Painted Marble, Stone, and Wood shaders...

in The Commons
I've been playing a lot of Assassin's Creed: Odyssey, and it's immersive world had me wondering...are there any shaders that look like painted marble, stone, or wood shaders?
Comments
There are. do a store search for "shader marble", "shader wood", etc. for examples, although you'll have to weed out the non-shaders from your searches. For stone as well as "shader stone", try things like "shader masonry", etc.
The ones I've come across are more natural marble, stone, and wood shaders. I was looking for some that had a painted look. I know I can just pop in a marble shader, remove the diffuse map, change the color, and just rely on the normal and bump maps for texturing. I was hoping for more shaders with peeled effects (where you can see bits of the wood and marble under worn paint).
EDIT: Rusting Painted Metal Iray Shader Wet is a great example, but it's a metal shader.
There are these that i know of might be worth a look

You could always use a marble shader and then a geoshell with a paint shader and an opacity mask to show what's underneath.
I know you are looking for a pre-made shader and this isn't what you asked for, but Filter Forge has several filters which could produce a PNG alpha layer of a paint layer to use on whatever base layer you'd like...
Here are some examples of what you can make...
These are all made with Filter Forge and are seamless, so if you open up the thumbnail you can download it at full 2048 x 2048 resolution.
The second and the last are peeling paint over a marble, the rest are over old wood.
Plant, thank you for the suggestions! I looked them over and it's pretty close to what I've had in mind.
Uthgard, if I can't find shaders, then I will definately use a geoshell. Maybe even a displacer...though, I'll have to fiddle around with that 'cos I don't use displacers that much.
McGyver, those are pretty freakin' amazing! I've heard of filter forge, but I didn't know what it did. Thank you for taking the time to make those and show me what the program can actually do. It's really a step in the right direction; AND it let's me make what I want, rather than relying on someone else's vision.
Thanks, I'm glad you like them... To be clear, just so you understand how those were made...
For example, I'll pick the second from the top...
First I chose a filter that produced something that looked like a painted surface... in this case "Baked Paint" https://www.filterforge.com/filters/5096.html
Then I fiddled with the filter's controls a bit and rendered it out as a Jpeg to 2048 x 2048... (BTW- whenever you want a seamless texture be sure to tick the "seamless" box, in the controls section, as not all filter creators who specifically make a seamless filter remember to enable that before they publish it)...
Next I opened the filter "Peeling Paint" https://www.filterforge.com/filters/295.html and messed around with the variation and size a bit until it looked sufficiently close to what I wanted and then I opened up the "Baked Paint" image I just made in Filter Forge...
Some filters are designed to generate a texture or pattern as an image (Texture Filters), but others are designed to take an rendered image and generate a version of it with an effect added to it (Effects Filters).
In this case "Peeling Paint" takes the input image and make the input image look as though it has cracks and missing chunks...
I played about with the controls a bit... altered the damage/chips/peeling amount, as well as scale and turned off the background (this filter allows you to shut off the background so you can render the final image as an alpha layer with missing sections) and rendered out a PNG alpha layer version of the Baked Paint image, that now looked battered, cracked and peeling...
Next I chose a simple marble filter, "Marble Maker" https://www.filterforge.com/filters/15667.html.
I fiddled a bit with that too, but basically not much and I rendered out a 2048 x 2048 Jpeg image of those results...
Finally, I opened the marble image in Photoshop (any image editor will do) and then imported the Peeling Paint layer on top, made sure it was all lined up and then flattened the image into a single layer and saved it as a Jpeg.
I didn't bother to make normal maps or bump maps in this case because it wasn't necessary (both of the "paint" filters involved can generate bump and normal maps, but not all filters do and not all do a great job), but to achieve a proper effect where you have one type of texture on top of a different one, it would involve a few extra steps... and it's not necessary to describe that at the moment.
This is all actually pretty easy and once you get used to it, pretty quick and usually well worth whatever effort involved.
Please note I have the Professional license, there is a difference between that and basic, so be sure you chose which one is right for your needs... I recommend downloading the free 30 day trial version https://www.filterforge.com/download/ before you buy so you aren't surprised or disappointed if it's not your thing.
I only mentioned all this because in the past, some people in Filter Forge related discussions have seemed to misunderstood what Filter Forge is, and what it's for and as a result have been disappointed that didn't do what they thought it did.
Anyway, good luck and I hope this was helpful and not overly long.
How does Filter Forge compare to Substance Painter besides being cheaper? The one thing that has be kind of leaning towards Substance Painter is being able to texture the models in 3D. Seems like Filter Forge & Substance Painter would at least complement each other well.
Filter Forge is a node-based image modifier, which can be used to make textures. It doesn't ahve any kind of 3D painting as far as I ama ware, or the ability to take data (such as occlusion) from a 3D model. It's closer to Substance Designer, if anything.
As Richard said, Filter Forge has no 3D painting ability... it's strictly used to create 2D images (mostly, or preferably, seamless images)... it can be used like the "filter effects" in image editors like Photoshop or to create texture images for use applying to 3D models when either used as the reference image (and/or normal/bump image) in a shader within 3D software like DAZ Studio or a 3D painting program like Substance Painter, where you can create shaders using 2D images (which is the where the part about the images being "seamless" (or tiling) makes most sense)... Or the textures can be applied to a UV map in an image editor manually, in which case you don't necessarily need a seamless image.
Basically, the images I posted above are exactly what Filter Forge makes... they are the end product.... if you take them and enter them into the image window in the Base Color node an appropriate DAZ shader it will work... but I didn't make Normal maps to go along with them and without bump or normal maps, obviously they'll look kinda flat.
I forgot to mention earlier that if one would like to make normal maps for seamless textures they make or find, there is a free program called "Materialize"...
https://boundingboxsoftware.com/materialize/
It's fairly easy to use... It takes a little trial and error to get good results... but it's free, so you can't argue with that.
There is also "Awesome Bump"... https://github.com/kmkolasinski/AwesomeBump ... it's free also...
Both programs can generate multiple types of maps like Ambient Occlusion, Metallic, Bump, Height Maps, Roughness and Normal Maps...
Honestly, depending on what effect you are trying to achieve or settle for, sometimes stand-alone programs like these are just easier and quicker than generating different parts separately from FF and fiddling with it in an image editor, with these programs you just load the final diffuse image and tweak the controls until the final material effects maps look right, or close enough and then render them.
https://www.daz3d.com/architectural-iray-shaders has one that is peeling paint over wood siding.
also check out the various "layered" shadres in the shop. The ones I have are all 3DL not iray so nothing specific for you that I can point at though.
