angadrana Posted June 9, 2018 Share Posted June 9, 2018 Hey guys, I'm trying to create a slow motion explosion but can't get it right using the Timescale, timesteps or increasing the FPS. All of these completely change the look and shape of my explosion. How do I make an explosion 10 times slow motion than it's actual speed without changing its look or shape completely?

rbowden Posted June 9, 2018 Share Posted June 9, 2018 Either use the upres solver to do it (will require an additional sim) or maybe use the volume retime in the qlib tools. I haven't used the qlib one myself but, I thought I remember seeing a volume retime sop in it. Quote Link to comment Share on other sites More sharing options...
Atom Posted June 9, 2018 Share Posted June 9, 2018 Check out the volume_retime_ql_SOP.hip file at this link. https://github.com/qLab/qLib/tree/dev/examples One thing you will have to have in your sim is a vel field for this technique to work. When you are caching your sim to disk make sure to include it. Quote Link to comment Share on other sites More sharing options...

6ril Posted January 20, 2020 Share Posted January 20, 2020 (edited) Hey guys, I'm interested in trying out that qLib volume retime, I'm a bit lost on how to use it out of the exemple .hip file. I tried copying the node into another hip, but I get this : Warning This node is using an incomplete asset definition. It will not function properly until the asset library containing the full definition is installed. -EDIT- I found out : you will need to install qLib tools: https://github.com/qLab/qLib Edited January 20, 2020 by 6ril found out Quote Link to comment Share on other sites More sharing options...
6ril Posted January 20, 2020 Share Posted January 20, 2020 NAh ... can't get it to work I'm under windows I've downloaded and unpack the qlib in my houdini17.5 folder and I've created a folder packages at the same place, with the .json file into it. I've tried the same in houdini17.5/config I also tried to modify my .env file with what I could understand from the provided .env file nothing works. Can someone assist me ? Thanks, Quote Link to comment Share on other sites More sharing options...
Sepu Posted January 20, 2020 Share Posted January 20, 2020 if you are in 17.5 why don't you use the retime node that comes with Houdini? Quote Link to comment Share on other sites More sharing options...

Benyee Posted June 26, 2020 Share Posted June 26, 2020 i do not know if this can help you, extract package to a folder,say D:\Home\houdini18.0\config\qLib-0.2.5,and modify env file. Quote Link to comment Share on other sites More sharing options...
