URGENT !! VRAY5 Renders are write protected

[ghiom3d]

hello, after i start and cancel an IPR , the render button do nothing.


VRAY5 release on Ubuntu 20.10 up to date Houdini 18.5.351

I look at log and see thats the EXR previously rendered with Vray and HQUEUE are write protected.



V-Ray: Cannot create output image file "/mnt/DISKF/WORK_E/Bijoux/HoudiniProjects/Hera/render/RENDUS_V5/ToietMoi_H0049__1.EXR": Permission denied (13)


If i look the files i see a lock on the icons.

I remember Vray installer ask for admin password when installing..this is typicaly an issue due to installing a software with admin in Linux.

I use HQUEUE setup like you suggest in doc.

It's only happen when i use HQUEUE.
I haven't seen this usse with Vray4

Hey ghiom3d ,

I'll check as soon as possible on our end - meanwhile could you please go to the Houdini installation folder, which by default should be in:

cd /opt/hfs18.5.351

To initialzie the environment for the opened terminal so Houdini can find all dependencies, you should then:

source houdini_setup

You can then call:

hython

At this point you should be in a hython session.

You can open your file with

hou.hipFile.load("/path/to/file")

You can then attempt to render one of the V-Ray Renderer ROPs by (assuming the node is in /out and the name is Perpetuel_H0042:

hou.node('/out/Perpetuel_H0042').render()

Does that work ? Are the same error messages about incorrect permissions still present ?

Could you also please try exporting a simple cube as an alembic to the exact same path ( of course, replace .EXR with .abc):

"/mnt/DISKF/WORK_E/Bijoux/HoudiniProjects/Hera/render/RENDUS_V5/ToietMoi_H0049__1.EXR

Best regards!
