OTOY Forums

I can‘t add Octane in out, and Octane 3.08.1.0 is worked fine.

i add this in houdini.env

Code: Select all

PATH = "$PATH;C:/Octane_Houdini_Win64/Octane_4.00.0.8_Houdini_16.5.496_Win64/bin"
HOUDINI_PATH = "C:/Octane_Houdini_Win64/Octane_4.00.0.8_Houdini_16.5.496_Win64;&"

Hi,

Do you know if the Standalone V4 XB3 works on this system? Perhaps you have a problem related to outdated drivers or something like that. You can download the Standalone here:
viewtopic.php?f=33&t=67790

If this Octane V4 Standalone works fine, perhaps the problem is related to a mistake in any of the houdini.env PATH variable characters, but let's check first if your Octane 4 works fine on your system. If the Standalone doesn't work, please update your NVIDIA drivers to the latest ones available.

Thanks,

thanks for reply. Octane V4 Standalone works fine on my system. and I think houdini.env PATH variable is fine too. because Octane_3.08.1.0_Houdini_16.5.496_Win64 is worked fine.

Weird, I've just installed the released .496 version from the .zip file in your same folder and using your same houdini.env configuration and here all works fine. Do you have the

Code: Select all

HOUDINI_DSO_ERROR = 2

variable defined in your houdini.env file?

Thanks,

thanks again.
I add 'HOUDINI_DSO_ERROR = 2' to houdini.env file. and says that.

Hmm, what a weird issue! Do you have any other environment variable defined in the houdini.env file? I know that if Octane 3.08 works fine an error in the configuration file makes no sense, but perhaps you could attach your houdini.env file here to be sure that nothing is broken on it.

A corrupted installation could be also a remote possibility. Perhaps you could try to download the .zip file again and fully replace the plugin folder on your HD.

Thanks,

You can also replace the $PATH position in the PATH variable ... try this one:

Code: Select all

PATH = "C:/Octane_Houdini_Win64/Octane_4.00.0.8_Houdini_16.5.496_Win64/bin;$PATH"

I replace the $PATH position and it's worked! Thank you so much!

David_DK if you don't mind I join to the topic. I have the same situation, but in my case probably everything is fine in the houdini.env.
Maybe Juanjagon has a solution for my problem.

My houdini.env Look's like this:

HOUDINI_DSO_ERROR = 2

PATH = "C:/ProgramData/Redshift/bin; c:/Users/Cr_Pc/Documents/Octane/Octane_4.00.0.8_Houdini_16.5.496_Win64/bin;$PATH"
HOUDINI_PATH = "C:/ProgramData/Redshift/Plugins/Houdini/16.5.496; c:/Users/Cr_Pc/Documents/Octane/Octane_4.00.0.8_Houdini_16.5.496_Win64;&"

I have exactly the same error on the start. Standalone working.

Can you please remove the space character that you have just after the semicolon, between the two plugin paths?

Thanks,
-Juanjo
