You would need to do this manually trough scripting. (I'd actually need to check if Unity currently supports GetPixel()ing on a movietexture). assuming it does for a second, you could read color values for your pixels, and use those to change coordinates of vertices in your plane mesh.

Depending on what you're trying to achieve there might be a more effecient way than using a movie texture. Hard to tell though, as your question is rather slim on details :)

thanks, The animation window does not have a curve for displacement. I want to have a terrain change over time, and the terrain editor has no ability to keyframe displacement. I thought a movietexture would offer the option of time based displacement, though no way to use a movie as displacement. jcb
