jumper Posted February 11, 2011 Share Posted February 11, 2011 Hey, I am having problems with noise pulsing on the pyro shader ... I am using the dual rest position - set to 20 on the pyrosolver and fireball_pyro shader. The noise is really pulsing quite badly ... am I missing something? I am using H11.0.653 Thanks!

Stephen Try to raise the rest rate. The 2 rest fields are "crossfading", so if your interval is to short it might get noticeble.

jumper Posted February 14, 2011 Author Share Posted February 14, 2011 Hey, Thanks for the help... extending the rest reset position did indeed help a lot! (it did soften the features a lot too - which I guess is due to the long mix between rest positions). I am just surprised this crossfading happens globally... would be great if there was a way the rest pos somehow tested how far it was streched locally and then reseeded the rest position 2 when and where needed. I guess this is easy for me to say but I have no idea of the practicalities of implementing it! cheers! Stephen Quote Link to comment Share on other sites More sharing options...
Macha Posted February 15, 2011 Share Posted February 15, 2011 (edited) Could this be related to Journal Entry: Monday, Febuary 7, 2011 Houdini 11.0.650: The Pyro Shader will now properly respect a 50 frame rest reset. Previously, the VEX code had a default of 20, not matching the UI default. This caused the shader to actually use a reset rate of 20 when the UI was set to 50. This pyro shader behaviour has been discussed before and I have experienced it myself. Edited February 15, 2011 by Macha Quote Link to comment Share on other sites More sharing options...
