Ok, so I can tell by the Optix readout in the first image, that the GPU has not run out of memory.
We have already improved XPU glass for the next version of Houdini.
Is it possible for you could post a version of this scene I could use for testing?
Thanks!

I do have to say that reading this thread I’m amazed at the level of Client interactions and support that SideFX provides! AMAZING!

A camera sequencer similar or better than the one in maya.

my H20 expectation list:
tutorials, tutorials,and tutorials and courses, and especially recent ones, to learn Houdini correctly.
Notably to learn how to use karma...
and maybe an evolution of modeling tools, so that people use houdini for modeling and not just VFX.

Sculpting is becoming MORE important to contemporary workflows

an OSL shading node such as Code Snippet is nice.

In material context press the tab and type OSL, you will see a node like a snippet for the OSL.
Isn't it what you want?

Lots of good ideas. Here's my take: I'd be happy if XPU were to be hardware-agnostic, and not locked in to a singular certain manufacturer.

If Renderman XPU development, which is developed intentend to be hardware agnostic, is an indication of anything, we may not see Karma XPU on AMD GPUs for maybe 5 more years? Personally I would like their resources devoted to optimize, implement QOL features and improve performance better than hardware agnosticism and that's coming from somewhere who after decades on Mac decided to build his own PC in order to get the best out of 3D apps. But I get your point and Mac users may be pissed off.

make Karma/ Mantra convert textures to .rat on the fly and use it just like Arnold. I think Arnold is the best in tersm of .tx files generation since I dont need to manually enter ".tx" at the end of every jpg on every single shader.

big hassle for big scenes with alot of megascans assets

% hconfig -h HOUDINI_TEXTURE_DISK_CACHE
HOUDINI_TEXTURE_DISK_CACHE
Some image formats will have better performance when used as texture
maps when rendering. The imaketx program can be used to create these
high-performance texture files. This variable controls how non-ideal
texture maps should be used for texturing, automatically running
imaketex on these images to create high-performance texture files. This
conversion is done once, resulting an overall performance increase.

  * Unset or native: will use the raw texture map with no conversion

  * local will create a high performance texture file in the same
    directory as the source texture (if possible).

  * temp will use a local disk cache to store the high performance
    texture files. This cache can be controlled using the htexcache
    command line utility.

  * all will first try to create a local texture file and if that fails,
    it will fall back to the temp disk cache. For example, a texture
    file $HIP/maps/color.png would have a local texture file created in
    $HIP/maps/color.rat, but a texture stored in an HDA cannot have a
    local texture created, so a cached file would be created in the temp
    disk cache.

This was added in H19.5:

Comparing Blender and Houdini UX makes no sense.
Houdini is more of an IDE mixed with a DCC rather than pure DCC and in it nodes are laid out in a unix filesystem fashion (hence the "nodepath", attr, slot format).

(assuming you use an external code editor for wrangles)

Sure. But could Houdini learn from other software? Yes. Could Houdini be more user friendly? Hell yes.

drew
The other question to ask here is could Blender's UI be extended to provide the vastly more complex and deep functionality of Houdini and still be "user friendly"? I'm going to suggest the answer is no.
