Worn Edges Example

[Despot]

This was done for Steve Talkowski really... using the same principle seen in the teapot render, namely, applying carefully chosen textures to each Curvature colour value.

It works quite well... apart from there is no way to apply a different roughness value and/or bump to the area boundaries created by curvature

Looks pretty good J...

@ The Dev Team - I like curvatures flexibility but it needs some way of feathering between the zones so maps can merge more realistically rather than the sharp cutoffs at present.

This is promising! Though, that cutoff is pretty sharp. I'd need more of an explanation on how to set this up. Quick tutorial video anyone?

I'll record a video tomorrow Steve...

Ooh, sorry Slater - daddy forgot, it's your feeding time again... and maybe after, if you're good, you can go and play with the other little trolls

Just happened to see this post again. See attached material graph for how to use curvature with multiple texture maps and increasing control of the transition between the areas.

I use a color key mask to select red/blue from the curvature, but if you do not wish to distinguish between positive and negative curvature you can just set positive/negative to black and use directly as input to Color Composite/Source alpha.

I have noted that we may wish to add some increased control of falloff/blending directly to the curvature procedural.

Brilliant Soren, thank you - would you be able to attach the actual .kmp file, rather than building from scratch ?

Here you go - a version just with procedurals (ugly as ...., but you get the idea). When tweaking parameters for this thing, it can quite useful to use the node preview functionality (select a node and hit C for color, A for alpha and B for bump).

(attachment deleted, see below).

Cheers for that Soren, much appreciated...

Is an ironic answer?..especially "play with the other little trolls? "

[Despot]

Yes, of course it's ironic Slater 

Anyway, your prayers have been answered, there is now a tutorial/file for you to play with, providing of course you have KeyShot 6

Looking super interesting.
Wish I had mat graph for my date material... But, alas...

We recently fixed a bug which caused the mtl-file I uploaded earlier to be slightly incorrect - the Curvature node was duplicated which was not intentional. I have attached an updated mtl.

Additionally, I added another (simpler) one demonstrating how to use curvature with a color gradient node to obtain full flexibility of the colors and falloff behaviour.

It looks like super fun thing to use. Recently I try Substance designer and it's node based procedural workflow is pretty cool... Somehow reminds me on this...
