[MPlug] Set array doesn't work

[Rémi Deletrain]

Hi everyone,

I try to set a blendshape weight plug. I used this solution :

mfn_weights = OpenMaya.MFnFloatArrayData()

mo_weights = mfn_weights.create()

mfn_weights.set(OpenMaya.MFloatArray(i_target_count, 0.0))

mp_weights.setMObject(mo_weights)

but it doesn't work. I have a same problem for set a vertex weights of target.

This solution works with array of point (for target offset) but not with array of float or double...

Anyone have solution ?
