the full sanostol answer in case i misundersood something to solve the mismatch in the results, add a degree to radians vop in You network in front of all trigonometric functions, like sin and cos, they expect all values in radians. in hscript degrees are ok
for the parameter stuff, I'm not sure what You are trying to achive. It looks like You are writing data to geometry in the first set data , and then read it out later. I'm not sure why You want this, but that does not work that way in houdini,You can not work import data in the same vex tree that is set here. that must happen in a previous vopsop 2014-05-06 16:50 GMT+04:00 Nika Ragua <nikaragu...@gmail.com>: > > How to port our precious ICE stuff into houdini vex.
