Hello,

Since last production build 20.5.445, I can't open the "Layout Asset Gallery" panel.
I get this error each time I try :


Note that I'm on windows 11.
I tested on 3 different computers (all on win11), I also tested by removing my env pref, but no luck, same error.

Any idea ?
Is anyone on win11 + H20.5.445 that can tell if it works ?

Thank you,
Julien

Hello,

Some months ago I have same problem, and the solution was to uninstall "Boris" (an OFX plugin) from program file folder.

I don't know if that can help you.

Hello,

I notice shading artefacts on self shadow transition when using a "bump" node.

The fact is when I dezoom from object transition become good (cf. screenshot).



Without bump, no problem.
Using normal map instead, no problem.
Bump on redshift working good.



Does I miss something ? Is it a karma limitation ? Is it a bug ?

Thank you,
Julien

Bug replicated on "simplified" scene (still need all textures).
Mail already sended to suppport.

Hello,

Ok I go on rendering phase this weekend so I'll have probably more info about this "bug ?" recurrence soon and tell you.

For more info I rendering a big ground map composed of 107 textures of 8192 square pixels.
I'm using karma xpu.

I also notice on other frame a similar problem where small polygons and very few (2/4 primitives) don't turn black but dark like with a normal bug.
Once rerendered they became a bit more corrupted (8/9 primitives), then I triangulated and problem is gone(I hope).

I have heavy assets (like textures) but I can share you soon for more investigation.

Hello,

I'm using karma.
I have some polygon that appear black on final image rendering.
But on rerendering same frame all is good. It's not constant.




Do you already experience this kind of problem ?
Does-it have some king of thing to avoid ?
Is there some topology to avoid (triangle only needed ??).

Thank you,
Julien

Hello,

1. Subnets inside dopnets don't update the viewport properly.

Yes I also notice that just subnet inside subnet don't always update the viewport properly, really annoying..
Or when you change visibility of an object on top of hierarchy it doesn't show up until you select object at this same hierarchy level.
Or when you dive inside an instanced node object and back outside, instance still only with "point visibility" instead the instanced objects. need to move a parameter to force viewport update.

And do you also have this hud viewport bug and this message error when you save scene ?


Thanks

Hello @robp_sidefx, Ok I do it right now.

Hello,

I have multiple problems to create good thumbnail with custom scene :
1) First, thumbnail just can't be generated on actual production build H20.0.625 (error message "unable to write image:" and "Failed to create file")
I check all access and all is good but that just don't work. Anyway it works on "last" daily build H20.0.649

2) I want to generate bigger image but can't go up to 256px.
If I set to 512px or 1024px, rendered thumbnail has always clamped to 256px.

3) Now the biggest problem was when trying to render thumbnail with same look as viewport rendering color (karma xpu). Color doesn't match at all.


Can but subtle but still don't match on all variants.
After investigation I notice that in fact thumbnail was rendered and writed in ACEScg but there is no way to set "color correction" in the "asset layout gallery" pane like in viewport.

There is also no way to directly set a good ocio output color profile to match with viewport render.
How can I acheive good thumbnail to just make them true in color ?

I notice that houdini config ocio has not the "Invert ACES 1.0 SDR-video" output space, like in redshift, that allow direct conversion from ACEScg to simple flat sRGB picture (hope that's clear)


This way it would be easy to set this ouput space inside "karmarendersettings -> Image Ouput -> Output Colorspace" parameter.
The only way was in cops with an "ocio_transformview" node inside a "vopvop2filter" node. But this way make all really complicated.


Have you experience in working with usd layout asset gallery ?
How do you face to all this problems ?

cf. sample project file
Thank you

well, in the clone panel create a clone, point it to the rendersettings lop and set it to xpu. this will render into rendergallery.

Yes, same as you, wrong color.. Bug ?

ronald_a
Is that the rendering coming from a clone?

Arg ! no sorry I misunderstood this point . Tell me how you make a clone and I'll made a test on my side.

Edit : Ok I see, when I render in gallery in background, you're right color are wrong. Maybye a bug.

@ronald_a, sorry What do you mean by "cloner" ?
With render Gallery, color is matching on my side.

@ronald_a, It's works on my side after explicitly set "ACEScg" on "output color space" parameter inside the "karma render settings" node (cf. you modified scene). It override ocio settings for output.

Other option was to change your ocio profile to set correct color space that match with the kind (pattern/extension) of your output file (be carreful as it's also impact input file)
Take also care about the ouput render folders name that is used if a specific ocio pattern was found.

An "other way" was to set the pattern "ACEScg" on you your ouput file name, ex: "myBeautifullPicture_ACEScg.exr" and if "ACEScg" is already set to OCIO config as a pattern, it auto convert them to this space without doing it by override parameter.

Hope that help.

@ronald_a, do you have scene file + screenshots of what you want and what you have ?
And also a screenshot of your "OCIO editor". Perhaps it can help to help you

Hello, to continue what @jsmack said, yes ocio rules also impact output file, but you can also explicitly set ouput color space inside the "karmarendersettings" LOP node on "AOV's rendervar" tab.

Hello, I notice same thing.
On my side, in viewport, if I hit "S" to go in select mode,black bar disappear.

I also can't render anything this morning
[12:14:33] ERROR: No karma license found.

hello @jsmack,

Yes that make sense, thank you for examples.
Now I will be more careful about the names of my folders path.

Hello,

Is that normal if in project/texture path if there is a named pattern, like "//server/myBeautifulProjectACEScg/tex/myTexture.jpg", texture is altered by this ?
I tought that's only the short texture named ("myTexture.jpg") that is take into account.
It make me bugged a time before I catch this

mark
This should be consistent in the next daily build of H20.0.

Yes !
I confirm, thank you
