Installing multiple versions of Vray....

[MartinB]

How do I stop vray uninstalling old versions of itself when installing newer nightly builds or stable versions?

During installation it gives you the option to either uninstall the previous version or abort the installing. I don't know how we did it before but until this point we've successfully maintained several different versions fine....

On Fedora 12

Let the uninstaller start, and then cancel it. For the next SP, we will be providing a .zip archive with all the necessary files, so this will be a lot easier.

Best regards,
Vlado

I don't see how thats possible, its all command line... If I type ok at the uninstall prompt it just goes straight into deleting all the old files with no option to stop.

The problem is I can kind of get round this by always installing vray to my /tmp/ directory and then copy the files manually to the correct network location for them to be picked up by our wrapper, but then the RT renderer won't work (the vray stand-alone console doesn't load when I click the IRP button). If I provide the correct network path during the installation, the RT renderer works, but then i'm always uninstalling the previous version.

MartinB:
Probably the vray and vray-terminal wrapper scripts are not correct, because they use full paths.
You'll have to modify them to use some kind of `pwd` scripts trickery.

Cheers Teodor,

RT is all working again now i've edited the vray and vray-terminal wrapper. Strangely it doesn't lauch the vray-standalone console like it used to, but RT still works...

Can you post the log from Maya? (you have to start Maya from a terminal)

This is with a clean maya scene, create a sphere and a vray rect light and click IPR button. And the vray frame buffer is updating as expected when I move the sphere around or change attributes.

I just remember a separate 'v-ray standalone' window launching when I used RT previously. I don't think it matters as it just used to scroll the below information into that window instead of my Linux console.

Hm, what happens if you run ./vrayterminal "sleep 100000" ?

[MartinB]

The VRay Standalone console launches with the above command, but I have to run it from /vray/bin/ directory. I think an environment var might be wrong our side, or I didn't edit all the wrappers properly. Its pointed me in the right direction at least
