Pointiness Output


Woooo! I have to say I’ve been waiting for this for years!

It’s basically the same as dirty vertex colors, but on the final geometry (after modifiers) and without all the hassle of adding it to every single mesh.

The commit from Sergey [227a9407]:

Cycles: implement pointiness geometry attribute

This attribute means how “pointy” the geometry surface is, which allows to do
effects like dirt maps and wear-off effects on render geometry. This means the
attribute is calculated for the final mesh which means no baking (which implies
UV unwrap) is needed. Apart from this the behavior is quite close to how vertex
dirty colors works.

The new attribute is available as an output socket of Geometry node.

There’s no penalty for the render time, only some delay on scene preparation
(the delay is linear of the mesh complexity).

  • This is awesome
    waited so long for this.
    But (bassic question) how to i get it into my Blender Version? I download the raw .diff and…?

    • You can get a recent build from builder.blender.org/download, or build it yourself from the source code.

  • simply awesome, now on to the AO… just kidding, this will be incredibly useful.
