3ds max Smoothing groups problem

whiketan

I have a model I was working on and then 3ds max crashed. So now when i loaded it back up it looked fine, bu then I tried to export it for a game engine and it always reverts the smoothing groups back to the crash smoothing groups. the model and textures export just fine however. I was wondering if there was some way to fully remove all smoothing group settings without destroying the model or uvs, Because just changing the SGs or even getting rid of them does nothing.

I have now tried both of your advice and am still getting smoothing groups messed up.
There is some sort of underlying problem that I cant seem to find

What engine are you using?

It could be an import settings issue, not something wrong with the smoothing groups.

In Unity for example: whenever you import a mesh, unless you tell it otherwise it will generate its own normals and just ignore whatever you do in Max.

It is the SC2 art tools exporter for 3ds max 2011 64 bit. There is no option pertaining to smoothing groups or vertex normals in the export options. I belive somehow my smoothing group infomation has become corrupt in some way. Is there any method to reset or repair them specifically?

screens might help

try resetting the xform

also can you edit your smoothing groups..do they change when you edit them in max...if not...pop an Edit Normal on to your object..reset... collapse...try again

Just tried X form, was ineffective. Smooth and edit normals modifiers have not solved problem either. Example of my problem:
smooothing in 3ds max:

smooothing when exported:

Please is there any way to repair the normals issues? This is really important

It looks like it's splitting the smoothing where there is a UV seam.

Can you post the model, maybe? People can get to the bottom of it faster if they can actually look at the problem.

I know this is like super old thread but I just run in a similar issue. So if you try to assign smoothing groups in max and nothing happens, then add editable poly modifier from the modifiers stack and collapse all. This will reset the smoothing groups and you will be able to edit them properply.

I found the answer from here >
