Just wanted to chime in that, I just watched the H20 Hive today, and read the APEX Docs today as well, and, on first read, APEX “clicked” for me - the order and level of detail of the APEX Docs was very well done.
Now I finally know what all those freakin lines are in the viewport! LOLOL
I’m not scared anymore and I feel comfortable approaching APEX and building my own graphs.
So, Kudos to whoever put that together - I appreciate your efforts, I know it was not easy.

After watching the H20 Hive…Solaris is looking rather attractive. There’s a lot more Pro’s than Con’s now, in terms of the technical hurdles that USD brings along with it.
SideFX has poured a ton of features into Solaris (that either dont exist, or have a lesser equivalent in SOPs).

zatlaxSiavash Tehraniyes exactly! works only in karma CPU.
Tested builds .506 and .542. For both it works in Karma CPU, but not XPU.
That's kind of a BIG detail to omit from your original report.
There are known feature gaps between CPU/XPU

Tyler hit the nail on the head there - the benefits of USD really start to shine with larger productions, where multiple people are working in a pipeline.
But that kind of flexibility has inherent complexities that small productions dont even need to get the frame(s) done.
Like, I still dont fully understand why you cant change the material on an Instance in USD (in certain scenarios), and literally dont wanna know at this point.

Houdini Learning Materials » Request for Mechanical Rigging Tutorial Series

Just to level set, my definition of mechanical rigging would be:
- Non deforming skinning (rigid mesh binding)
- Joint limits
- Driver/Driven relationships - i.e., convert forward (axial) movement of one joint into rotation of another joint.

The request for tutorials on Houdini features is expected and preferred ( so that SideFX knows where the community need is ).
The reason there is a free (non-commercial) version of Houdini aligns with the request for more tutorials - Houdini is freakin impossible to Master. LOL The learning curve for Houdini is almost completely Vertical! ROFL
For example, the new APEX system - who can explain how that thing even works, let alone how to effectively use it?
But, I digress - I dont think anyone needs to justify their request for SideFX sponsored Tutorial content on any Houdini subject - it comes with the territory.
..and speaking for myself - SideFX welcomes such request (as demonstrated by their world class Tech. Support Team), they love supporting their Customer base.

There’s also RenderMan XPU - but its so brittle, if you blink to hard it will crash to desktop - but that Denoiser - there’s nothing close to it and its temporal too.
I think once Karma XPU gets adaptive sampling and per-object sampling overrides - it will really be a great contender in the market.

Redshift and Cycles compiles all on 1st render. Vray has a button to compile all (at least it used too, before it was multithreaded). Karma compiles per-feature on-demand.
Kernels have to be recompiled with each new GPU driver install or new GPU engine install.

briansDigipiction
when I add a new node into the shader it takes quite a while before the render updates
This is the compiling of new shaders.
we've improved this a lot for H20
Any chance we can get a 'compile all' option like other GPU Engines have?
I'd rather pay that cost during Houdini install or Startup or maybe even a command line tool, for example - just some way to pay that cost one time - all at the same time.

If I start Houdini via SessionSync, everything works as expected - I get a HoudiniEngine session and the sample Curve node works - I can draw curves in the Unity viewport.
However, if I try HE - Create Session - Pipe or Socket - I get these errors and, even though I can create a sample Curve node - I don't get the expected Unity viewport ability of drawing curves.

julcaTwinSnakes007Hello,
I copied:
C:\Program Files\Side Effects Software\Houdini Engine\Unreal\19.5.605\5.1\HoudiniEngine
To:
C:\Program Files\Epic Games\UE_5.2\Engine\Plugins
I still havn't try to update to 5.2 but from the doc it says :
"For Unreal Engine 5, you must use Unreal's project directory."
cf. getting_started.html [www.sidefx.com]
Hope that help !
The "To:" directory above is literally the UE project directory - which attempts to load its Plugins folder each time UE starts up.
SOLUTION - I created a ticket with SideFX support and they responded that UE5.2 support was not added until H19.5.614
I just installed H19.5.624 and the HE5.2 plugin now loads successfully in UE5.2

I came here looking for the same.

To:
C:\Program Files\Epic Games\UE_5.2\Engine\Plugins
..and received the same plugin loading failure message as the OP and UnrealEngine does not finish loading.
edit: I'm trying to answer the question if Houdini assets come in with their attributes into the new UE5.2 PCG Blueprints. Thanks.

I assume XPU is for Nvidia only?
yup, but XPU is so brittle its almost useless - they should’ve kept it hidden and just let the AI Denoiser shine in this release.
If you blink at XPU it will crash Houdini to desktop.
