I'll make Mario, if you want.

I think I've figured out a lot of the animation data, though I'm still not too sure on everything. I've mainly looked at fighter data (a small subset of it), other model types might have additional data that I haven't looked at yet.

Header:
char magic[4] - "OMO "
uint16 unknown[2]
uint32 unknown
uint16 unknown
uint16 channelCount
uint16 frameCount
uint16 frameSize
uint32 channelTableOffset
uint32 fixedDataOffset
uint32 frameDataOffset

Channel Table Entries:
uint32 animType
uint32 boneId     // matches id in vbn (2 bytes after bone parent index in vbn)
uint32 offsetInFixedData
uint32 offsetInFrame

Fixed data size and frame data size for a channel is determined by it's animType - can be empty

Types:
Constant - 1x Vector3f (constant on all frames, no frame data)
Interpolated - 2x Vector3f (frame has interpolation value for each coordinate)
There are others I haven't figured out

Frame Data:
buffer frameData[frameCount][frameSize]
Channel frame data starts at: frameData[frameNum] + frameDataOffset
Seems to be uint16 interpolation values (i.e. 0x0000-0xffff for 0.0 - 1.0)

Eyeballing translation and scale values looks based on this looks sane, I'm not sure about rotation.

animType bit field guesses:
0x04000000 - has scale
0x02000000 - has rotation
0x01000000 - has translation
0x00200000 - translation constant
0x00080000 - translation interpolated
0x00007000 - rotation constant
0x00005000 - rotation interpolated
0x00000200 - scale constant
0x00000080 - scale interpolated

... nice to see some1 else research the omo format besides me.. even tho i dont understand hex much.. gratz to u!

altho i was looking more into stage animation files... and only falcon

[uac9000]

How do you guys prefer to set up your model textures in 3d studio? I put in specular, diffuse, and normal maps, but is it necessary to use displacement or self illumination maps? Also what kind of lighting do you recommend for rendering textures, like skylights or mental ray lights?

[supersmashball]

The question I never got the answer to was, how do you EVEN do that? Kinda new to this stuff.

Are you referring to my question?

[supersmashball]

Kind of...
All I can do is apply the normals.

Oh, well i learned everything i know from these videos https://www.youtube.com/watch?v=Xi467BO_-JY    https://www.youtube.com/watch?v=F-e43rUcF8I

Great, saving them for later...
My headphones are gone. I'll watch them at night, maybe.

THIS. I'd would like to know the answer too. But wait, does SSB4 use self illumination maps? Because I haven't seen any of them in any fighters' textures...

[Demonslayerx8]

I believe they do.. which is built inside their normal maps under the Red and Green channels... Blue channel has pretty much nothing, while the Alpha is the spec map

[MarioSonicU]

which trophy do u want from Smash3ds? cause i can get those exported easily.

Well here are the trophies I want from the 3DS version -

- Tanooki Mario and Kitsune Luigi
- Statue Mario
- All of the Fighters' trophies and alts (Except for DLC)
- and Epona

By the way can you also export the actual fighters too?

smash3ds fighters (and some stage models) have their objects stored in .mbn files, while the skeleton and textures r in the .bch file, and those I can't get opened with Ohana, so currently, no cant get fighters.


i'll send you the files shortly

OK, I see. But how could I convert those channels into actual self-illumination? I mean...normal maps don't display self-illumination, afaik, so how could I display self-illumination (using the normal maps) in 3DS Max/Blender? Sorry if the question is a bit confusing...
