Plugin cook the same data unless rebuild April 12, 2023, 6:05 p.m.


That's actually expected as the plugin doesn't check for changes on asset in the content browser.
(the issue would be similar for Static Meshes in a geometry input).

This will be addressed soon by a change that will add allow you to only refresh a single input.
(which at least, prevents resending all the other input's data)

houdini engine Unreal (hengine_noswap) option April 12, 2023, 1:14 p.m.


In the type properties dialog, select the Vector3 parameter you want to enable noswap for.
At the bottom right, you'll find tags.
Click on the + button to create a new tag, name it hengine_noswap, and set its value to 1.
Apply the changes, save the hda.

In unreal, changing the Y value of the parameter will also change the Y value in H, same for the Z value.

Sidefx Labs for UE5.1 April 12, 2023, 1:04 p.m.


If you're referring to the Houdini Engine plugin, we've been supporting 5.1 (and now also 5.2) for a while now.
We generally support new versions of UE a few days after the offical release.

What has changed with UE5 however, is that we now use the same source code for all UE5 versions (to limit the amount of backport that we need to do for each commit in the plugin).
So there will be no 5.1 / 5.2 / 5.3 branches on git for now, as indicated by the first line on the git repo:

"The source code in this branch is intended to be used with Unreal Engine 5.0 and 5.1"

and the release page on git also has binaries for the newer versions of UE:
https://github.com/sideeffects/HoudiniEngineForUnreal/releases/tag/v2.0.17 [github.com]

and so does your Houdini install.

For the SideFX Labs issues mentionned above, have you submitted bugs for these?
That's the best way to inform the Labs team of an issue with one of their tool.
