[Closed] SDK: modyfing vertex normals

Just one more question (not entirely related to the topic), now I’m trying to control the strength of randomness of these normals, so I created the spinner control and do some simple multiplying:

resultVector = (currentVector + randomVector * spinnerVariable).Normalize();

Works fine when I change this value manually, but does not work when I animate this. Could you give me any hint?

is the spinner set to Animatable in the param block definition ?

Yep. It’s something related to “LocalValidity”, I’m I correct?
