Hello, never seen a way to grab an attribute like that in a parameter channel (you probably should use a prim or point expression to lookup the value).

I had to try myself, so here's a little setup using chops to drive the sim time scale from the envelope (magnitude signal) of an audio file.

Thank you PaQ, I solved my problem now, by using the channel wrangle node.

The reason why I didn't use the code chop("/...") is because that I wanted it to give the value a condition



but I noticed that the timescale in pyrosolver couldn't be driven by a point attribute.
I looked at your hip today, and it inspired me that I can modify my audio signal instead of create an attribute in the sop,
so I did it with the channel wrangle node in chop network.



Thank you again for your solution!
it was really simple and helpful!

Tank you PaQ Wak!!
I'll try your method!

Hi there, I was trying to achieve an effect that the pyro sim speed is driven by the loudness of an audio file.
so I created an attribute in the attribute wrangle, and I tryed to control the pyrosolover timescale with it, but it didn't work, I wonder if there's a way to control dop parameter with a point attribute created in sop?






this was my silly move to try controlling the timescale with @simtime, I know it doesn't works that way now(lol).


After I typed @Simtime, It just stayed 0 all the time

ps:English is not my mother tongue, so please forgive me if I said anything wrong.
Thank you guys!
