Hi Jonasz,

I had more success with the following snippet in Python:

# Retrieve object of interest
my_object = TheSystem.NCE.GetObjectAt(1)

# Retrieve scatter data from the relevant face
scatter_data = o11.CoatScatterData.GetFaceData(0)

# Retrieve scatter settings
scatter_settings = scatter_data.CurrentScatterModelSettings._S_Gaussian

# Retrieve sigma parameter
sigma = scatter_settings.Sigma

# Print current sigma
print(sigma)

# Change sigma to a new value
sigma = 1.2345

# Apply new scatter settings
scatter_data.ChangeScatterModelSettings(scatter_settings)

I hope this helps. The main difference is that I used the _S_Gaussian property to sort of cast the settings to the Gaussian scatter model.

Also you need to use the ChangeScatterModelSettings method to actually apply the settings.

Take care,

David

Thanks David,

Your solution worked perfectly. Thanks for the insight that I had to use the method ChangeScatterModelSettings:

o11 = TheSystem.NCE.GetObjectAt(11)
o11_face1 = o11.CoatScatterData.GetFaceData(1)
o11_face1_model = o11_face1.CurrentScatterModelSettings._S_Gaussian
o11_face1_model.Sigma = 2.2
o11_face1.ChangeScatterModelSettings(o11_face1_model)

Best regards
