correct the problem properly, but if you work with a user view, and not a perspective view, the polygons will display normally.

Can I get the file? That would be for test this internally and figure out if we could improve this situation?

Many 'models' from clients are perfect to worki with as they follow correct workflows but as more often than not they are untidy files.

 

Make sure max system units are in cm, you can set display units to whatever you like. Then if need be, rescale any imported geometry to correct size (making sure you do it at sub-object level ie all verts / faces selected). Then make sure the centre of the scene is at world 0. This is all easily done by grouping it unless there are heirarchies and instances - then its a pain.

 

Max freaks out when stuff is miles from origin.
