Im sorry for that, and at the same time, thank you for sharing tutorials with us all this time. Also, thank you for your tutorials in 3d World magazine.Anonymoushttps://www.blogger.com/profile/02745335350707917945noreply@blogger.comtag:blogger.com,1999:blog-6897650046637838131.post-64183266818373809862012-07-25T13:34:55.660+02:002012-07-25T13:34:55.660+02:00Your content is shows potential, m gona add this t...Your content is shows potential, m gona add this to my bookmarks.<br /><br /><a href="http://www.allvectors.com/black-wall/" rel="nofollow">vector free</a>salenayoungshttps://www.blogger.com/profile/15713603950173567454noreply@blogger.comtag:blogger.com,1999:blog-6897650046637838131.post-71669450824474338142012-04-10T21:46:37.690+02:002012-04-10T21:46:37.690+02:00Before ICE made our lives (mostly) easier, a reall...Before ICE made our lives (mostly) easier, a really good, stable/proven "cheat" alternative to your approach was to use the classic Shrink Wrap deformer to "project" a poly square from which to derive transforms.<br /><br /><br />The "long" version:<br />1. Make a 1x1 grid object roughly of the desired sample size, then place it relatively close to the target surface. (If you scaled the grid, do Transform-Freeze Scaling before proceeding.)<br />2. Swith to Animation Construction Mode for this step and with the grid selected, do Deform->Shrink Wrap then pick your surface. Set the wrap mode to "Closest Smoothed Surface".<br />3. Make a cluster of all (4) points of our square.<br />4. Make a null and do Constrain->Object-To-Cluster, then click on the cluster from the previous step. (Be sure to check "Active" in both the Tangency and Normal tabs of the constraint.)<br />5. That's all. Now whenever you translate the grid object, your null will reliably slide along the surface.<br /><br />This trick is easy, super stable, requires no ICE/scripting/expressions/math knowledge and works with NURBS, polymeshes and even curves.<br /><br />It's how I rigged the projected eyeballs of the Excel Donut character featured in my 2010 rigging reel at http://darkvertex.com<br /><br />Love this blog of yours, by the way. Been a silent lurker for a long time. ;)Alanhttps://www.blogger.com/profile/07824864580502761476noreply@blogger.com
