Hi Graham,
Sorry for the late reply, unfortunately I'm not an expert with the Vertex Animation tools,
but may I suggest that you post your question on the Houdini for Realtime forum [www.sidefx.com]?
You're more likely to get an answer on this there!

Houdini Engine for Unreal » Install problem UE4 4.19 and Houdini Engine

Hi Samuel,
I guess you're using the installed version of UE4.19, and are not compiling it from source?
The Houdini Engine plugin on the github is only the sources, there are no binaries for it, so you need to build it with unreal engine.
If you're not building Unreal from sources, I suggest you install the latest 16.5, as the plug-in in the houdini installer comes with the binaries, so doesnt need to be built.
Let me know if that solved your issue!

Yes,
You should normally be able to move the Handle's gizmo around, and this should update the corresponding parameter in Houdini. If it doesn't, then there might be something wrong with how you set it up.

Hi,
Sorry about that, I forgot about the 30 days trial.
What OS / Houdini Version are you using ?
And where is Houdini installed on your machine?

Hi,
You can probably achieve this via the use of transform handles:

Hi,
To get those object path inputs, all you have to do is to create an object merge node, and simply expose its “object1” (objpath1) parameter on the HDA.
When instantiated in Unreal, the HDA should have the object path input available as a regular SOP input (with the input type selector etc..)
This certainly work for current/recent versions of the plugin, and also should on the 15.5 / 4.14 plug-in, but I cant tell for sure with such an old version of the plugin.

Hi,
Here's what our developer in charge of the issue replied:
I looked into the issues and it's going to take some mini re-architecting in the UI and RE code. Not safe enough to backport to 16.5. So a 17.0 only fix.
For 16.5, users can set HOUDINI_ENABLE_RETINA=0 in their environment as a workaround. The only caveat is that some of the UI may look a little less sharp on high dpi displays.

Hi,
Yeah, that “delay” is caused internally by Unreal creating the static meshes, since it does a lot of optimization on the geometry, which Unity doesn't. We added those options (cook on mouse release) to try and mitigate this.

Hi,
Unfortunately, the Houdini Engine plugins cannot be used with an apprentice license, as they require an Houdini Engine Indie / Houdini Engine license for this and apprentice doesn't have one.
That error still implies that something went wrong when copying the files over, as you should normally have had an “apprentice license” type error. But unfortunately there is not much you can do to fix this without an Engine license.

Thanks!
I think I found the issue, it seems to be caused by the assets thumbnails…
It will be fixed in tomorrow's daily build (16.5.425)
I also fixed the installer in tomorrow's daily build, so it will install the 4.19 plug-in properly.
No need to copy the files over anymore.

The logs should normally be in \Saved\Logs either in the Project folder or the “main” UE4 folder
It also seems like some crash logs are saved in:
%USERPROFILE%\AppData\Local\Microsoft\Windows\WER\ReportQueue
( diagnostics.txt, minidump.dmp and ProjectName.log)

Ok, just tested it on my side, and that asset doesn't crash for me.
It would have been surprising since it's coming from the Houdini Fundations…
Do you have any crash log for this?
How did you installed the 4.19 plugin? did you copy it manually from the Houdini/Engine folder to unreal Plugin/Runtime directory? Apparently, it seems that 16.5.424's installer has an issue and doesn't install the 4.19 plugin properly..

Hi,
That's a deliberate choice on our side, as cooking while moving the sliders would slow down the plugin considerably.
Cook curve on mouse release is only used for input curves, and not parameter changes.
That delay is not caused by Houdini's cooking or the plugin, but by Unreal taking some time to create Static Meshes.

Houdini Engine for Unreal » Geo Copied to Unreal Spline is Mis-aligned

Hi Len,
When using unreal spline components as inputs, we add additional rotation and scale information to the curve points, which are not present by default in a Houdini Curve.
This allow additional control of the curve points via the scale and rotation widget, but can have side effects…
If you dont use the added rot and scale attributes, you can simply delete them.
A little more info on this can be found here [www.sidefx.com].
