I have rendered from gp2x. It did take forever but I did it.

Same here, I did it with my first hexawe release.

the best thing to do is to make a windows shortcut with the command line arguments (as herr prof said!!)

on other systems maybe you cannot put command line arguments into a shortcut but you can make a batch file with just one line in it and it will work much the same

Ok, finally got it thru my thick skull.  Rendering channels separately is awesome.

You can do it:
...
2. Do it on demand by running it via the command line with the render arguments. Handy if you want to only render quickly once
...

For that, if I want to render each channel separately and "offline" it would be:

lgpt -RENDER=FILESPLIT

in the command line and then the rendered files will show up in the project folder?

You can also do this to set different versions for any config.xml argument. So for example, one shortcut to point to a project folder on a dropbox directory and another that points to the local directory. Dropbox is handy if you like to collab with other piggers.

thanks guys
