Multiply with the mask. Where the mask is white, the displacement will remain. Where the mask is black the displacement will be nullified.
Consider:
White is 1, black is 0.
Any value, x, remains x when you do x * white. Any value, x, is 0 when you do x * black.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
