multiple houdini/octane versions environment vars

[WhyGee]

Hi,
Sorry if this question came up already and if it did I'd appreciate a link to the post.
What would be if possible the easiest way to setup houdini with multiple versions of octane render. I'd like to have a general "default" version, for example when rendering with deadline. And another way to specifically use a different octane release in specific projects.

Thanks alot!

Hi,

Of course, it is not possible to work with two or more Octane versions at the same time in Houdini, so you should think about some kind of launch script to configure the Houdini PATH and HOUDINI_PATH variables and select the desired Octane version, and start Houdini once these variables are set.

Thanks,

"it is NOT possible"?
I didn't mean in the same session of a houdini process, just 2 different instances of houdini running different versions. Do you have an example of such a launch script? I've tried something and I'm not sure if I did it right but it seems like the houdini.env in the user documents folder overrides whatever is in the script.

Thanks

Probably the problem is that if you are using a script to configure the environment variables, the houdini.env file must be empty (or at least it should not have the same variables that you have defined in the script).

Hope this helps,

So how could I have a default octane installation that render managers like deadline could use without the houdini.env ?

Hmm, not sure. I think that deadline has a tool to set environment variables, you could add the PATH and HOUDINI_PATH variables there to configure the render session to use any Octane build, I suppose.
