hi,

i have an asset geo as an HDA...
when modifying i typically create a new version and it will be saved with the new version number, which is fine, so i see a bunch of hda files in the hda folder...
but when an older version of the hda was placed in a hip, how can it be replaced with the new version? in maya i would "replace reference" in the reference editor.
what is the equivalent to this in houdini? and how can this be automated?

I thought it would be replaced automatically, but now I'm not sure anymore.
Anyway, to do it manually you RMB on the HDA instance > Action > Change Type

thx for the hint...i will try.

normally it shouldnt update automatically, because lets say you are middle in rendering with v1.1 and modify to a new v1.2...then when it automaticalky updates then you mess up rendering...

(but there are situations where you want to automate the update process)

oh, that's make sense right.

ps.
The above procedure I've described is a bit tedious, but it works for every selected node.
So in case you have multiple nodes to replace that are scattered in the network, you can ctrl+f to find and select them (by type)

You can create a button in the Toolbar that compiles which nodes are using outdated definitions:

e.g. a node named "namespace::myHDA::1"

import hou
customNodes = [x for x in hou.node("/").allSubChildren() if x.type().nameComponents()[1] == "namespace"]

for node in customNodes:
    definition = node.type().definition()
    
    if definition.nodeType().name() != hou.nodeType(definition.nodeTypeCategory(), definition.nodeTypeName()).namespaceOrder()[0]:
        print("Warning... Node instance is using older definition: ", node.path())

...then filter node.path()'s result to convert the nodes you want.
