Tutorial: Displacement Subdivision

This is tutorial shared by Eugenio "Jenny" Sorokovoy.

This image show displacement flaw.

The reason for this flaw. The image shows the view on the geometry that makes the problematic surface. You can see the small alterations on the surface that cause the uneven subdivision.

I've used "subdivide and smooth" plugin to show how the method of vray's subdivision work. You can notice that the tight subdivisions are the ones that seen in render as "artifacts"

How to correct this? Here I've closed up the small chunks and increased the size of the right side of the "L" shape surface. also I've applied the SS plugin just to show you guys how this affect the subdivision. NOTE: the SS plugin and the Sketchup lines for subdivision are not necessary for this to work properly- it's just a tool that helps me to see subdivision that will accrue in render of vray.

Now after rendering you can see that the evenly divided triangles are also shown equally in the render.
