View Full Version : dirty edge shader?

first up i'm a complete nodal noob - and i'm trying to create a dirt/rust surface - first question would be is there anything in all the materials and shaders that will do this for me?


if not then i'm figuring that i need some way to tie that dirt to local edge density/ angles (no clue how you'd do this)/ and distance - that to me seems complex as hell and likely well beyond my abilities so going to need some help :) - anyone know what needs done?

edit:
should probably point out i'm using lw 2015.1

Does the link on the LW 3rd party plugins website no longer work?

Check the manual for using procedural textures. If you do this nod ally its best to use the layers nodes. Once you get the colours right, copy and paste the same texture to a bump map layers node. Experiment using procedurals as alpha maps also.

Definitely worth persevering with occlusion settings.

yeah that site just likes the the authors site which doesn't exist anymore :( - note to newtek - dirt/rush shader or whatever its called - will try reading through that thread tomorrow see if there is something in there that can help me - anyway this is what i've got so far with the occulsion "dirt" :)

I have Substance Painter, but I'm going to have to give Quixel a whirl :)

Occlusion dirt looks pretty good so far...nice and subtle.

if you want something like PhotoShop, try PhotoLine ($80) http://www.pl64.com

$150 for Substance Painter ain't that bad though...

bought 3DCoat over here  ($380)
-one of the best sculpt apps
-one of the best UV generators
-one of the best 3D paint apps
-one of the best retopo apps

Nice model! One technique you might find useful is using distance to control Nulls to add texture to specific spots. I've attached a sample object / scene. The basic technique is to add a control Null (mine is named TextureNull_HeadonDamage), which is then used in an Alpha-blended Gradient layer to apply a Color and Bump Turbulence texture to the leading edge of the hull. I started with the rust Color, adjusting it with the Scale and Z position of the Turbulence and the "effective distance" in the Gradient slider. When it was tuned to my satisfaction, I copied the two layers (Additive Turbulence and Alpha Gradient) to the Bump channel. Be sure to enable VPR to see the effect.

Note that the control Null(s) need to be parented to the Hull so that when the Hull is rotated / moved, the texture doesn't flow / change. You can add as many control Nulls as you need to influence various parts of the model. Note also that the Turbulence texture is blending mode Additive to add it to the underlying surface components.

Looks pretty good, care to elaborate on the set up?

Photoline is a very powerful application and reasonably priced. And I agree with you on 3dCoat. The Education Version $99 may be a good way to get started if finances are an issue for our friend. It can create the worn-edge look very easily with it's PBR shaders, similar to Substance Painter and Quixel Suite:

yeah, i've been asking myself if i should get DDo or Substance, only to come to the conclusion "no"

learning yet another app is just too tiring, especially considering i read both DDo or Substance had troubles here and there.

(bugs / workflows)

if doing tons of "worn metal" texturing, i'm sure i'd think twice about it.


but i'm going with 3DCoat, which gets better by each version anyway   http://erikalstad.com/backup/misc.php_files/smile.gif

Also look up Digital Carvers Guild Anything Goos, similar to grit node but with all more options.

Had never heard of this - looks great, thanks for posting!

Slightly OT: The proliferation of paint apps on this thread is interesting. I use Zbrush but am thinking of investing in 3dcoat as it has Photoshop style layers and it seems there's no need to ramp up an object's subdivisions to millions of polys before you can paint on it. Especially good for hard surface models. Can other 3dcoatusers confirm this difference between the two apps?

That is correct. 3dCoat has more of a Photoshop paradigm with layers. Even the shortcuts are similar. "X" switches the color chip, etc... And yes, you can paint on low or high resolution meshes. The exception is when you paint on a "Volumetric" object, then it more closely resembles the polypainting in ZB being that it's resolution dependent. But for your standard everyday surface-based mesh, it works like a charm. 3dCoat's painting, texturing, UV'ing are simply a pleasure to use. :)
