Hi Brian,

> It tests fine in Carrara!

Good news, thanks for testing it there!

I'm not sure if this will be better than OBJ for going into Carrara or not, it seemed like Carrara has a good OBJ importer so it may be no different but it is not bad to have choices!

Max on the other hand does not have a very good OBJ importer and they do not seem to be in much of a hurry to improve it, so that's why it should make a much bigger difference for Max.

Hi PaQ, thanks for testing in Max!

Yup, looks absolutely perfect - all n-gons and normals look totally intact and proper there, great!!!

Is there a way to turn on a display of face normals to see which direction they are pointing? Can you take a look at that and see if they are all pointing outwards as expected? That would just be nice to verify as well.

The only thing that is not quite perfect with FBX is that it seems that it doesn't have a structure that allows for a full welding because it doesn't look like 2 adjacent polygons can share the same 3d point but have a separate shading vertex normal for each face. But that would only be apparent if you started dragging vertices around, for rendering directly it does not make a difference. If you need to weld coincident points you can use Max's built in weld/merge vertices function for it anyway.

The kind of annoying thing is that this is actually all the same data as is already written to OBJ, there really isn't a good reason why they should not be reading in the OBJ data just as well as this... But anyway it will be nice to finally have a really good option for bringing data into Max with the high quality true vertex normal shading which makes such a significant difference.

I guess the only other thing left to see is if its n-gon handling is up to snuff for handling really complex n-gons or not. But judging from the initial result it may be good at it.

Hi PaQ - one more file to test here if you could, this one has just one big n-gon in it with 814 points, it should look like this:



It should be a pretty good test to see what kind of n-gon ability will be possible there.

In Carrara again so you can compare maybe.

That works fine for the 2 examples above!!!
Wings3D can save as fbx 5, fbx 6, and ascii fbx
What is your?

In the last version of 3DS Max (2009 & Design 2009) the OBJ importer is the previosly plugin by Guruware gw::ObjIO.
So now the Max importer is now so bad at all.
But FBX is a more modern standard and your work is highly appreciate.

Hi PaQ...

Can you share your setting when import fbx file to max ?
Maybe you can give me a screen capture of the import dialog window.

Thanks

Well I'm using the default settings, I didn't change anything. Just using the last version for my max version from autodesk.
Looks like it isn't working for you ?

If that works for Wings3D, seems that must be the same for 3Dmax ;)

So try Wings3D (it's free) and re export as FBX and now load this new FBX in 3DMAx ;)

Hi PaQ...

Looks we have different version of fbx importer.
You have the new one.

@pilou...

I will try it...

Here you can download the newer version of the FBX importer/exporter for free. It's necessary only a registration (but is not really necessary, at the end you will be redirect directly to the download page).

Hi Pilou,

That's good news too, because Wings had some difficulty reading in OBJ files also.

So it looks like this will also be the best way to move data into Wings as well as Max.


> What is your?

I think it's fbx 6, or 6.1 to be exact but that is compatible with 6.

Hi Anis, I think your version you were using was 3 years older than the latest importer. It looks like they have made a lot of improvements to n-gon handling since then.

Anyway that is good to know that you need to update to the latest FBX importer to get a good n-gon import.

As long as you have the newest importer plugin, this will definitely be the best way to transfer data into Max.

as far as I can tell it works really well in max 2009, but the max9 importer might be broken.

Thank you Michael.
