Maxscript Import non-matrix bones

I have trouble importing bones with XYZ(W) values.
I'm not really certain about the order of the coordinates.
Code: Select all
BoneCount = readlong f
fseek 0xC #seek_cur
for x = 1 to BoneCount do (
fseek 0x8 #seek_cur
BoneID = readlong f
BoneParent = readlong f
PosX = readfloat f
PosY = readfloat f
PosZ = readfloat f
PosW = readfloat f
RotX = readfloat f
RotY = readfloat f
RotZ = readfloat f
RotW = readfloat f
ScaleX = readfloat f
ScaleY = readfloat f
ScaleZ = readfloat f
ScaleW = readfloat f
fseek 0x10 #seek_cur
)

That's because it's a Transformation matrix and not Quats i belive, it would be so weird, in fact, you can't position with quaternions in 3DS MAX, it just doesn't make any sense.
Thsi is how i put 4x4 Transformation matrices on 3ds max:
Code: Select all
BoneCount = readlong f
fseek 0xC #seek_cur
for x = 1 to BoneCount do
(
fseek 0x8 #seek_cur
BoneID = readlong f
BoneParent = readlong f
trans1 = point3 (readfloat f) (readfloat f) (readfloat f)
readfloat f
trans2 = point3 (readfloat f) (readfloat f) (readfloat f)
readfloat f
trans3 = point3 (readfloat f) (readfloat f) (readfloat f)
readfloat f
trans4 = point3 (readfloat f) (readfloat f) (readfloat f)
readfloat f
Transformation = matrix3 trans1 trans2 trans3 trans4
fseek 0x10 #seek_cur
)
Works for me, not sure on your format though.
For making the bone you should do this:
Code: Select all
newBone = bonesys.createbone
newBone.transform = Transformation
If the result looks weird try adding this:
Code: Select all
newBone.transform *= newBone.parent.transform
I hope that works

Sadly it didn't.
This is the data for 1 bone. Importing it as a 4x4 matrix doesn't yield decent results, nor did your method.
The best result I got with this script:
Code: Select all
fseek f BoneStart #seek_set
if BoneCount != 0 do (
BNArr = #()
for i = 1 to BoneCount Do
(
fseek f 0x8 #seek_cur --skipping junk
BoneID = readlong f
BoneParentID = readlong f
print BoneParentID
rx = readfloat f; ry = readfloat f; rz = readfloat f; rw = readfloat f
px = readfloat f; py = readfloat f; pz = readfloat f
sx = readfloat f; sy = readfloat f; sz = readfloat f; sw = readfloat f
fseek f 0x14 #seek_cur --skipping offsets
BoneRot = (quat rx ry rz rw) as matrix3
BonePos = [px,py,pz]
BoneScl = [sx,sy,sz,sw]
bne = dummy showLinks:true showLinksOnly:true
bne.scale = BoneScl
bne.name = Bone_Data_array[i].BoneName
bne.rotation = BoneRot
bne.pos = BonePos
append BNArr bne
if (BoneParentID != -1) then (
bne.parent = BNArr[BoneParentID+1]
bne.transform *= bne.parent.transform
)
)
Print ("Bone data end @ 0x"+((bit.intAsHex(ftell f))as string))
)
