control field in Gas Disturb

Recommended Posts

I'm trying to use vel in the control field.

Normally I would go inside the gas Disturb, find the control field, change it from float to vector and add a length node.

But when I tried in Houdini 19.0.622 I found a mismatch between the parameter at Gas Disturb level (named control field) and the parameter inside the vop (named control, and not control field)

Am I missing something? why is it named "control field" in the parameter interface of Gas Disturb, and named "control" in the vop?

control_field_lengthg.jpg is from Houdini 17 showing how it used to be done, and the other two images are from H19.0.622

It appears to be handled in the Data Bindings of the Gas Field VOP unless I'm misunderstanding it.

Ryew is correct. The idea behind the data bindings is you can associate an incoming field with a different name to a bind inside the vopnet. This especially handy when you have vopnets inside an hda
