Using the mental ray flags with the -file option

When rendering render layers, one may use the command
Render -r file filename.mb
However if your render contains mental ray, you can add the usual mental ray flags like so

 -mr:v/mr:verbose int   Set the verbosity level.
  0 to turn off messages
  1 for fatal errors only
  2 for all errors
  3 for warnings
  4 for informational messages
  5 for progress messages
  6 for detailed debugging messages
 -mr:rt/mr:renderThreads int   Specify the number of rendering threads.
 -mr:art/mr:autoRenderThreads  Automatically determine the number of rendering threads.
 -mr:mem/mr:memory int Set the memory limit (in MB).
 -mr:aml/mr:autoMemoryLimit    Compute the memory limit automatically.
 -mr:ts/mr:taskSize int Set the pixel width/height of the render tiles.
 -mr:at/mr:autoTiling   Automatically determine optimal tile size.
 -mr:rnm boolean    Network rendering option. If true, mental ray renders

As an example using one of the above flags we can get verbose messeging.
Render -r file -mr:v 5 filename.mb

What is your mental ray vr?

This is a little off topic, but has anyone else been having license issues when rendering MR (batch) with render layers? It seems that at every layer stop/start, there is a license check-in and check-out. This will often cause one host, to have multiple licenses checked out. Once the job is finished, all the licenses are checked back in.

Anyone else had this problem?
