From inside the material library, is it possible to Save a custom Karma material builder or material subnet as a HDA. I created a HDA using karma material builder as a base and inside is just a mtlx setup, then saved it out as a HDA. But it doesn't show up on list anywhere. Is this possible to do, it worked okay in sop and stage context?

Well not the best solution but slightly better/more concise than dragging to shelf

import hou

cwd = hou.selectedItems()[0].parent()
node = cwd.createNode('User::base_texture_mtl::1.0', 'base_texture_mtl')
node.setGenericFlag(hou.nodeFlag.Material, True)

As shelf tool - downsides need to have node(s) selected, but okay if something messes up or need to version up

In the ‘material libray’ node, there is a parameter called ‘Tab Menu Mask’. It seems to define what kind of nodes can be displayed in the menu. I ended the name of my node with ‘builder’, and it successfully appeared in the menu.

Regarding ‘nodeFlag’, I use Python in ‘OnCreate’ to control it.

This may not be the best solution, but it has indeed solved some problems.

Yeah very cool, does seem to work. Missed the big note at top of docs for 20.0 update

. Additionally if you right click 'Tab Menu Mask', can set 'Make current value Default' for custom additions. Works for in-project as far
