Hi table-state,
Thank you for the kind feedback.
Please test the file from above, which I have problems downloading myself (That is the first one with the current forum). Sorry about this. I will try this

Please test this, as I had mixed results with your file.
The problem with Cautics is that the material has no option to stop it, so any Blend via Vertex didn't wasn't working. It is tricky.
Cheers
