Exclamation Convert to Editable Poly PROBLEM

Hi, I have just created an account here since I couldn't find a solution to my problem, so here it is. I am working on a model right now and everything was fine until it somehow got corrupted and started crashing with a lot of things I did -NURMS subdivision, even using the Loop tool with edges- so I decided to just export what I had in a new file in hopes it would work itself out. The problem is, when I try to convert the imported mesh to edit poly, some polygons get weird and don't get lit well, they generally dont mesh with the rest of the model. Here are some pictures of it.

Here is the model in editable mesh when I just imported it

And here is the model when I convert to editable poly

I tried almost everything...I mean I'm not a pro so I'm kinda stuck here , the polys are not flipped, I tried that, I also tried recreating them but they stay busted.

Also, even when I apply a smoothing group, all the model stays jagged

If anyone could find a solution to my problem (or the first one where it crashed for reasons unknown) I would very much appreciate it.

ps: Sorry if there is already a thread to this problem, didn't find one, wasn't too sure of what to search for.

Try merging the file into a new max file and see if that works.
Make a new blank max file then go to merge and merge in your corrupted file.
This sometimes works.

Good luck

Try adding an Edit Normals modifier, select all the normals and reset and see if it fixes it.

Try to export it as .obj, then import it in to a freshly reset 3ds max scene

All else fails, grab all the faces and do a detach to object. That will usually clean out any bugs. Just be sure to delete the empty node that was left.

Turn to Poly modifer + collapsing stack usually fixes this kind of errors.

Looks like some of the polys have ended up facing the wrong way. That's not legal geometry in editable poly mode (if they're welded) and can cause crashing and all sorts of nastiness when converting.

As darthviper107 says, resetting the normals should sort it out.

Or worse, you might have duplicated and flipped polys on top of each other. Back to back. That can be bad too and can be harder to fix. Try selecting and moving the polys and see if they come away, or are only attached by some verts. The Xview option under the viewport label menu might help find them if that's the case.

I'd recommend turning the default viewport lighting to 1 light so you can see which way the polys are facing while working and ideally turn on back face culling so they're invisible if facing away from the viewport. That makes it much more obvious if you're doing something like this.

xview is your friend

Xview is a bit hit and miss IMO. It often highlights things that aren't errors. It mis-identifies the corner verts of cubes as T-Verts when they aren't what I'd say were T-verts. And doesn't actually have options for some things that would be really useful (like back to back polys). it certainly can help. But it's not great in all cases.

It does have an option for face orientation though, so it might help here.
