billowy smoke sticking to translating objects

[smurphy666]

How can I attach a billowy_smoke material to an iso-offset sop that is translating so that the texture sticks?

I need to use some kind of rest position I guess...

thanks

Hmm.... I'm not really sure about billowy smoke, but if you only need to translate the isoOffset, if you can do it at world space, that should solve your problem. If not, may I recommend reading this thread:

thanks for the link ... i didn't quite understand the ...

"Edit: I think I got it now. Had to reread Jason's post a couple of times.

make 3 extra volumes. In the first one, add an attribcreate sop, set to string, called "name", with the value "rest.x"

In the second one, the value is "rest.y"

etc etc.

In the shader, there is a vector parameter called "rest"."

I altered the file testnoise3_166.hip mario created and added three atribcreate sops with class primitive .. type string and string set to rest.x etc

But I am not entirely sure if this is what I should be doing... I have uploaded the file . Do you have an example file I could take a look at?

cheers
