headus 3D tools

I'm writing a plugin at the moment and having to use perl, the problem is that I have to use the system command to run UVLayout and the 3D application loses focus until the command has completed. So as soon as UVLayout closes and passes focus back to the app, the .out file has already been deleted.

Would it be possible to modify UVL to allow a parameter passed in to instuct UVL to not delete the .out file ?

What do you think ?

Cheers

James.

Normally you'd want to leave UVLayout running all the time, instead of restarting and exiting again each time you send an object over. The "out" file is being deleted because UVLayout cleans up after itself whenever it exits.

What I recommend is reading up on how to start a background process in Perl, and run UVLayout that way. I've never used perl, but some googling came up with ...

system( "command &")

... but I'm not sure if that a Unix thing only and wont work under Windows.

Maybe the "open" command is a better way? It'll start the command and return control back to the script.

Thanks for the reply Phil. I've decided to move over to python after realising that perl is proving too difficult to run uvlayout in a background process.

I've run a quick test in python and it seems the functionality I need is there.

I'll post my results in the next few days.

Cheers.
