Re: [PyMOL] transparency of cgo plane

[Robin O. <rob...@ps...>]

Thanks for the suggestion, it led me to the root of my problem. I 
discovered this morning that my problem was more to do with my 
understanding of cgo syntax/hierarchy/ordering. Hence
   
    obj.extend([COLOR, 0.8, 0.8, 0.8])  # greyish
    obj.extend([ALPHA, 0.5])
    obj.extend([BEGIN, TRIANGLE_STRIP])

and variations on it, doesn't work. But the below does.

    obj.extend([ALPHA, 0.5])
    obj.extend([COLOR, 0.8, 0.8, 0.8]) # greyish
    obj.extend([BEGIN, TRIANGLE_STRIP])

Cheers,
Robin
