i have a plane, i want to displace it with a bitmap so it looks like a hole is in the middle of the plane. The reason am asking is because the 3dsmax "displace" command allows to displace geometry with bitmaps and interactively view and control the amount and the look of the displacement whereas in maya i have to render to see the results of my displacement. I want to make a crater on the road like a meteor crash, so i want the hole to look somewhat organic and natural, so i won't mind an alternative workflow.
