How to access bucket min/max-subdivs through maxscript

[chroma]

Can't find anything about how to change the bucket image sampler's min and max subdivs with maxscript for vray next. How can I access these settings?
It's not in the list of showproperties vr

It's the two level sampler type:

vr = renderers.current

    vr.imageSampler_type = 1
    vr.twoLevel_threshold = 0.1


    vr.twoLevel_baseSubdivs = 1
    vr.twoLevel_fineSubdivs = 8
    vr.twoLevel_threshold = 0.1

Oh, la la. Thank you!
