Hello,
this is related to Stephen Knipping's Advanced Dynamics Tutorial Series. I'm not sure if his tutorials qualify as being part of the SideFX.com - if not, apologies but I'm hoping we can move it to the Technical Discussion instead.
So I'm a bit confused about the SmokeObject's Initial Data and the VolumeSource. In Applied Dynamics II he says that he doesn't need to input Density SOP Path and Temperature SOP Path in Initial Data because he will use the (Houdini 16) Source Volume to source those. So now in Houdini 17 - following his Houdini 17 update - I use a VolumeSource. Everything is great so far.
However when I was trying to cache my sim using a File SOP and a DOPImportField, it wouldn't play the cache unless I added my SOURCE (PyroSource's Null) to the Density/Temperature SOP Path. Once I did that it would play the cache I had saved.
So I'm a bit confused, I may be doing something wrong, or this might just be the case.
Thank you and again I'm sorry if I should have posted this question in the Technical Discussion.
PS: Sorry but English isn't my first language.
