    To whoever have doubts about the cache like me, if you are using 'explicit path' instead of 'constructed' in the file cache node, you need to replace $F with $FF or $T in order to write the substeps correctly. I would use $FF in 'constructed' path just in case too. You can see more info by hovering the cursor in the 'substeps' option in the file cache node.

      He didn't cover all aspects, he skipped over how to cache the sim and went straight to importing the cache files. I'm confused now how to create the cache.

    Thank you for this amazing tutorial. I'm new to Houdini and this really helps! But I have a question: I followed your tutorial exactly but caching the fluid sim took AGES. And my system isnt that bad at all. At one point I just cancelled it and went to bed. Today I saw that every file saved in the cache folder was just 2kb and this obviously cant be right. I just used the same houdini file and lowered the substeps in the I/O to 4 to try it out again and it worked. This was also noticable since every cache file had different sizes just like in your video. But I encountered a problem later. I now did this whole thing again and I again have only 2kb for every file but I cant fix it again and forgot what I did to fix it earlier. Can anyone help me? I am on 20.5
    EDIT: HA! I remembered. Maybe this is just a complete beginner mistake but maybe there is also a complete beginner making the same mistake. Before caching in the "dopimportfield" node that you see at 11:13 it says "presets" on the bottom. Click it and choose "flip fluids". If I think about it, it makes sense because you have to tell it what to cache. But I just couldnt figure it out earlier.

    Hi can you explain how your node Null CONTROL get you a frame section at 14:07 ? I don’t have it…. If anyone can help me

    • @FabianStrube
      @FabianStrube  ปีที่แล้ว

      Hi, you can create a Null objects in the obj context and use the edit parameters interface to add a float slider. Simply right-klick it and copy parameter and go to you retime sop and paste relative references into the frame retime slider. Now you can control the retime from outside your sop network

    Hi! I got this to sim with the .0005 , but redshift would crash when I tried to render, so I re-simmed at .001 and made sure to change it to v2 on the file cache after the DOP I/O, but now the position of the bottle is slightly off and I didn't change any settings. I did change the re-time by 1 frame but since the control null is affecting both retimes, that shouldn't matter. Super weird!

    i did not understood the retime part. I wanted to do your idea whitout watching the video step on step, so I created the fluid sim in a geo node with a dopnet by myself, all this part is working, but i never did a retime before and its not really working. Did u just animate the retime parameter in your null? because i tried it but it dosent affect anything at all

    • @aaronv2photography
      @aaronv2photography ปีที่แล้ว

      YES! The cache step was super important since you can cache from the dopnet. Or the output in the solver. Or make a filecache node which I don't know where to do any of the cache since NONE of the attempts I have made will cache the substeps like is shown in the video.
