For completion, here is what I found out. If I loop through the cvs and set
the weights, it works as expected.
crv_1 = pm.curve(d=1, p=[(0,5,0), (10,10,0)], n='crv_1')
crv_2 = pm.curve(d=1, p=[(0,0,0), (10,0,0)], n='crv_2')
bs = pm.blendShape(crv_1, crv_2)[0]
print(bs.inputTarget[0].baseWeights.get())
# result: ()
num_cvs = crv_2.getShape().numCVs()
# set the weights
for index in range(num_cvs):
bs.inputTarget[0].baseWeights[index].set(1)
print(bs.inputTarget[0].baseWeights.get())
# result: (1.0, 1.0)
BR,
Johan
