Hi all.
I have found that sometimes a node into a HDA returns a warning, but this
warning is not showed in the HDA node, one level up.
So HDA is doing nothing but for the user is not obvious something wrong is
happening in the tool, unless you dive into it and catch the node/s with
One good example is Object Merge which returns a warning if it can't load
geometry and this warning is not shown in the HDA node.
So is ther anyway, better if it using python, to explicitly set a node as
error during cook and set the error message.
I have seen there are mthods in hou.Node to get node's messages abd warning
but not to set them, or to set the cook state of the node.

Un saludo
Best Regards
