Set Default To Clampmask Off?

[user_deleted]

Is there a way to set the default mask behavior to not clamp? I have some shake 2 scripts that I want to render in shake 4, but the new feature (clampMask) is set to on by default. I'd like this off by default. I have tried playing with a startup.h file, for example:

nuiPushControlGroup("NRiMask.Mask");
nuiGroupControl("NRiMask.maskChannel");
nuiGroupControl("NRiMask.maskPercent");
nuiGroupControl("NRiMask.invertMask");
nuiGroupControl("NRiMask.clampMask");
nuiGroupControl("NRiMask.enableMask");
nuiPopControlGroup();

nuxDefExprToggle("clampMask", 0);

but did not get any results. I have thought about writing a perl script to change the files, pre-render, if there was no way of overriding this default.

BTW: are there any other pitfalls I might encounter when rendering shake 2.x files in shake 4?

Thanks,
