Lyonz Posted September 18, 2010 Share Posted September 18, 2010 Hello wondering if anyone knows how to create a simple transition, as im wanting to reveal a piece of metal as a null object goes around the path of the metal. Thanks Quote Link to comment Share on other sites More sharing options...
graham Posted September 18, 2010 Share Posted September 18, 2010 My first thought would be, depending on how your metal is constructed, to use a Carve driven by your Null objects position along the shape curve. In the attached file I have my crappy metal object type thing created by sweeping a grid along a curve. I also have a null moving along the backbone path that it's being swept along. After the node that the null is looking at for the path I throw down a Carve SOP and have its Second U parameter channel referencing the position along the path of the null. As the object moves along, more of the curve is revealed and more of the object is created. This method is of course very specific to how your piece of metal is created. reveal_curve.hip Quote Link to comment Share on other sites More sharing options...

Thank you for replying i see the method used and have tried something similar in past projects using a sphere. The problem im facing is my logo is more complex as it is beveled and also connected in places. Example the letter B. At the moment im using a boolean to reveal what i need but am coming up with sharp spike problems. Is there a way to smoothly reveal geometry ? As i would do this in a compositor but im wanting my logo to spin at the same time. Edited September 19, 2010 by Lyonz Quote Link to comment Share on other sites More sharing options...
