Hi, Thank you Lauriepriest for giving your valuable time and for the prompt reply. I understand what are you trying to say. But i have got stuck at one point in this book' Mastering maya 8.5'. If you have this book can you try the lesson in page 68 under Nodes and Hypergraph. When i try this lesson on my computer i get the hypergraph view as shown in figure 2.17 but when i select the object 'HammerHead' and then click on inputoutput connections i dont see the node 'HammerLayer' as shown in figure 2.18. I have spent almost 4 complete days to find out where i am missing. If i open the readymade scenes 'step3.mb' provided in the cd that comes with the book then i see the inputoutput connections as shown in the book. Please try if u have this book. I dont know anybody who can help me other than this forum. Thanks and regards, Mahesh
