pendraia,

He could not show everything in the short time of the seminar. Furthermore compared to Xurge and you I am just a beginner. But- I have found myself that it is better to start off with bump and displacement than the other way around, because if you add these things at the end (when everything is starting to look nice), you are too coward to do the bold things. Instead do it in the beginning, on a clean slate without being afraid of destroying it all.
