Awesome! I'm a maya veteran transitioning to houdini, and your tips are spot on! Deforming textures, upresing, quaternions, everything I was looking for. Thank you!
Sure, I'll keep that one in mind! If you're a subscriber to CG Forge, I also have a lecture that goes into rest fields in my pyro courses that may help you out with that situation.
Great tutorial, but what is that rest ratio for? I am coming from a mantra background and there I just used Rest and rest2 I don't think there I used anything as ratio
From my understanding, the ratio is used to blend between the rest 1 and rest 2 fields. If we only used one rest field, the noise would get "smudged" over time and look strange. So, to solve this problem, the idea is to use two rest fields and blend back and fourth over time to prevent this smudged look. As one of the rest fields becomes fully present, the other resets its position in space, and that's how you prevent the smudged look. I've never really changed the default ratio values to be honest, so I wouldn't recommend changing them unless you had a specific reason to. Steven Knipping goes over this in his pyro course really well, so if you'd like to see this happen visually, I'd recommend checking it out.
Hey Tyler, do you know if there's anything different on Houdini 18.5? I can't make it work here I did it once, based on your tutorial, and it worked straight away. Not sure which version was it but it wasnt on 18.5 for sure You have awesome tutorials btw, thx ;) - Alvaro
Hey Alvaro, I was able to get things working properly on my end over here. One thing I didn't mention in the video which may help is that on the Unified Noise, try a bias of .3 a gain of .7 clamp the output range from 0 to 1 and set the final amplitude to 2. I think that unified noise has a hard time cutting through sometimes and it might freak out of the noise values go negative.
@@cgforge Hey Tyler, The issue here wasnt OpenCL as well, but both rest_ratio detail attribute. It looks like the dual rest solver isnt reading it if its an attribute. To fix it I converted these attributes to volumes and now it's working. I'm on Houdini 18.5.532 btw I'll leave the link with the fixed scene here in case anyone else have the same issue www.dropbox.com/s/aext6fsbv54310i/Pyro_REST_RnD_0101.hiplc?dl=0
