WebMay 26, 2015 · The further away the object is from the ground the harder it gets! The problem happens on the next frame after you align your plain to the normal, because then your raycast is going to hit a different normal an will thus get a different rotation. You absolutely must find a suitable (L)erping method and smoothly rotate towards the normal. WebBecause the rotation is driven by rand(@ptnum), each point gets its own random rotation, meaning each circle gets its own random rotation. When this nest of circles is then passed to the 2nd copy sop, it just does what its told; finds each point, and copies a box onto it, using @N and @up to orient it.
