I am reposting this message to the realtime category:
I am wondering if anyone else is having this problem?
I am using Houdini 18.5.696 with UE4.26.2.
Ocassionaly, but not allways, Houdini Engine fails to "Rebuild" the asset after I saved it from Houdini.
When it fails I get an error that looks something like this in UE4:
LogHoudiniEngine: HAPI Asynchronous Destruction Started for . AssetId = 0
LogHoudiniEngine: HAPI Asynchronous Instantiation Started for collision_prep_2: Asset=Sop/collision_prep, HoudiniAsset = 0x3ea9b9a0
LogHoudiniEngine: collision_prep_2 FinishedInstantiation.
LogHoudiniEngine: HAPI Asynchronous Cooking Started for collision_prep_2., AssetId = 0
LogHoudiniEngine: collision_prep_2 FinishedCooking with fatal errors - aborting.
LogHoudiniEngine: HAPI Asynchronous Destruction Started for . AssetId = 3
LogHoudiniEngine: HAPI Asynchronous Instantiation Started for collision_prep_2: Asset=Sop/collision_prep, HoudiniAsset = 0x3ea9b9a0
LogHoudiniEngine: collision_prep_2 FinishedInstantiation.
LogHoudiniEngine: HAPI Asynchronous Cooking Started for collision_prep_2., AssetId = 3
LogHoudiniEngine: collision_prep_2 FinishedCooking with fatal errors - aborting.
However, when it successfully rebuilds I get an outout that reads:
LogHoudiniEngine: HAPI Asynchronous Destruction Started for . AssetId = 11
LogHoudiniEngine: HAPI Asynchronous Instantiation Started for collision_prep_2: Asset=Sop/collision_prep, HoudiniAsset = 0x3ea9b9a0
LogHoudiniEngine: collision_prep_2 FinishedInstantiation.
LogHoudiniEngine: HAPI Asynchronous Cooking Started for collision_prep_2., AssetId = 11
LogHoudiniEngine: collision_prep_2 FinishedCooking.

Mind you nothing changed between the success and the failure. Sometimes the rebuild succeeds after hitting rebuild a few times, sometimes not. The asset always rebuilds after failure after exiting and going back into the same UE4 session.
I first notices this problem with UE5. However, since the software is not yet released I chalked it up to pre-release bugs. But when I started getting the same behavior in 4.26.2, I started to suspect 18.5.696.
Any insight to the source of this behavior would be very helpful!
