image editor contrast curve: scope of impact

Support Materials and Textures
1

Hi. I’m using a grayscale heightmap image to displace a landscape.
I’m trying to morph my landscape by modifying the image editors contrast curve. I’d like to see the displacement respond in real time but it doesn’t. Any ideas? Saving (and reloading) seems to be the only way to update the texture.
thanks

Load the map as a texture, and apply it with Displace Modifier. Vary Strength setting to see the deformation real time in Object mode.

Thanks ridix, but that is what I am already doing. I was actually trying to find out why the curve control only affects the view of the image rather than the image itself. I was trying to ‘gamma’ my landscape height.:slight_smile:
