Still appears to be an issue with setting lux_subdivision to 1 or more on Poser 6 and 7. Poser 6 error output:

Partial Poser 7 error output:

For the most part, the error is pretty much the same only with it being a bit easier to track down in Poser 7. Again, CC subdivision works on both versions. Also made sure to have the backslash escaped this time as to make it easier to read.

Hope that helps.
