ok, i hope the screenshot attaches without a problem =/

after fighting with vue for 2 days.... i'm about to rip my hair out.  i read the thread on how to get the transparency to accept an alpha picture.... and this MIGHT be the way i go for what i actually have in mind, but i was trying to find a ..... "simpler" solution.

i'm trying to make a box, or sphere, or cone, or ANYTHING be solid, but with cracks.  if i put a point light inside, theoretically, it will shine through the cracks, right?

nothing i did worked yesterday.  the alpha map worked this morning.... kinda.  i still ended up with the rest of the material being partially transparent for some unknown reason.

so, i decided to look at functions.  i found the one for "sparse cracks" and used it, tweaked it some...  and i LIKE the effect....

however, its NOT what i want - i want the parts that are currently transparent to be solid, and vice versa.

HOW do i invert/reverse this function so the white is black and the black is white so the transparency is then correct?  (and if it happens to only be a feature of pro on up, i'll be very VERY tempted to strangle hubby for making me pass up the sale at e-on on sidegrades.  no, i wont actually strangle him)

Rarer than a hairy egg and madder than a box of frogs....
