I have just gotten to try the program, it actually does work on other models as well, but with the same issue as the AMR, it won't convert meshes with few faces like eyes for example.
yeah, the byte indices don't really fit, even when I switched to backface culling in a test.
Do you think you could link me the source so I can study it? C is the only programming language I actually understand on more than surface/basic level
Pmed you.

I feel completely stupid right now but I have no idea how to read a number stored in 4 bytes...
dunno.PNG
bs = NoeBitStream(data, NOE_BIGENDIAN)
bs.readUInt()

I cannot load anything in noesis yet in fact as I haven't been able to code anything yet ^^"
Here's a Noesis Python script for the format.

So I have rewritten my plugin based on the one provided by Bigchillghost, however I am having issues reading certain textures. Some work fine, but some, like normal maps and several ao and sphere maps do not, due to different pixel data sizes and compressions, for example this one(chr_comn_ran_face2.gtf from chr_head_rank_104_krn_a.pta). Could anyone take a look?

Could anyone help?
I suspect my bone rotation and scale data isn't right, but i dont really know how to fix that

very few people only can judge from a picture :D

Still freezing? See a suspisious NoeBone () line, where you shortened the params list.
(I know that's possible in C, in python, too? Just in case...)

params
noeBone = NoeBone(len(noeBones), boneName, boneMatrix, boneParentName, -1)

Tried, still the same. I shortened the param list because that's the root bone, with no parent(it doesn't even have a name), I saw some plugins with shortened param lists so i thought it might work this way xd

yeah, this line in the else: path of your bone loop makes it crash:
MTRX = ROT.toMat43()

Some ROT values are too big, I think:

Code: Select all

Detected file type: The iDOLM@STER One For All Model
PTR
32
60776
214
1 (0.0, 0.0, 0.0)
2 (0.0, 0.0, 0.0)
3 (0.0, 0.0, 0.0)
4 (0.0, 0.0, 0.0)
5 (0.0, -632378032652288.0, 0.0)
...
(Might be a matter of endianness?)

These are the bytes at 0xCB8 in the pmd, 3f c9 0f d8, that's big endian notation of a 32 bit float value.
Your script seems to switch Noesis to BigENDIAN but the output is -632378032652288.0?
(You usually get that value in case you read it as a little endian one.

(little endian (d8 0f c9 3f) would result in 1.570796, which seems to be a correct ROT value i.e. an angle in radians (180°).
But in the pmd it's big endian. :? )

Maybe better you read your matrices using POS = NoeVec3( (bs.readFloat(), bs.readFloat(), bs.readFloat()) )
for example.
Bones look funny, so you might need to recheck that:

PS3 games don't usually use LittleEndian, do they?
I've tried using floats, and it does not freeze anymore, no bones pop out either though :D

Seems like at very least scales are displayed correctly now, not so sure about positions and rotations(might as well be wrong order)

I've tried using floats, and it does not freeze anymore, no bones pop out either though :D
You need to add
mdl.setBones(boneList) before mdlList.append(mdl)

For the endianness thingie: I think readBytes(count) simply reads "byte by byte" no matter which endianness was chosen.

That's kind of weird, some bones are pretty much located where they are actually supposed to be, most of those are physical bones like neck/back/knee ribbons and skirt

Just checked again and some bones have their locations all mixed up
for example BASE bone is fine but MUNE1 is mixed up and so on

This is head, for some reason the face bones are on ground and oriented wrong, perhaps the locations arent just locations but offsets relative the parent bone: Image
