Need help with 3ds max smoothing and crashing on export

LonelyBacon

So i've ripped a car model from csr racing 2 and the program that exports the model, exports as .fbx. I import the .fbx into 3ds max and the model looks perfect. When I go to export as .obj it crashes. But when I edit as poly the model's smooth mesh surface turns low poly with no smooth surface. Yes its already low poly but the surface becomes unsmooth. I try to make it smooth again but theres no way it will let me get it as smooth and perfect without normals issues. After doing all of that it lets me export fine. But its just messy. Ive tried to edit normals and reset the normals but it gets unsmooth again and if I add a smooth modifier it looks horrifying. Any ideas?

First example has no modifiers - https://gyazo.com/1489f1ab4442e06179dabec5ac55d998
Second example with edit poly - https://gyazo.com/2a726b81a4264170542676036829db26

It was more than likely had its normals edited in another program, or possibly max, but as soon as you add a edit poly modifier, max will bust all the normals.
Try add an edit normal modifier on top, and break all normals, collapse all to an editable poly and try redo smoothing groups.
Additionally, export and reimport as an obj.

Didn't work unfortunately , ill upload the file if any one wants to give it a try. - https://mega.nz/#!j4RHxYIQ!f_lmjThey5iwNeiinUOaRrGaibml-u_G-a_Xk2ly1eA

It could also be breaking the vertices into duplicates where there are hard edges? Try selecting all vertices and welding with a low tolerance.

Ill give that a shot when I get back home. Can I even weld vertices without having a modifier?

Of course, it's in vertex sub-object mode of editable poly/edit poly modifier.

Tried that but no luck , maybe its an issue with the exported fbx file that the previous program exported.

I know sometimes I get fbx files from Blender that refuse to load in Max, and vice versa too.

But you can load the file in Max.

I would suggest you enable Backface Culling, Reset Xforms, Collapse, use Edit Normals to reset the vertex normals, use Editable Poly to remove floating vertices, and remove unused UV vertices. You can also use Xview to check the model.

Okay so I've got somewhere but still curious to why it doesn't stay perfect when going to poly mode. I'm still trying to fix small details. I wonder if there is a way to rebuild the mesh as one so that all those isolated polygons and overlapped faces will disappear.

Editable Poly doesn't support certain topologies. For example a fin extruded from an edge in the middle of a surface. That fin can't be welded to the surface, the vertices have to be detached.

Editable mesh however does support that. Trouble is, Editable Mesh allows you to really fuck up your model if you're not careful. It also lacks the nice newer modeling tools in Editable Poly.

Yeah pretty much anything I do to modify the mesh just shits on it. I'm gonna check the export tools I used before hand to see what version they support. I'm gonna try an older version of csr racing. Thanks for the help guys!
