does anybody know these commands??
and can they be used from inside maya or are they only made for the MR standalone??
Im asking because I really dont get rid of that "out of memory" message..
-swap_dir "directory " 3.2
Specifies a directory for disk swapping. When mental ray runs out of memory, it can push memory objects to disk, and load them back when they are needed again. mental ray does this much more efficiently than the operating system, which has no semantic knowledge of the data. For example, source geometry is not likely to be needed anytime soon, or at all, after it has been tessellated. The directory should be on a local disk, not a file server. This option should be used together with -swap_limit, and given before -swap_limit on the command line.
-swap_limit size 3.2
Specifies the number of megabytes to write to the swap directory specified with -swap_dir. This space effectively becomes an extension of system memory. The default is 0, which turns off swapping. Good numbers are in the low thousands.
