| 21.0.652 | Recipes: Removed node type validation when recipes are installed, as this validation caused Houdini to hang at startup for several minutes when assets were loaded through a network. Before this change, a recipe with missing node type would display an error in the Recipe Manager and the recipe would be set invisible in the tab menu, shelf or in any other menus. If a recipe is placed with missing node types, the Log Viewer still provides a message about the node types that could not be created. |
