UPROPERTY Help Feb. 6, 2021, 9:30 a.m.

Seems like bReceiveDecals (tried without b too) is also not supported, found it in UPrimitiveComponent? Or have someone found a way to set that off? Placing decals on walls with PDG HDA, but would set the decal not to show over windows, doors and some other pieces.

Edit: That Eetu's trick can be handy to use with UE4 editor widget to set rest of the needed values. Own roll-decimal for each settings. 0.100101011

Edit2: Nevermind, ReceiveDecals started working as uproperty.

PDG cooking is expecting files to be under UE install? Feb. 2, 2021, 6:08 p.m.

Getting this " as an expected output file, but it wasn't found when the item cooked"-error with some HDA processors used in PDG HDA when used in UE4.26.1 (v2 Houdini engine). Same PDG working normally in Houdini Editor. Having all paths set as full paths. Can Python node's in HDAs behave differently in UE4? Do the HDA need to be in 18.5 otl-folder. Using some older HDA from 17.5 (still updated). Generating point-cloud with unreal_instances for whole building, much foreach feedback loops. Probably will divide the HDA to smaller pieces if nothing else helps, wrote it too messy. Or will just generate the results this time in UE4 side and randomly bringing premade point clouds into UE4.

But any tips are welcome.

Keep World Transform not working? Feb. 1, 2021, 2:20 p.m.

Hey, is that keep world transform stored as attribute? Cant get that setting have effect when using with PDG. Only working when using only basic HDA without PDG in UE4.

Having TOP network in HDA. The HDA have a SOP input that is connected to null which is read from geometryinput inside TOPs (sop path). Would be interested know the name of that possible world transform attribute to add the offset to curves that are currently not following HoudiniAssetActor location but snapping to 0,0,0.

Having UE4 instances placed following curves, multiple curves each with own workitem. As strange thing, all items still recook when moving any of the curves. Should each curve point be own workitem or how to prevent that. Would be cool to have HoudiniUE4 tutorial for PDG curves updating only data related to the edited curve. Like in that video showing the feature in unity.
