cspears2002 Posted August 17, 2009 Share Posted August 17, 2009 I'm trying to rotate some instanced pollen grains along x, y, and z from -45 to 45 degrees. I did create a rot attribute with the Attribute Create SOP. However, my expressions don't seem to be giving the results I want. I guess I should have paid more attention in math class. :-) microworld_v03_12.hipnc Quote Link to comment Share on other sites More sharing options...
edward Posted August 17, 2009 Share Posted August 17, 2009 The 'rot' attribute is a quaternion. It does not contain euler angles. Quote Link to comment Share on other sites More sharing options...
louis Posted August 17, 2009 Share Posted August 17, 2009 The 'rot' attribute is a quaternion. It does not contain euler angles. Does using the N and up vectors not give you a good result? You can rotate them very simply in vops with a transform vop.. Quote Link to comment Share on other sites More sharing options...
