They do render as a png with alpha here.

If you want to see the alpha channel in mplay press the alpha channel button below the image (or hotkey 4).

You have the render rop Override Output image set to "ip", which will send the renders to Mplay and will not save them to the directory you specified in the settings node. If you want the files on disk (other than wherever mplay caches them) you would then need to save them from the Mplay menu bar.

Instead of that you may want to scroll down a bit to the husk > monitor > enable mplay monitor, that way if you hit render to disk the files will actually be saved where you wanted them, but mplay will monitor the render.


Also, you may want to take a look at your project directory structure.

Where you see $HIP in a save or load path, that is a reference to the location of the current hip file, so houdini is looking to save your output image in a subdirectory /Documents/blender projects/Goofertons projects/houdini projects/snowman/ located next to your hip file, (not in your users documents folder, which you may be expecting.)

I think apprentice licenses have to renew monthly, are you able to render a cube or something in a test scene? If so it doesn't sound like licensing.

If I open the file as is and render to mplay it renders without errors an empty scene with the sky background (though there are some warnings in the log viewer.) If I turn off the layer save path you have set on the two geometry import nodes ($HIP/Documents/blender projects/Goofertons projects/houdini projects/rgwASRBRVS etc) then it renders with the snowman and wall. Do those directories exist on your system?

The only bidirectional capable path tracer for houdini that comes to mind is Renderman.

If you open an NC file in Indie the session will be downgraded to an Apprentice session and can no longer save in Indie (LC) format until you restart Houdini.

Sidefx explicitly offers a one-time conversion of NC/LC files to full commercial when purchasing a license (files have to be sent to Sidefx), but a quick google doesn't turn up an equivalent for NC to LC.

You should email sidefx support for a definitive answer.

Perhaps this is what you are looking for?

by default it doesn't appear in the tab menu in materialx builder only in karma material builder but it does seem to work in a materialx network with xpu if you paste it in.

I don’t know enough to give you a really good answer but since no-one else has answered in months I will chime in.

Vex will not work at all with Karma XPU/MaterialX.

I am not clear on why you don’t use the built in houdinioceanprocedural, but if you want to roll your own you might try diving into it down through the nodes until you get to the mtlxstandardsurface that shades the ocean. There may be something there you can use.

I got a macbook in June and have experienced similar issues, which I do not encounter on linux.

According to:

https://www.sidefx.com/products/compare/ [www.sidefx.com]

third party render engines work with the Educational license. (ie one provided through your school.)

Houdini Apprentice is not an Educational license. Third party renderers do not work with Apprentice.

If you want to be clear about your specific situation you should email sidefx directly.

You can find Indie faqs here:

You can't use Houdini(Interface) on both machines at once, but you can set up a render farm using Hqueue with up to 3 nodes with Houdini engine and Karma/Mantra licenses.

XPU + Optix is working for me in 20.0.653 on Linux Mint with Nvidia driver 535.171.04.

It would be nice, but from the docs:

"The ocean materials make extensive use of VEX and will therefore work with Karma CPU only."

I think you will find Maya Indie will only render in Arnold within the Maya GUI. You can't even command line or batch render Maya files with it. You would have to buy a separate Arnold license to use with Houdini.

The installer has a menu item to import installations already present on your computer.

Is there any way to make modeler work inside a sopcreate network in the stage context?

19.5 runs fine on Mint 21/Cinnamon. If you use the Launcher to install you may have to manually install fonts or the Launcher interface may be blank.

Works on H19, but H19.5 Modeler pane is white with error message:

There is an error in the Modeler script.

Traceback (most recent call last):
File "/home/john/houdini19.5/modeler/python_panels/modeler.pypanel", line 1, in

File "/opt/hfs19.5.347/python/lib/python3.9/site-packages-forced/shiboken2/files.dir/shibokensupport/__feature__.py", line 142, in _import
return original_import(name, *args, **kwargs)
ModuleNotFoundError: No module named 'modeler'






??Perhaps not compatible with H19.5 python version?

I'm running 18.5.532 python3 build on Linux Mint, bridge seems to work just fine for both mantra and octane so far.

Does this work with the Python3 builds of Houdini?

Hi, there is a bit of information here from a sidefx staff member about configuration of mixed linux and windows/UNC hqueue:

https://www.sidefx.com/forum/topic/51988/?page=1#post-234276 [www.sidefx.com]

You might consider emailing sidefx support directly, forum replies might be a bit random. Support was very good when I had trouble setting up the first time.
