amycarlevaris Posted January 26, 2014 Share Posted January 26, 2014 Hi, I'm new here! I've been reading this site for a while but only decided to join recently. Wondering if I could get some advice on a strange issue I just started having. After my last save I must have pressed a key or made an inadvertent switch somewhere, because I'm just now having viewport issues (see attached photo). None of the objects in my model are transparent, however, they're appearing so in my viewport. There's also odd shading and pixelation. It doesn't matter whether I'm in orthographic or perspective view, shaded or realistic. It can't be a material issue, because up until my last save all the materials were showing up as they should. And it renders out just fine, no strange shading/transparency issue. I feel like it has to be a simple error that I just can't figure out! Thanks a lot for any advice (also, I'm using 3ds Max 2014).

jasonstewart Posted January 27, 2014 Share Posted January 27, 2014 Alt-X switches to "xray mode" you can select them and hit that to see if it helps. What objects are we talking about just the sidewalk? The backs of the "buildings" look like the verts got selected and welded in a strange way that the geometry is wrong to me but IDK what they are supposed to be like.

amycarlevaris Posted January 27, 2014 Author Share Posted January 27, 2014 Thanks for the reply Jason. Unfortunately Alt-X doesn't change anything in my viewport. Attached is a screenshot from a previous version of the scene - all the geometry is the same, just something different with the viewport. Link to comment Share on other sites More sharing options...
jasonstewart Posted January 27, 2014 Share Posted January 27, 2014 Hmm, can you isolate one of the offending objects and screenshot it with edged faces on? It really looks like a geometry issue. Link to comment Share on other sites More sharing options...
amycarlevaris Posted January 27, 2014 Author Share Posted January 27, 2014 It's attached.. though its hard to see the edges faces with this transparency/shading problem Link to comment Share on other sites More sharing options...
jasonstewart Posted January 27, 2014 Share Posted January 27, 2014 Oh wow, that is very strange. I have never seen that before, sorry cant be of much help I guess. Link to comment Share on other sites More sharing options...

Francisco Penaloza Posted January 27, 2014 Share Posted January 27, 2014 check the little box that is under your time line "degradation" I think is called, that one sometime help to improve video performance, also check the back face culling in your viewport options, it seems like double geometry or max showing both faces at the same time.

amycarlevaris Posted January 28, 2014 Author Share Posted January 28, 2014 Thanks for the response Francisco. I checked and unchecked the adaptive degradation box and checked back face culling on the objects, but neither changed anything. It's such an odd problem, I'm all out of ideas except for reverting back to the old file! Link to comment Share on other sites More sharing options...
Chris MacDonald Posted January 28, 2014 Share Posted January 28, 2014 I've had this problem before, and still to this day not managed to find a solution. I had to revert back to a previous file - even merging the current file into a new one brought the problem along with it. Link to comment Share on other sites More sharing options...

jasonstewart Posted January 30, 2014 Share Posted January 30, 2014 You can try a reset xform sometimes that fixes strange stuff like this. Link to comment Share on other sites More sharing options...
Guest dialog Posted January 30, 2014 Share Posted January 30, 2014 Try using viewport clipping...we faced many issues like this on our old workstation. Viewport clipping fixed most of the issues with performance (there are some downsides) but %99 of the time was the fix we used. Link to comment Share on other sites More sharing options...
amycarlevaris Posted January 31, 2014 Author Share Posted January 31, 2014 Desmond- good tip! I tried it, it fixed the main problem but created some news ones, but now at least the file is workable. Thanks!! Link to comment Share on other sites More sharing options...
marius e Posted January 31, 2014 Share Posted January 31, 2014 I have had this before.....and it might be the same problem. If your units is set to a smaller unit this happens, try a bigger unit size, that fixed my problem. Link to comment Share on other sites More sharing options...
Josef Wienerroither Posted February 2, 2014 Share Posted February 2, 2014 Might be the usual "Shaded" mode display problems with "Realistic Materials" in viewport setting. Select "Materials->Shaded with Maps" in your viewport or in the Views menu ( "Show Materials in viewport as" there ) Might fix it Link to comment Share on other sites More sharing options...
amycarlevaris Posted February 2, 2014 Author Share Posted February 2, 2014 Great tips guys, thanks. So far these tricks haven't fixed the problem, but I'll keep playing! Link to comment Share on other sites More sharing options...
