Digital Asset

[samesami]

How do i create  a digital asset in way that when i click on one node it will create two nodes similar to the Volume deform node?

You can use the OnCreated script in the first HDA to create and link the second node.

Thank you for your reply. Unfortunately  i don't know much about python. So i check the volume deform hda to see if there's some sort of script which i can copy to use on my hda but i didn't see any script.

Can you please take a look at this sample file with an embedded hda:

Digital_Asset.hiplc

In the Scripts tab of your second HDA, at the bottom left there is an Event Handler field. Select On Created and it will produce a script module. Paste this code and save. When you create the colour_Two HDA, the colour_one HDA will be created and connected automatically.

(HDA naming should be kept consistent, e.g. colour_Two, colour_one <-- mind the capitalization!)

Python documentation for the methods I used can be found here.

hou.pwd() is shorthand.

kwargs is a dictionary, I'm accessing the "node" item.

# Get context
node = hou.pwd()

# Get the newly created node (self), use kwargs
self = kwargs['node']

# Create input node
c1_node = node.createNode("colour_one")

# Connect input node
self.setInput(0, c1_node)

# Layout
c1_node.moveToGoodPosition()

extra space where there shouldn't be one

Thanks Jikian, it works now.
