Yaniv Gorali on the Houdini Artists facebook suggested this solution (attachment). The Karma AOV VOP (inside karma material builder) also creates Render Var automatically, cool!
Thank you very much buddy!
I didn't know that approach. (Sorry for cross posting but I was a bit desperate after few days).

@jsmack thank you very much!
If I set Specular of the material to zero, then Albedo is not "contaminated".
(USD Preview Surface still contains a tiny bit of "fresnel" at sharp angle)
(MTLX Standard Surface seems to be clean, even at sharp angle)
I don't feel competent to RFE or bother support, as I am new into this.
I have tried to set up my own AOV (as in the picture) but that behaves the same as Albedo (with all the issues described above)

@jsmack Thank you for bearing with me!
Is it a bug then?
Can I define my "own" albedo aov in Karma XPU?

@jsmack thank you very much for your answer. Yes I want kind of "background plate render". I want the "raw" unlit colors of an object texture (and composite the shadows afterwards). I could do that with a second render (texture set as Emmision Color).
I thought that Albedo might be what I need. I am really a beginner, please apologize my silly questions:
- why aren't the textures in the picture (1.2.3.) all the same and "raw"?
- texture is set as Base Color
- it is an Albedo pass, there is no light in the scene

Could you please help me with the AOV settings I will need for the result on the picture B? I am AOV+Comp beginner, so please excuse my possibly wrong terminology.
What I want in the end:
spheres - rendered as default
box - I would like material with texture, and to have "original texture colors" (as original as possible) available in comp
I don't want to ask for too much complexity with colorspaces and numerical values. The result is to be used in videomapping on a building, so a "simple" solution is perfect for me.
- I think, that I need a Direct Emission AOV, but without the emmision actually affecting the render.
- Or is there some "UNLIT" Diffuse or Beauty AOV in Karma XPU?

You could add a Shelf tool with this python script, and add a Hotkey to that tool:
Definition of that function is here:
C:\Program Files\Side Effects Software\Houdini 20.5.299\houdini\python3.11libs\nodegraphutils.py
import nodegraphutils nodegraphutils.reconnectAroundItems(hou.selectedNodes(), False)
Definition of that function is here:
C:\Program Files\Side Effects Software\Houdini 20.5.299\houdini\python3.11libs\nodegraphutils.py
def reconnectAroundItems(items, update_unpinned_dots, single_input_to_disconnect = None, editor = None): conns = getExternalConnections(items) replacements = getReplacementConnections(conns, items) with hou.undos.group('Reconnect around items', editor): # If requested, only delete the first connection to the specified # input item. if single_input_to_disconnect is not None: conns = list(conn for conn in conns if conn.inputItem() in items or (conn.outputItem() == single_input_to_disconnect and conn.inputIndex() == 0)) deleteConnections(conns, update_unpinned_dots, editor=editor) for replacement in replacements: replacement.createConnection()

I watched my GPU and CPU usage. CPU goes to some 11% (probably single core full load). GPU goes to 70-90%
Single core performance of that i9 may be 60% higher than Ryzen's. I am not sure where else might be the difference. Maybe try to update the nvidia drivers too. (I have the Studio Drivers 560.70)

Hi 9of9, I am not sure if I am doing this right, but I have tried this:
- open the file as it is
- set the display flag to /obj/Texture_Mask_Paint/merge1
- set the brush to Erase on the /obj/Texture_Mask_Paint/texturemaskpaint1
- hit Enter in the viewport to start the Paint tool
- (for some reason the painting transform is reversed, but I don't investigate)
I am getting ~4 fps, as in the gif
My specs:
- gpu: 4090
- cpu: intel i9-12900K
- windows 11
- nvidia drivers: 560.70
If you want to reach support, I can give them my Houdini_Info.txt file (Help>About>Details)

Here are the examples of the search. With the asterisk in the context filter, it searches for text or a hotkey.

I have tried the importV1KeymapBindingsToKeymapFile command as you suggested and got this error from line 260:
if dst_keymap_name and impl.name_token in keymap:
NameError: name 'impl' is not defined
So I have added these four lines into the function definition just to try it:
Then I got no errors. I have exported the new keymap2 file and some of the hotkeys were indeed imported.
However many hotkeys were not imported (many of them are hotkeys to shelf tools). I have attached my h20.keymap file and I will also send a Bug/RFE.

I have over 300 hotkey overrides.
(some of them are assignments, some of them were automatic "un-assignments" of default hotkeys)
Thank you guys for the information. I hope there will be some way to convert them from 20 to 20.5

I would like to take this opportunity to thank developers for using colors in many places because they have meaning and increase the clarity of the UI (to find something quick at the first sight). I also appreciate that the UI is not too flat, because using gradients in the right places also increases clarity ... same reason, to see the state (one of many states) of an UI element at the first sight (one of them being with 90's gradient is really good, why not). And of course thanks for constant improvement of the UI and UX, which is really great I think.
I attach an example of different colors (different states) of the Parm. There are probably even more colors/states and all have its importance and reason for an experienced user (it is an older image, I believe there was yellowish for a Parm with a function but without keyframe, there is also dotted outline for an evaluated expression/python/...).

Please, what are the hotkey combinations and rules for the MMB copy paste? For example in the Attribute Wrangle.
I believe these originate from Linux, there is something happening which I don't understand
sometimes the content of the clipboard doubles up.
