Hey, I just want to say that this still doesn't seem to work as it did in older versions of houdini. We don't use ACES here, maybe it works with ACES (as stated above). But when I load a simple sRGB to pick colors it is impossible to get the right values and I think I tried every possible combination available (logical and nonsense settings, just to be sure).
Should this be an RFE or a bug report? Anyone else using this without acceptable results?

Maybe I am wrong, but I think Houdini is the wrong tool for this "manually enter values" approach. (Please proof me wrong!)
You can always open a wrangle-SOP and type something like:
Or if you have a clean text file with your values you can import via python-SOP and set your positions there.
Not sure if this helps you ...

Just as addendum, heres the workaround in the wrangle "blendP" if you enumerate "id" before the split:
int newPtnum = findattribval(1, "point", "id", @id); @P = lerp(@P, point(1, "P", newPtnum), chf("blend"));

Hi,
I encountered an issue and I am not sure whats going on. If I enable a remesh and put a for-each on connectivity (class attribute) SOP after it the point numbers get scrambled. The strange thing is that this dosn't seem to happen on the basic default sphere mesh, only if I remesh it before the loop.
Can someone say if this is normal behaviour or give me a hint on how to avoid this? I have a scene in production and I stumbled across this. Right now I try to fix it with an enumerate and findattribval, but it seems not to be normal behaviour.
Demo-Scene attached.
Thanks in advance!

Hello,
yeah, it seems to be incorrect. I used this feature a lot, so I'm looking forward to the fix. Thanks for looking into it and confirm my observations. Does anyone know if there is an RFE already?

Hello,
I am facing some issues with the color picker in 18.5. There seem to be some changes in the 18.5 version, and I am not able to get the results I used to get in Houdini 18. If I try to pick color from an image (mostly Jpg/Png in my case) I always get different results, compared to the previous version. I tried all kind of settings from the drop down menu, but nothing seems to work.
Does anyone know which settings give the same result as the older version of Houdini?
Thanks

Hi bonsak,
thanks for looking into this!
“hconfig” doesn't give all the variables on my computer, but the Windows -> Shell hint was the right thing to do. If I type “set” there all the variables appear. Everything I defined in my houdini.env and all the others I wanted to see.
Many thanks, that helped me a lot.

Hello,
is it possible to get a list of all the variables that are in my actual houdini?
Because someone (Pablo) at the houdini discord helped me to find a variable named “$HOUDINI_OS” which gives the actual OS Houdini is running on. Even now, that I know this variable exists (and works) I am not able to get any information about it or any other variables that might exist in Houdini I am not aware of. If I set TMP = “/opt/path/bla/” in my houdini.env “$TMP” works fine, but I don´t know how to see these variables in houdini. “set” and “setenv” in the texteditor just seem to give a couple of common variables but not all that are working.
Thanks

I would promote the area attribute to detail and choose max. Than you can refer to that maximum value within the blast SOP.

The solution was to insert:
LC_ALL=en_US.UTF-8
in the houdini env. Might have been a language issue.
Solved.

Hello,
I'm switching to Houdini and Kubuntu atm but I am having some issues which I am not able to resolve.
Every time I click the “?” to open the help for a node an error popup appears. Also this error won't close and reopens endlessly so that I have to restart Houdini. Does anyone know where this comes from or why it happens?
Also my grid snapping for the network view won't work, but that's probably another topic …
Thanks!

Hello,
I found the answer ins Matt Estelas Wiki. No Sop-Solver needed, just set the primintinsic “”transform" and set @id = -1. This forces the objects to recalculate the collision geometry in every step.

Hello,
I tried to grow some cubes (packed geo) in a SOP-Solver in DOP, but it doesn't seem to work that way. The geometry is growing, and the guide geometry too (kind of). But it is not behaving, like I would have expected. Attached you find the simple setup, and also some screenshots.
Any advice why this isn't working
or how to grow the boxes so that they collide properly?
thx!
edit: doesnt matter for now, but I fixed the wrangle for the primS to:

Houdini Learning Materials » Poly extrude along curve
- Xue_Yue

Thanks, yes that sweep works well.
I just wondered why it is now so different than in the tutorial (there the geo was definitely on the curve).
There must have been some changes to the polyextrude node, and I wanted to understand what it is. Because I would think that it should behave like your sweep-setup. The odd scaling/translating doesn't really make sense to me and renders the “extrude along curve” pretty much useless for most cases, right?
Cheers!

Hi there,
I was following this tutorial https://vimeo.com/142470680 [vimeo.com] but the extrude just doesn't behave like in the video. The extruded object seems to be in the right shape (except the start), but in a different scale/rotation/position. What am I missing? This should be super straight forward, right? Sorry if this has been answered before.
a placed box, the curve. selected face is 3.
The resulting gemoetry doesn't match the curve.
Attached you'll find the simple scene file, but its essentially the exact same steps than in the movie.
Thanks!
