copy a mesh with transforms baked in

[justin hidair]

    writing a node here *see joint file*

def compute(self,plug,datablock):
        pass
        if(plug != myclass.outputmesh):
            pass
            return om.kUnknownParameter
        pass
        inputmesh=datablock.inputValue(myclass.inmesh)
        outmeshdata=datablock.outputValue(myclass.outputmesh)
        outmeshdata.copy(inputmesh)

datablock.setClean(plug)

This will copy the mesh BUT will put it at origin right after!
it doesn't even care about the transforms !!! (on the image , rotations...)

What I want : I don't want to link the transforms, I want them to be baked in the output(copied mesh) (so technically it's like the transforms have been frozen on the copied mesh)

I had the same issues years ago, and if i remember correctly, the reason of that it's because you using outputMesh, and not worldMesh,

It didn't change anything apparently, I'm suppose to play with matrices right ? ?

[Rémi Deletrain]

If I am not mistaken the copy of the MFnMesh only copies in ObjectSpace.

It is therefore necessary either to move the transform or to multiply all the points by the WorldMatrix of your transform

Hi all I fixed it, thanks to you , the solution : instead of using outmesh, I use worldMesh , then I use MFnMesh.copy() with the inputmesh : MFnMesh(inputmesh.asMeshTransformed(), om.MFnMeshData().create()) ..
