Fetch Cook Log Displays the contents of the Houdini cook log.This process cannot be reverted and should only be used with final content.īaking all or only selected Houdini Asset Actors can also be achieved via Console Commands or Keyboard Shortcuts. ![]() The new actors will be added to a new folder in the World Outliner.Īll Houdini assets present in the level can be replaced automatically by their baked counterpart by using the Bake And Replace All Houdini Assets entry in the file menu. Note that an InstancedStaticMeshComponent will spawn StaticMeshActors as well, because there is no native InstancedStaticMeshActor in Unreal. For example each StaticMeshComponent will spawn a StaticMeshActor. Bake to Actors Bakes all ouputs and then spawns new individual Unreal-native actors for each ouput.Replace with Blueprint: Does the same as Bake Blueprint and then spawns an Actor based on the new Blueprint and replaces the current HoudiniAssetActor with it in the map.uasset files and creates a new Blueprint Actor class which has components which use the baked outputs. Bake Blueprint Bakes all outputs into.uasset files based on the outputs of the asset. All unused and unreferenced assets stored in this folder can be cleaned up automatcally by using the Clean Houdini Engine Temp Folder entry in the file menu.Īssets can also be cooked or rebuilt via Console Commands or Keyboard Shortcuts. This temporary content will be stored in the Temporary Cook Folder (Game/HoudiniEngine/Temp). Some assets, mainly the one creating landscapes, or assets that create textures from a Houdini material, will need to have some of their temporary cook content written to a file. Reset Parameters Resets the asset parameters to the saved default state as specified in the Digital Asset.hda has changed or if something has gotten out of sync. hda file and forces the asset to recook even if no change has been detected. This is useful mostly when the option Enabled Cooking on Parameter Change is disabled. Recook Asset Triggers a cook of the outputs of the asset in Houdini.This happens either by a forced cook or (optionally) automatically when a parameter changes. The ouputs of the Digital Asset inside Houdini are recalculated when a cook is triggered. In the context of a HoudiniAssetActor, Cooking refers to the same concept in Houdini. Cooking Triggers Downstream Cooks When the digital asset is cooked, will trigger a cook on other digital assets for which the given asset is an input.Use Native Houdini Materials Houdini materials applied to output nodes will be marshaled to Unreal.Transform Change Triggers Cooks Translating, rotating or scaling the Asset Actor in Unreal will trigger a recook.Upload Transforms to Houdini Engine Whether or not to set the Unreal world transform on the digital asset's input node in Houdini.This may be desired for complex assets that have a long cooking time. Disabling this allows parameters to be changed without recooking the ouputs. ![]()
