Do you know if this could be done for cinema4d as well?

If not, do you know how can i open mod3 files with cinema4d?

Models imported using the MHW importer are off by -90 degrees on the X axis.

For example with this Great Jagras being off by -90 degrees makes it point up instead of forward.

Instead of:

This is not a problem for regular use but for batch operations with the LMT loader animations will be stuck in the -90 degree X orientation unless the operation includes a manual or python script rotation.

MHW game version: 167589

Issue:
When importing a .mod3 file with the "Import Skeleton" setting set to "Animation Armature" but the model does not have a skeleton an error will occur.
This is not a problem for regular usage but batch conversion of models with and without skeletons will run into the error.
Occurs on the accessory acc011_002, files used https://mega.nz/#!2DZU0aIA!4dQN_qmfO0g_ZgAKy80DwpG6IuBdtzycRQgzMegA9qA

Suggestion:
A check on import so that if "Animation Armature" is selected and the model does not have a skeleton then armature import is skipped.

I have attempted to replace an NPC's model with a monster's model, and I've hit a wall in regards of actually making it look somewhat correct.

In order to make the model fit a humane shape, I need to manipulate it's mesh and rig a bit.
I've attempted bending the mesh using hooks between the empty nodes and vertex groups, but pretty much any bone rotation results in extreme warping of the model.
That issue doesn't happen when the model is imported with an armature, as from what I understand, the joints have physical size that prevents the mesh from warping and folding out of existence.
Unfortunately this plugin doesn't appear to be able to export such an armature as a rig for the mod3 format, which at this point pretty much forces me to do some mesh + armature + empty rig shenanigans in order to both be able to modify the model properly and export it into .mod3.

(Would also be nice if this plugin was made compatible with blender 2.92)

Issue:
When importing any extracted .mod3 file the model has no material and the armature made of objects instead of bones.

This is not the case for the outdated TheCrazyT BlenderMhwModelImporter which gets the skeleton and a single material (joins multiple materials into one with broken UVs).

pl036_0000 Arm.zip

After installing the addon and checking it to enable it, it does not show up in the menu for import and export in Blender 2.80

When imported using the latest release m_arm050_0500 has merged weights on the right fingers resulting the movement of one finger pulling the mesh of another.


m_arm050_0500.zip
This is with the skeleton set to animation armature and weights set to standard.
I tested a few other arms and they worked fine so it may be just this model.

Update:
After more checking I have found that the legs of the savage deviljho armour, barioth arms and various chest armour has mixed weights aswell.

em013 (Fatalis) monster weight calculation is incorrect for weightDynamics 65 and 57 (8 weights) on Mod3VertexWeightExtended.

Changing Mod3VertexWeightExtended.WEIGHT_MULTIPLIER from 255 to 1023 and replacing the last weight (which is using an incorrect sum(1-...) with just 0 fixes it for this particular model (although it might break others, I haven't checked, but I don't know why the values have been different to begin with).

class Mod3VertexWeightExtended(CS.PyCStruct):
    WEIGHT_MULTIPLIER = 1023
    fields = OrderedDict([("tenBitWeight","uint32"),
                          ("byteWeights","ubyte[4]")])
    
    
    @staticmethod
    def weightFromBytes(byteWeights):
        return list(map(lambda x: x/Mod3VertexWeightExtended.WEIGHT_MULTIPLIER, byteWeights))
    @staticmethod
    def weightToBytes(weights):
        return [round(weight*Mod3VertexWeightExtended.WEIGHT_MULTIPLIER) for weight in weights]
    
    def marshall(self, data):
        super().marshall(data)
        self.weights = Mod3VertexWeightBase.weightFromBytes(Mod3VertexWeightBase.tenBitWeightSplit(self.tenBitWeight))
        self.weights += Mod3VertexWeightExtended.weightFromBytes(self.byteWeights)
        self.weights.append(0)
        self.bits = self.tenBitWeight>>30
        
    def construct(self, weightList):
        self.weights = weightList
        self.bits = 0
        
    def serialize(self):
        self.tenBitWeight = Mod3VertexWeightBase.tenBitWeightMerge(Mod3VertexWeightBase.weightToBytes(self.weights[:3]))+(self.bits<<30)
        self.byteWeights = Mod3VertexWeightExtended.weightToBytes(self.weights[3:7])
        return super().serialize()

Tried installing multiple times, it shows up on the list as installed and yet when I go to import or export it doesnt appear. I tried 2.7, 2.8, 2.8.3 and even 2.9 and all it does is tell me I need 2.8X. Tried again on 3.1 and STILL doesnt appear.

please please PLEASE update it for 3.1

an error with the scene header default settings being an int when it should be a list

Idea for 2.80 exporter, only export selected collections.

Attempting to install the add-on just results in a error saying Blender 2.8x is needed, despite currently being on Blender 2.82

Downloading the file using the 1.5v instead gives an error relating to a module

Blender 2.80 with the most recent plugin version.

Is this working?
