Refining the displacement effect

- Although we have so far in our displacement…exercise managed to create a render time…displacement effect, we will, in most instances,…want to exercise finer control…over the displacement than we are currently getting.…So in this video we're going to demonstrate…how we can go about using some…Mental Ray specific controls to tweak…and refine the displacement that we are seeing.…Specifically, we want to add a Mental Ray…displacement tessellation approximation node…to our egg geometry, which is a complicated…sounding name for what is in reality…a fairly straightforward process that will add…render time subdivision, or tessellation,…to our geometry.…

With our egg selected then, let's come to…the menu system and choose Window,…Rendering Editors, Mental Ray,…and from there open up…the approximation editor window.…What we want to do inside here, again making…certain that our egg geometry is indeed selected,…is click to create a displacement…tessellation approximation surface.…Now whilst we could over in the attribute…
