Hello all,

I have a global var called LOD ($LOD). In my pre-render script i tried

set LOD = 1 (also tried -g)

and

setenv LOD = 1

Sometimes this works, but most of the times it does not. If I make a simple copy sop and set the number of copies to 10*$LOD, typing above statements in a texport wont change the number of copies, until I force a re-cook of the node. Unfortunately, running it in the pre-render script does not always pick it up either.

Is there a better / more reliable way to do this?

Cheers,
Koen

An alternate way is to use a ch() reference to a LOD channel, and use Takes to switch between LODs, perhaps?

Takes seem well suited for this task. Thanks for the hint. I really liked the global var work flow though, because I could set my working LOD at any time from the global vars dialog.

With environment variables, you might have to run the “varchange” command.

That did it,
thanks mark!
