Hint: Karma MaterialX Shader needs to applied as Subnet to the ASSH “shader”Shader” Tab.
Drag & Drop Shader/Material Builder VOPS to the Shader Tab
Hint & Because of Beta: The Houdini console logged a lot of infos whats going while the rendering via HYTHON/PDG
The automatic thumbnail generator just started for the selected renderer in the preference tab
A TOPS/PDG network is started after adding a shading network. The entry turns to a green status and will update with the final Image after its rendered. (You can add multiple VOPs at one batch)
Note: You can switch between folder while a thumbnail process is running. The process will be stopped and start again in case you enter the folder again.
Adding VOPs to a MAT context
Organize your libraries with folders and Drag&Drop shader to and from it
Add Metadata, Tags, etc.
You can also add a VOP network from the NetworkView with Right-Click. A library prompt appears but you are will not able to a specific subfolders, just the main library folder
