    Luma key on white in the mask (global) module

    by Jaime / www.starloops.net » Wed Jan 10, 2007 11:49 am

    Hello, there is 5 inks option in the module:
    Normal,Dark Luma, exclusion, test and test 2.
    But no White luma?
    We would like to have a White luma avaible to create a mask to have black between multiple screen parts.

    I saw in the script:
    elif param['selection'] == 'DARK LUMA' :
    modul8.setValue ('direct_globalMask_surfaceBlend_Src','SRC_ALPHA',0)
    modul8.setValue ('direct_globalMask_surfaceBlend_Dest','DST_COLOR',0)

    Could you tell me how to Invert the Luma to make in this mask the white transparent ?

    Best

    You can try to modify the module yourself, with differents combinaison of blending.
    Test, test2 is here for that ...

    Or more simple : make a picture with transparency ! (like psd or png)

    after playing around a bit I was able to make this work as a White Luma Key:

    elif param['selection'] == 'WHITE LUMA' :
    modul8.setValue ('direct_globalMask_surfaceBlend_Src','DST_COLOR',0)
    modul8.setValue ('direct_globalMask_surfaceBlend_Dest','INV_SRC_ALPHA',0)

    and then just make sure and add in WHITE LUMA to the "Init With:" string.
