Problem with boneMatrix

[Arfanu]

I triying to build readed skeleton to noesis but for some reason isnt working why? Can anyone check code and fix?

fmt_fmlb (4) (1).py

First: wrong sub forum! That's not a graphic's format problem.

2nd: So this is Durik's script which you seem to have patched wrongly? (Since Durik's script usually work like a charm...)

---------------------------------

To get rid of this annoying "RuntimeError: Invalid type provided for bone matrix"

I made these changes (without knowing what I did exactly):

            elif ntype == 10:
                bs.seek(80, NOESEEK_REL);
                trfm = NoeMat44.fromBytes(bs.readBytes(0x40)).toMat43()
                #trfm = NoeMat44.fromBytes(bs.readBytes(64))
                bs.seek(80, NOESEEK_REL)
                print("trfm:", trfm)
                #bone = NoeBone(pidx, trfm, bonename)
                bone = NoeBone(len(bones), bonename, trfm, "dummy", -1)
                bones.append(bone)

(Be sure to replace the string "dummy" by a parent bonename variable, btw.)

Result:

Ok thanks the parent variable is pidx but dont worry i rename but thanks

I moved this topic.

I don't understand why you clone topics (and from different accounts).

*( I already wrote to you that it is worth indicating the original author, even if you edit the original plugin)

having the complete structure that I researched and provided to you, you still did it your way and incorrectly

I made some minor edits (in reading nodes and creating bones), creating one model with a skeleton and meshes (and not all as separate models).

as I wrote earlier. the game has a text analogue of fmlb, in fml format. looking inside it you can understand the structure in more detail. for example, the parameter "dep" (which you removed in the plugin) is responsible for the depth of the node, on its basis you can specify the parents of the bones by building the correct hierarchy

*(I think that's enough info for now. So this is the last message regarding fmlb.)

Ok ok but you finally implemented support for skeletons and thats if suficient for the moment very thanks and i prommes this is the last post about fmlb files starting now every new request related to fmlb files i going to post here forever

I can load skeletons but i have problems loading bone weights

1. you are constructing the skeleton hierarchy incorrectly

2.you constantly ignore the structure that I provided you (see message above). if you look into it, you will see that there are 4 bytes for indexes "wi-vec4(ubyte)"

3. the error says in plain text: "unwanted object". look in  "inc_noeis.py" >> "class NoeVertWeight:"

 

fast fix u code: (without checking for functionality)

Spoiler

        bs.seek(idoffs)
        boneIndices = [[
            #NoeVec3((
                bs.readUByte(),
                bs.readUByte(),
                bs.readUByte() + bs.readUByte() * 0 # read and skip 4 indx
            #)) for _ in range(vCount)
            ] for _ in range(vCount)
        ]
        print(boneIndices)
        bs.seek(woffs)
        boneWeights = [[
            #NoeVec3((
                bs.readHalfFloat(),
                bs.readHalfFloat(),
                bs.readHalfFloat()
            #)) for _ in range(vCount)
            ] for _ in range(vCount)
        ]
        
        #combine indices and weights
        NoeVertWeightList = []
        for x in range(vCount):
            NoeVertWeightList.append(NoeVertWeight(boneIndices[x], boneWeights[x]))

 

*(and you need to build a bone map for bone indices)

@Durik256: without you, we would be lost. Thanks for your support and patience!

btw, I saw two lines

            elif ntype == 3:

in your fmlb code. Shouldn't the 2nd one compare to '4'?

yes you are right, it is a mistake) but these are quick edits of the topic author's code, that is, not the final version, he should have written his code based on this, and noticed what you noticed
