PhiiLL Posted August 17, 2017 Share Posted August 17, 2017 Hey guys, I'm new into vop's and wonder why I dont get any result, when distort the nomals through an turbulent noise node? Is there any tutorial which covers the vop basics? Like what the colors mean and what datas need to flow through nodes to get results? Thank you for your help Quote Link to comment Share on other sites More sharing options...
Atom Posted August 17, 2017 Share Posted August 17, 2017 (edited) The pos input must be driven by P. Try connecting N to amp and you might get a varying result on your normal, but why would you want that? There are a lot of tutorials available. Have you tried exploring the Learn menu on the SideFX.com website? Edited August 17, 2017 by Atom Quote Link to comment Share on other sites More sharing options...
3dome Posted August 17, 2017 Share Posted August 17, 2017 maybe have a look at the help there might be some explanation in them. the houdini help/documentation is really good but I dont just want to send you to the docs, so: green (like P and N) is vector3 data light blue-ish is float data blue is integer that light orangy color is file/string data then there are a couple others like yellow for BSDF light purple for matrix3 dark purple for matrix4 green-yellow-ish for vector4 "neon"green for vector2 and there might be others that I forgot as to why you dont get a result from the vop - did you set the display flag to the vop? coz when I plug in the same things the normals change like expected Quote Link to comment Share on other sites More sharing options...
PhiiLL Posted August 17, 2017 Author Share Posted August 17, 2017 Thank you for your answers 5 hours ago, Atom said: The pos input must be driven by P. My problem is, that I knew that already, because it was written in the docs, but there isn't written, why I have to plug P in pos. I'd like to know why I have to do it in this way. I'd like to have a more deeper unterstanding of the network. But I don't know where to get those information :/ Quote Link to comment Share on other sites More sharing options...
Guest tar Posted August 17, 2017 Share Posted August 17, 2017 it's nothing special or unique but normal maths and programming. I'm sure the others are just smoking too much and not testing as it works. See attached. NormalsRandom.hipnc Quote Link to comment Share on other sites More sharing options...
