how to see the displacement in the viewport

quimeramistad

hello, everyone, I'm just trying to see the displacement maps in the viewport pane , but I don"t know where or what to do . I tried the subd thing, the mesh smooth things and others , but none of what i tried worked . Someone can help?

You need to go to the Shader Mixer and create a new shader for the figure using the displacement map as a diffuse map. That will change the figure's skin to the displacement map.

Unless you meant you want to see the actual displacement, in which case that's not possible. Render time only.

yes, i work only with the viewport (render is too long ....old cp ) so I wanna work with everything on viewport and screenshoot it . But when i apply the displacements, nothing viewable in viewport.

Displacement is an Iray feature.

Unfortunately the Draw stle beats a render because it cuts corners (though it usually still has more noise than would be acceptable on most renders). If you could turn on all the extra features it would take as long as a render anyway.

Displacement is also in 3Delight which handles it different and better than Iray.

Displacement does not show in the Texture Shaded viewport.  I often see people write that displacement does not show in the Iray preview and that is simply not true.  Did yhou try adjusting the Displacement SubD?  It's a setting that will appear in the surfaces pane when displacement is active.  It goes as far as 12, but it really doesn't seem to do anything above 6.  A displacement map with any detail will not appear to do anything at all until you turn this setting up at least a few notches.  Displacement, as well as bump and normal, are also dependent on overall figure or object SubD, although unless it's extremely low poly this doesn't make a huge difference.  Mesh Smoothing will not help here.

While that's true, the point is that the displacement map is passed to whatever render engine you're using at render time. It's not available in the OpenGL viewport.

Not true! And it does not support microdisplacement, 3Delight is capable of producing nice detailed displacement even on one poly planes. at base resolution.
