Mjag07 Posted August 27, 2018 Share Posted August 27, 2018 So I am curious about one of the tools presented by Ben Watts. So my question is in regards to Controlling FX starts around 3:11. I know its a custom tool and looks like it would be super handy. Any ideas on how to replicate this tool for myself would be awesome ? Awesome Siggraph presentations by the way. I really enjoyed them. Cheers Mike 1 Quote Link to comment Share on other sites More sharing options...
Atom Posted August 27, 2018 Share Posted August 27, 2018 To me that looks a lot like the existing Ocean tools. Check out the master class on Oceans. 1 Quote Link to comment Share on other sites More sharing options...
tamagochy Posted August 28, 2018 Share Posted August 28, 2018 He told you can send him the message with questions, so sent it to him, maybe he will send you simple version or explain how to do it ) Quote Link to comment Share on other sites More sharing options...
Jesper Rahlff Posted August 28, 2018 Share Posted August 28, 2018 Pretty sure Ben did not create it like this, but my recommendation would be looking into MOPS. Alot of the functionality Ben is showing is integrated into MOPS. Quote Link to comment Share on other sites More sharing options...
hoi Posted August 28, 2018 Share Posted August 28, 2018 Fully agree that having a tool to create transitions is pretty handy. I made super simple one based on the shortest path, But can't live without it anymore. (probably should make this into a proper asset someday) Can use speed attribute to control the transitions speed, and can output an up vector if you want to use it for copies. It's not based on uv's / axis like Bens though. But hopefully it's helpful to get you started.

theBlues Posted August 29, 2018 Share Posted August 29, 2018 Hi, I'm also very interested in the tools he used, and I think I got some progress. About the UV step - I think it's only necessary when you have a geometry - some poly geo, I don't think he uses the UV in the curves example simply because - the curveU attribute already gives values from 0-1, although I must say it's possible I'm wrong Another interesting thing is - when you resample a curve - the curveU attrib outputs from 0-1 only in "straigh edge" mode - using "subdivision curve" (as in the presentation video) outputs some strange numbers way below zero (e.g. 5.23545454*e^5) You can see in this VOP scheme - my take on it - it simply creates a 0-1 float value from the frame range you input and adds it to the curveU - hence offsetting the value to the point from white to black (0-1) and binds it to the morph attribute, I don't have the hip file atm but, it's pretty straight forward to recreate it. Also I'm offsetting this value to each prim with random and fitrange nodes. Let me say I'm pretty new to Houdini, so if anything I'm just as interested as you what the experienced users think on the subject. Quote Link to comment Share on other sites More sharing options...
zinogino Posted October 21, 2018 Share Posted October 21, 2018 Tried replicating his HDA but tough luck in getting some of the parts to work. Anyone had any success? Quote Link to comment Share on other sites More sharing options...
Mjag07 Posted October 21, 2018 Author Share Posted October 21, 2018 (edited) I haven't had much luck either. I contacted Ben a while ago he said he would help but super busy atm Edited October 21, 2018 by Mjag07 Quote Link to comment Share on other sites More sharing options...

bwatts Posted October 30, 2018 Share Posted October 30, 2018 Hi Guys, Sorry I haven't had time to help you with this. I'm presenting at Node fest this November. I'll be covering some of these techniques in detail. The videos will be online as usual. Cheers, Ben. Quote Link to comment Share on other sites More sharing options...
Matsidefx Posted November 1, 2018 Share Posted November 1, 2018 (edited) I m not sure it is the right technique but you can watch this . Ben use uv tool to control the ramp may be with primuv. Edited November 1, 2018 by Matsidefx Quote Link to comment Share on other sites More sharing options...
Sandov Posted June 1, 2023 Share Posted June 1, 2023 Ben is such a beast, but he didn't mention about the radial part, I wonder how he made it?... Quote Link to comment Share on other sites More sharing options...
