Hi all,
I wanted to set up an hda with a attrib paint inside and have the default state be the brush paint tool. I imported the block into the hda and set "sidefx_attribpaint" as the "default state" in the HDA but I get a python error back:

Houdini 19.0.657 Python 3 on linux.
Bug or me?
Thanks

Hi, I tried this but it seem very problematic in several ways. Trying to use attribpaint in a subnet or HDA and doing some UI things seems like a minefield. I don't know what to think of this.

Edit: If I had to do this myself it might work if one allow the artist to dive into the subnet/HDA. A button on the subnet/HDA that selects the attribute paint node inside is a work around.

Edit2: While doing the work around I got this (H19.5):

Traceback (most recent call last):

    return func(*args,**kwargs)

    return _hou.SceneViewer_beginStateUndo(self, label)
hou.OperationFailed: The attempted operation failed.
beginStateUndo error: Undo is suspended.

Comment: It is a bit wierd, because the work around did function for a while. Then when I'm trying to record it, this message appears.

Interesting. Well for now I've just left it outside the HDA.
thanks!

I get similar python error when trying to have attribute paint inside a HDA with the Jeff Lait method. Seems like it does not with houdini 18.5 and onwards. Can someone from sideFX please look into this and let us know? @mabelzile
