Error Adding Mantra render

[Gilly123]

I'm having this issue where when I try to add a Mantra render to my scene, I get an error message.

See image attached.

 

I have some projects that had no issue with adding Mantra, but not as of late and I was not sure if updating to the latest is causing it or not.

 

Im running 15.0.347 on a i7 Hackintosh, 32gb memory, Nvidia 980ti card. Running Apprentice license.

 

Is there a procedure for adding Mantra? Like certain prerequisites that must also be in place before a Mantra PBR can be added?

Any help is GREATLY  appreciated!

It should just add without error - perhaps you have a different version of Python installed. Type the following into the terminal: /usr/bin/python

 

You can also try installing a later version Houdini.

[Gilly123]

I entered that into terminal and got this:

Python 2.7.10 (default, Jul 14 2015, 19:46:27) 

[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin

Type "help", "copyright", "credits" or "license" for more information.

That Python should work. Try the latest version of Houdini if you can, it's had ~100 days of bug fixes compared to version you have installed.

Downloading 15.0.416 (recommended for Yose)

 

Installed selecting local license.

 

Still same error.

Try throwing out the Preferences folder.

 

~/Library/Preferences/houdini/15.0

[Gilly123]

Well I was able to find the pref which were hidden. Deleted the 15.0 pref .  Houdini relaunched and still throwing the same error when adding Mantra or Mantra PBR to the scene. Maybe it's Hackintosh related issue? It's just weird how it use to work, then it doesn't. I'll try and determine if the files that have a working Mantra can be merged with one that has an issue.

[fathom]

are you creating from the main menu or are you hitting tab and then placing your mantra node that way?

[Gilly123]

I was using the drop down menu. Im re-watching/re-building a pluralsight tutorial that worked with mantra render, Intro to Particles. It's has to be something stupid silly on my own doing.

[Gilly123]

Well, I went thru the tutorial even though it was tempting to skip to the mantra lesson chapter, I didn't.

I guess that's the good news. The bad news is that I still could not add a Mantra node, plain or pbr, without getting that same error message.

So, it's got to be either how Yosemite 10.10.5 on my hackintosh is not 100% happy with running Houdini. That is unless someone has some other things to try. MPlay works fine. Yet I can go back to the same tutorial project hip file from a few months ago, and it has Mantra and renders. So I can have an older project work, but a newer version of the same content and procedure that throws that blasted error. Maybe a script is broken. Is that a viable thought? I the error seems to point to a misnaming of a node during the creation of the Mantra output node being added.

 

 used Text Wrangler to look at the two files...

so you get the same error if you browse your network view pane to "/out" and hit "tab" then locate "mantra" and place down the node?

 

the main menu method executes additional python (namely the main menu python code) so it's possible there's something wonky with that code.

 

you can try this... open a python shell inside of houdini and do the following:

import roptoolutils
roptoolutils.createRenderNode('ifd')

that will create rop the same way the main menu does.  see if it chokes and where it chokes if it does.

I did that, and this is what the python shell said:

 

>>> import roptoolutils

>>> roptoolutils.createRenderNode('ifd')

[fathom]

does it work with the tab menu? 

 

 

that is sounding like a bad install of something somewhere... or a bad path, maybe.

 

try this in a python shell:

 

hou.node("/out").createNode("ifd")

[Gilly123]

Might be time to try re-installing Again, Houdini throws the same error back after entering the script into the python shell:

 

Type "help", "copyright", "credits" or "license" for more information.

>>> hou.node("/out").createNode("ifd")

[fathom]

okay, so try this in an hscript window:

cd /out
opadd

 

that should list all the available ops you can add under the /out path.

 

opadd ifd myNode

 

will add a mantra rop called myNode

[fathom]

do you only have this problem with mantra nodes?  can you place a renderman rop?  how about vops?  like say a transform vop?

 

these all come from the same hda:

 

in the houdini/otls dir in your install, there's a file called "OPlibScripted.hda".  that's where the ifd driver node is located.  see if you can locate it.

 

you can try using the "assets" menu and opening the "manage asset libraries" dialog.  that should list all the otls installed (including the built-in nodes).  in the "scanned asset library directories" tree you should have a dozen or so libraries coming from your houdini install.  it could be those are unreadable or corrupted or something....

[Gilly123]

The Mac is not playing fair with having the files searchable on my system. This is what Im seeing in the image attached. I tried your previous post as well, which did not work either. 

[fathom]

in houdini, use the "assets" pulldown on the menu bar.  then select "manage assets library".  that should help you locate where in the file system the files are located and perhaps identify a problem (like it's empty).

 

the Oplib*.hda files should be in  "/Library/Frameworks/Houdini.framework/Versions/15.0.416/Resources/houdini/otls" i'm guessing (not sitting at a mac).

[Gilly123]

The mantra assets seem to be there. Found them with your path info from above. Reinstalling did not fix anything. Opening the working mantra project, works. Creating a new one from fresh assets, does not.

 

Perhaps I am not clearing out all the preferences to start fresh from the install. Since once I install, houdini know where recent projects are. I thought I had tried ridding the preferences once already. Possibly fresh install with all preferences purged. I'm at a loss. Are there pointers as to where all the install items live, so I can manually delete all files? Or perhaps some default setting is point to an empty or wrong location?

 

I really appreciate the comments and would much rather be lurking on threads rather than learning the finer points of un-breaking an install problem.
