akirasun Posted August 4, 2022 Share Posted August 4, 2022 Hey guys I'm trying to reproduce same noise pattern which originally created by blender. In original video(@00:01:40), author used Mapping node to manipulate UVs. In houdini, I tried UV Position VOP node but unfortunately can't get reasonable result. Thanks for any help Cheers NoisePatternTest.hiplc Quote Link to comment Share on other sites More sharing options...
