Thanks to Matt who responded to my bug report, this was fixed by updating to the latest version.

Hi again,
I've tested this in a simplistic project with the most basic HDA (please reach out if you want the files, too heavy to upload here). The results are the same. When baking HISM (here the cone, it's got LODs) to Actor, all the instances disapear. Baking only works for ISM (here the beach balls, they don't have LODs). See the before and after images below
Before baking
After baking
I found a work around but it is quite unstable on big scenes. First I add the "unreal_foliage = 1" attribute on all my instancing points. Then I bake a first time as "foliage". Then I bake a second time as "Actor". Then I clear the instancing actors that are empty (HISM) and the redundant ones (ISM). But that's far from ideal.
I would greatly love some help and documentation on this.
The absolute best would be for SideEffects to provide simple example files for all types of export/instancing/usage of special attributes etc. and more documentation about the baking process.

Hi.
I'm trying to bake a level that contains instances. Some are Instanced Static Meshes (because the instanced mesh only has 1 LOD), others are Hierarchical Instanced Static Meshes (HISM), (because the instanced mesh has multiple LODs*)
After baking to Actor, the actors with HISM are empty: the number of instances is zero.
See attached images for reference
I really can't figure this out even after reading the help over and over. Help would be greatly appreciated.
Thank you.
I'm on Houdini 19.5.569 and UE5.1.0
*from the help help [www.sidefx.com] :InstancedStaticMeshComponent or HierarchicalInstancedStaticMeshComponent, the latter based on having LODs or unreal_hierarichal_instancer == 1

Hello,
Reading the list of supported Mac Graphics Cards below, I don't see any of the cards of MacBookPro (AMD Radeon R9 M370X) and iMac Retina 5k (AMD Radeon R9 M395) and iMac Retina 4K (Intel Iris Pro Graphics 6200).
:?
Does that mean that none of the latest Macs would run Houdini smoothly ?
I'd like to buy an iMac (preferably, or MacBookPro) for video/photo mainly but with the possibility to experiment in Houdini as well.
Thanks for the help!
That is the list by Sidefx
AMD FirePro D300, D500, D700
AMD Radeon 5770
AMD Radeon 5870
AMD Radeon 7970
Nvidia Quadro K5000
Nvidia Quadro 4000
Nvidia 650M and 750M
Intel cards are not supported on the Mac -> looks like iMac 4k is totally out of the question
