Hello,

Is it possible to build and bake a tool from CPP in a blocking function?
I'm trying to automatize the pipeline of my houdini tools. To do that i need function in Cpp/BluePrint/Python that freeze the current Thread.

Thanks,

Hi,

Cooking in the UE4 plugin was specifically made to be asynchronous, so there is no way of getting a blocking cook “out of the box” with the plugin.

If you want a blocking cook, that's something you'll need to add yourself:
- use the FHoudiniAPI::CookNode function using the HDA's node ID to start a cook.
- then iterate in a blocking loop on the result of FHoudiniAPi::GetStatus()
do not exit until you get one of the HAPI_READY return value.

You'll find a little more info on that in the Houdini Engine docs:
