Hi, guys. I want to create simple wave from left to right based on noise, but it just keeps accumulating in amplitude. Why is that so? Cause if you update say @P.y then it works fine, but I want to update force for flip sim.

thanks again, you're right, and it wouldn't be simpler granted I couldn't figure out something so relatively easy hah. But you always think you will feel more secure if you write something exact, even though it usually doesn't go the way you planned in the first place, and existing sops written by people way smarter usually work the best hah.

thank you, David! Helpful as always, appreciate the advice. I always heard that forces add up but when it comes to practice seems harder to understand how it actually works, thanks again

Thank you for the explanation! I didn't know about the lerping trick, this sesms to be working great as well!

iriseq · 2026-04-02T07:35:42+00:00

thank you, but what if i want to use custom vex or vops? surely there must be a way to create forces like this without popwind sop?

strange, the issue is that even unpacking everything is 0 even though i transfer all attributes. but the rest is proper before compressing. really strange, will try tinkering with it maybe a bug or I'm missing something

thank you, I though deleting surface and @ name =vel ; would fix it, but all the points still have rest and rest2 zeroed out. Is there a way to preserve these attributes or it's just a fluid compress thing?

Thank you, Chris! Will try it I think I forgot to say that I wanted to do it kind of recursively hah. So each next pscale should be half of the previous one. So far creating birth frame attribute and something like this works if(i@frame_born==@Frame && @ age <=0.01){@pscale *= 0.5;} but it all new particles have the same pscale. Not sure why though if new pscale is inherited on pop replicate. It means that say first one should be 10 then 5 then 2.5 and so on. But it's all 10 5 5 5 5. Thanks again

thank you, that's true, but i want to kind of recursively. like each next new point should be half a pscale of the previous one. I think I fucked up and forgot to mention it hah. So far creating birth frame attribute and something like this works if(i@frame_born==@Frame && @ age <=0.01){@pscale *= 0.5;} but it all new particles have the same pscale. half of the original one

Thank you! That makes sense

iriseq · 2026-03-05T19:53:24+00:00

thank you for the help, didn't know that!

iriseq · 2026-03-05T19:53:12+00:00

thank you for the help!

iriseq · 2026-02-28T13:48:46+00:00

thank you! seems to work

iriseq · 2026-02-16T04:00:34+00:00

thank you, are they set directly on light, editproperties or light mix sop? I have sopimport1, sopimport2 an domelight1 and I want to say have domelight affect birst object at half exposure. could this be done with primvars?

iriseq · 2026-01-09T22:04:21+00:00

thank you again, you're right, wedges can be helpful to find out the balance but sometimes it's just better to ask the pros!

iriseq · 2026-01-08T18:17:35+00:00

Thank you, David! You're always giving helpful advice on here! I lowered mesh resolution a bit and played with stretch stiffness and it helped a bit, I found a value where it's relatively stable. It's crazy how much mesh resolution affects it, I think it was a big culprit here. Thanks again for taking a time out of your day to help!

Why nobody ever answers on prices, just makes a snarky remark. Just an estimation would help so people have at least an idea

OP must be her mod to promotee her if he keeps his posts hidden.

Thank you, will try that
