Hi all. I have a few walls and corridors that I would like to run textures along the corner edges - some knocks and scratches, that sort of thing. I've got my gradient but not sure what to plug into the input channel!

Is there a node that can detect the angles of my corners so I can control fall-off etc or is it a weight-map job?

Thanks, Mark

oclussion is a diffuse shader node that will darken corners, you can plug in other textures into the spread and see if that is close to what you want.

There is the great Edge node in the Denis Pontonnier's node collection - http://dpont.pagesperso-orange.fr/plugins/nodes/Additionnal_Nodes_2.html
It should do exactly what you're after, much faster than any ambient occlusion based shaders would do, too.

Many thanks for the pointers. There's that use of the DP Kit again - that Denis fella deserves a medal or something! LW would be pretty much dead to me without it!!
