Hi.
Afanasy render script just want to render node but it fails "_hou.RopNode_render(*args, **kwargs)".
There can be lots of reasons, that dos not connected to Afanasy.
For example you will see the same error, if camera lens is zero.

Can you give full task output from the very beginning to the end.

Hoping this may be enough to tack where problems are....

Please guide for any possible changes to forward to Houdini team

OR else possible changes which can requires to our AFANASY setup IF ANY

Please guide us possible reasons,

Thanks for approach

This can be not related to your issue.
But why your Houdini uses python2.6?
For a very long time Houdini uses python2.7.
And may be afanasy ROP Python code even not compatible with 2.6 (i have not tried).

Thanks timurhai

I will try to check to upgrade python 2.7 if possible

Can you tel me what can be do if we wants keep using PY 2.6

Hi.
Launch task command simple in a terminal (w/o afanasy-afrender).
If command will finish with success, (less probably) i dont know, may be some permissions problem, try to launch command within the same environment as afrender (user).
Try to modify opt/cgru/plugins/houdini/hrender_af.py somehow.
You should find out what is wrong with that line:
https://github.com/CGRU/cgru/blob/maste ... af.py#L257
Try to execute ropnode.render() function with some other arguments.

We see manta command output in your task output.
This means that mantra was executed from ropnode.render(), and something wrong was in mantra process.
Most probably it is not an afanasy problem at all.
May be mantra has not enough permissions to create a file under the user that afrender runs, or load some lib.
