Merge All option?

[steven]

I'm restoring a bunch of old subnets that have 400 dangling transform sops and none of them are merged. I'd like to connect all the xform sops into one merge sop that I can display from. Is there a merge all technique for this? I've exhausted my useless bag of tricks--never needed to do a merge all until now. Any tips before I look at hou.Node and travel down that path?

There's a couple ways you could do it I suppose.

One way would be to have a general tool that merged all your selected nodes together automatically for you, the other a more one off scripting approach.

For the scripting approach you could do something like this:

def mergeXforms(container):
    xform_nodes = [child for child in container.children() if child.type() == hou.nodeType(hou.sopNodeTypeCategory(), "xform")]

    merge = container.createNode("merge")

    for xform in xform_nodes:
        if len(xform.outputs()) is 0:
            merge.setNextInput(xform)

    merge.setRenderFlag(True)
    merge.setDisplayFlag(True)
    merge.moveToGoodPosition()

I've also attached a tool I wrote a while ago that handles easy merging of selected nodes in all contexts except OBJ and VOPs. Just select some nodes and run the tool. It should merge them together.

you can just select all the xform sops, either manually or by network editor's "Find Node..." button to search/select the xform nodes. Once selected, wire the output of 1 of the selected nodes into a merge sop. That will wire all the selected nodes into your merge.

Thanks Spencer!

Graham, I'm going to be using this script with some small mods next week, I think. Just saw another 50 subnets that this will be of great help.

Huge, huge thanks guys!
