Hello, was wondering when you will have plugin for UE 5.5 ready. Thank you

Hi,
The current plugin source code is already compatible with 5.5, but you'd need to build the plugin from source.
As for 5.5 binaries, we'll hopefully have them soon.
Epic has decided to bump the compiler version on Windows for 5.5, so it's taking a little longer than usual
since we can't simply update the compiler on our build machines for a version of Houdini that's already in production.
We'll have a look at Mac binaries once we've sorted the issue on Windows.

Hi,
@Morphtek: We just tried on our end and the binaries that ship with the daily build worked fine on multiple windows machine for us.
How did you copy the Houdini Engine plugin ? did you use the old installer or the launcher ?
Was the plugin installed in the engine's plugins folder or the project's plugins folder ?

my bad i didnt explain properly it doesnt work with a c++ unreal project ,the regular blueprint based project works fine
do we need to build from source , to get it to be compatible with the ue5.5 c++ project ?

Hi, I tried to install the Houdini plugin for Unreal 5.5.4, but it shows this message when I open a project.

In the *C:\Program Files\Side Effects Software\Houdini Engine\Unreal folder*, I can only see the newest Unreal version, but not the 5.5 one.


I copied the file to *C:\Program Files\Epic Games\UE_5.5\Engine\Plugins\Runtime*

Hi, sorry for the confusion, this is how the plugin used to need to be installed. It is now project based, which allows for more flexibility with teams with different projects and Unreal/Houdini versions. So you could grab the 'HoudiniEngine' folder in 5.6 and copy it into your projects Plugin folder. You can make the folder if it doesn't exist.
Example location "../Documents/Unrealprojects/MyProject/Plugins/**HoudiniEngine**" or wherever your project lives. Then reopen the project and give it a shot. I think that will do the trick.
