I believe it's because you need to manually create any directory(ies) you are writing to before rendering.
The Karma ROP doesn't have an auto-create subdirs toggle yet…

Hi,
It appears that the Substance plugins are just for Windows at the moment. Any ETA on the Linux versions? Obviously one of Substances big selling points is that it works on Linux

I just tested this with mwnorrie, and it works fine in a vanilla Mantra ROP, but in a DNEG tainted Mantra ROP it fails.
So… it's a DNEG problem

We use Quadro at work, so for super crazy heavy geo they're good but if it's for home or casual use, GTX are fine. More system RAM and more GPU RAM also helpful.

Yeah that laptop will run Houdini fine, but system RAM will be the biggest factor restricting you. GPU doesn't matter that much, I use a gtx960m and Houdini works great.

I can only speak for myself, but to me the most exciting part of LOPs/Karma is that you have the full power of Houdini behind it.
I've used Clarisse and I know something of Katana, and the biggest problems with both those apps is that to fix many things you need to export from another DCC (maya, houdini, whatever). With LOPs, for the first time, is a lighting package that is truly a one-stop-shop.
I can't wait
I hope SESI don't cripple LOPs by offering it without SOPs, COPs, CHOPs and the other things that will make LOPs an outstandingly powerful lighting package.
I certainly can't comment on SESI's plans for pricing with Indie etc, but compared to Clarisse and Katana, LOPs in Houdini Core (Escape etc) is crazy cheap, as both those apps are around $8k per seat to get only 1/10th of what Houdini offers. It's incredibly good value.

Could you store the deltas on the node's Python data dict itself? Then no need editable nodes, which usually cause problems unless it's part of a specific artist workflow.

OK nevermind, I had $HOME/houdini17.5/houdini.env that looks like was set up by the GameDev toolset or something. It seems to have broken everything. I've removed that and all is well.

Yes, it's a very longstanding problem that causes a lot of extra dev work unfortunately It would be amazing if it was fixed someday.

Render times are super basic. Render your image at a low res, and then calculate how many times bigger the final image will be. Each time you double the res, it takes 4x longer (approximately! since rare is the image that is square) minus the initial startup time which stays approximately the same.
So, you render at 320x200 resolution. The setup time takes 1 minute (let's say) and the final render takes 2 minutes (let's say).
So if your final render is 2560x1600, then:
320x2x2x2 means final time of 2 minute X4 x4 X4 or 128 minutes. Plus 1 more minute for the setup time.
All approximate of course but gives you a decent idea.
There is no render engine that can estimate even vaguely a render time without having rendered the image at least once. That I'm aware of! If there is, I would love to know about it.

Hi Paul,
I just noticed this created in $HIH:
\tmp\AV_Cache\testApple
However I'm on Linux so… I'm guessing some Windows-specific code snuck in?
That's created as a single directory. Also given how big that could potentially be, is $HOME/houdini17.5 the best place for it? Why not $TEMP? I could be missing something though.

PDG » RFE: DnD parms into Wedge TOPs

Hi,
Currently there is no easy way to get parms into a Wedge TOP other than doing a Drag and Drop and choosing “Absolute reference” then manually editing out the expression bits. The Parm chooser dialog is waaaay too slow in a file with 100's of nodes and many parms on each node.
RFE: Please add a new DnD “drop” action “Parm Path” that simply types in the path to the parm.

Seems to work now thanks!
I do notice that if I use the Orient parameter from the Torus (as an example) and use its String value (i.e. x, y, z) I will get errors on the Wedge node:
The Int version of that parm works though.
Calling parm.set(“x”) etc does work, so not sure why it's failing.
I do see where “bad” data could be entered in the Wedge top though when wedging strings, perhaps this could be a little more artist friendly if that happens?

Hi,
Giving it a try! However, I can't make it work or I don't understand… Please see video for trivial example.
Also, the attached .hip throws up a Python error when I try to restore a String wedge.

“It depends”
If you're using Houdini exclusively, then basically any modern Linux distro will work, as Side Effects are easily the best since Houdini works on almost every Linux I've ever tried.
Are you a technical person? If not, you may find OpenSUSE or Ubuntu easier to deal with setting things up. I recommend Kubuntu over Ubuntu since Ubuntu only has the Gnome desktop which is (personal opinion) crap.
If you use other software such as Maya, Substance Painter/Designer, then you should likely stick closer to an RPM based Linux distro, which means OpenSUSE, Centos 7 (or higher) and others. You can get Maya etc to work on non RPM based systems but you'll start to get technical and it can be frustrating if you prefer making images over running command line scripts
If you're on a Laptop I definitely recommend Kubuntu or Ubuntu, as it's the best I've found for laptops. It even supports the Intel/Nvidia hybrid cards. Again, if you're technical and don't mind spending a lot of time on tech setup, you might be able to get other distros to work on the laptop.
I'd say just as important as the distro is the graphics card. There is only one choice for Linux: Nvidia for better or worse. The drivers “just work” and with OpenSUSE and Kubuntu (and probably others) you just install them and away you go.
Hope that helps!
