View Full Version : Manage displacement

02 February 2005, 10:35 PM
Hi !

I'm wondering for long time now how do you manage your displaments in Maya. How you manage its size? I mean, how to tell maya (through a shader) white values of my map is 3 units and black ones are -1 for instance? (And what is useful in shapes displacement attribute tab?)

(sorry I didn't find any tutorial or decent info in the doc)

Thx thumbs up :thumbsup:

Total Black (rgba 0/0/0/0) is always zero displacement and total white (rgba 1/1/1/1) is always full displacement. One unit of displacement (total black to total white) seems to be 1cm. You may scale the displacement by scaling the alpha value of your texture, since the displacement node uses it's alpha channel as input.

For instance: You want white values to be 3 units high and black values (-1) units deep, so you set the alpha gain to 4 and the alpha offset to (-1).

Cant tell much on the 'Displacement Map' tab, I usually use mentalray's displacement approximation.

Ho thanks... It was just it. If I knew :D (I though it was required to had particular nodes to outputs certain values...)
