Utility request: Softimage plugins

The triangle rule applies to both the formats and the game engine as far as I know, carcass wont compile a dotXSI to GLM unless it's in tris.

@@DT85: please ensure that the UVs are correct on the model

note that positioning is fucked up, as i mentioned this is due to me not parsing the animation yet

the UVs ought to be correct however

 

 

 

 

this is the top of the table, occluded by what looks to be one of the legs of the table

If the UVs don't match please post a picture of what the top of the table should look like

[DT.]

Table top UV's look spot on. Would a non-animated model help?

[ChalklYne]

Hey @@DT85... how would we export an animated fbx for md3 conversion then if the anims got working on this? Is it something we would just have to change in the fbx export options?

[eezstreet]

@@DT85 yes probably. a better idea would be your first person hands in FBX format, non animated, single frame as they have very defined texture areas on them and that makes it easy to detect glitches in the UVs if they exist

however I also found a good model for testing purposes. It's tris/quads combination, not sure if that's responsible for texture fuckery on it but I NEEDED TO DELIVER A MESSAGE DAMN IT

 

 

 

 

and it only took 4k verts to find the proper receptacle!?

[DT.]

Here's the fists:

No animation exported in the FBX options. Should look like this:

When this is up and running, I'm sure @@minilogoguy18 will be able to help you out. I can only help you so much from a 3ds Max point of view.

[eezstreet]

oh..

 

 

 

 

..i-i can fix it

[eezstreet]

Just found out that I have to incorporate a vertex transformation element and an entirely different approach to UVs...good job Autodesk, you're really great at documenting stuff (and "trianglating," whatever that means)

[eezstreet]

I've fixed the positioning of the fists, but the UVs are still messed up and I'm not sure why.

 

 

 

 

I really can't do much more with this until someone more knowledgeable like @@Xycaleth or @@mrwonko can take a look at it. I've also encountered an issue where MD3View will sometimes completely fail to export a MD3, causing it to write to the hard drive over and over until the hard drive runs out of space (!) and the program crashes. I'll examine that in a little bit.

I would like to merge MD3View into ModView at some point, and make ModView capable of exporting FBX, MD3, and GLM.

In the meantime, I'll be putting the code up on GitHub and working on some other projects until I can get this figured out.

That can be used for SO much evil XD

I don't know how exactly I can be of more help, I don't think an FBX from Softimage would be that much different than 3ds Max.

 

I don't really have anything on this laptop, out of town for the week.

 

Merging ModView and Md3View into one program sounds like a pretty good idea but maybe after the FBX importing issues are solved first since ModView would probably need a lot of work to be able to process things like vertex animations.

[DT.]

Confirmed with noesis that the FBX I sent to eez looks as it should, just to rule out something on my end.

[Archangel35757]

Do the texture UV coordinates need to undergo a coordinate transformation?

[eezstreet]

Not sure. I tried using the global transformation and it only made things worse. Using the global transformation on the vertices however resulted in the positions being correct.

[eezstreet]

@@Xycaleth: did you ever figure out what was wrong with the UVs?

[Xycaleth]

Nope. The code looked okay to me. Have you tried printing the values out to see if you get same values? They should be in the 0-1 range.

[minilogoguy18]

I'm no coder but could it perhaps have something to do with vertex ordering being screwed up from using an imported model? Usually after the models are imported from GLM the edges are split along UV boundaries, maybe welding those edges up then re-exporting will provide a fix?

[DT.]

@@eezstreet

 

Found the issue with this. It requires every model to be split along the UVW seam edges, probably something to do with rendering MD3's as the MD3 format makes these splits and the FBX format doesn't.

 

Also, can you please change it from Z axis up to Y axis up?

That's not something I can really fix unfortunately, I assume that's not a big deal for modellers?

 

Also, Z axis up is an OpenGL thing, Y axis being up is a DirectX thing. Won't change.

[minilogoguy18]

So we'll have to rotate all our models before export?

[eezstreet]

I thought he was referring to the view. I'm not exactly an expert on 3D math of that sort () so I'd rather leave that up to someone more experienced in the area.

[minilogoguy18]

It's not just that axis either, seems that in OpenGL -Y is front where of course we all know +Z normally is so that's 2 axis' that need to be changed.

[DT.]

Y- as the front matches up with Max's front view. When I export a Y up axis FBX, Y- becomes Z+. Because Max users have the option to export either Y or Z up, would be better to have FBX loaded as Y up. You'll probably have to do an axis conversion when creating a MD3 from an FBX though.

[minilogoguy18]

Yeah, would be best if md3view by defualt when reading a fbx file would do the conversion so that it loads with +Z up and -Y forward then it will let you export to md3 or glm without needing to manually rotate.
