Hi,

PCG was indeed added in a very early state in 5.3 by Epic - but has received significant changes since.

Our support for PCG was only added for UE5.5 and onwards in H21.0.
Any prior versions of UE should use the non-PCG versions of the plugin.

Hi,

We only support the latest two versions of Unreal - so at the moment, Houdini ships with binaries for 5.7/5.6.
You cannot use binaries built for either 5.6/5.7 with UE5.5 - the only way would be to build the plugin from source.

If you can't build from source - you should use an older version of Houdini that shipped with the UE5.5 plugin.
It seems that H21.0.512 was the last one that had UE5.5 binaries for windows.

Hi,

Yes, the plugin supports per-instance custom data, you'll first want to set their number via:
i@unreal_num_custom_floats = X;
then set the values with
f@unreal_per_instance_custom_data0 = YYY;
...
f@unreal_per_instance_custom_dataX = ZZZ;
