One thing I do wish to note in regards to this tutorial is that using dynamic subdivision on all models will result in an error message and Carrara crashing. I BELIEVE this is a memory issue. Though I can't be sure.
If you come across this. The solution is to use the subdivision within the shader. And use it in conjunction with the dynamic subdivision. Watch the settings though as you can lose the definition of the model with the wrong settings.
Increase the min sample count if you have a model with lots of detail (ie. pores, etc.). Usually you can get by with a subdivision level of 3-4 in the shader and be fine. You can tweak the amplitude to bring out the definition. And increase the smoothing angle to reduce the roughness of the displacement if necessary, just make sure not to lose your details. A setting of 2-3 with dynamic subdivision should be enough.
