Procedural camo texture - reworked

The old texture was not customizable enough, so I quickly put together a new one:

color defines the base of the camo model

tint 1-3 modify the existing (one tint per patch layer)

scale, detail, distortion and vector control the overall form of the camo texture as in every other standard texture

Since the result is a texture (and not a shader as usual), I should explain the outputs as well:

color is the default output that you would expect from any kind of texture

height on the other hand is pretty useful for advanced shading, because it is composed of each patch layer. This creates a normalized 4-stepped heightmap (1 base color + 3 tints)

In this image, you can see the result of the height as the bumpmap input combined with color and reflection.

Wax Shader

This shader is basically just a tweaked Subsurface-Scattering Shader:

size has to change based on the model (sets how far light can travel into the model)

radius changes the same as above (in boundary with max=size), but changes the range for the RGB values

New Material-Base object

Added many small features like:

different angles

different forms

cylinder

cone

inner sphere (as contrast to transparent materials)

small height differences

depth-giving floor-texture

2 lights from behind (blue & red) (giving the object more form)

HDRI - Illumintation

Glasses

It has been some time since I last uploaded some images here, so time to catch up!

This was a test with different ior-values for the glass and metal.

I’m not yet at a point where I know which values to use for what material, but I’m working on it. :)

I used a wood-material for the floor from some time ago, but I think it still looks neat in this composition!

100% procedural concrete shader - 2nd attempt ^^

I was able to set it up in a way, that you can control the amount of rough and smooth concrete.

Update for one of my old interior renders =)

Painted Wall - Procedural Texture

Just wanted to share my progress on the marble tiles!

I also added a little Icosphere to illuminate the tiles and emphasize the reflections.

Marble material - procedural textures only!

As I was trying to create this marble material, I browsed the web for inspiration, why my result didn’t look as good as the original photo.

The difference was caused by these small little flat faces on the marble surface, which are facing different angles.

That said, I used a voronoi cell texture and took the color values as normal map input.

With a few tricks, all issues were fixed that the normal map caused (you know those black bumps?). 

Camouflage material - procedural textures only!

Using texture setups in the following pattern:

n = number of colors | Texture Setup = Mapping node + noise texture + less than (math node - value: ~0.5) + color mix node (factor input = less than output)

Number of texture setups = n - 1

Then just select the colors you want:

The first color mix node gets 2 new colors. The rest gets the previous color + 1 new color.

Semi-procedural fishbone-wood planks!

I used multiple textures with my procedural wood texture. All textures made in Krita. The Textures used:

Height map - Only the edges of the planks are black. The rest => gray.

Alpha maps - One for all horizontal planks and one for all vertical planks (When viewed top down). I found that 1 Map for both is enough.

Color variance map - greyscale values for all planks. Edges black again. Direct neighbors have never the same value.

Then combine them all and use 2 Mapping nodes for the rotation. I used the alpha map as factor input for a color mix node with the 2 color inputs being the vector outputs of the mapping nodes. Plug the result in the wood texture node and voila, you now have the desired pattern! 

The best thing being that you can change your texture node how you like, because the only thing making the pattern work, is the vector input that we just made! :)

When you are done simply make a color ramp with the colors you want the wood to have and add a color mix node “darken”. I highly recommend that you use “darken”, because it guarantees you that the colors from the color ramp will not get any brighter which might be important for realism. Then change the factor value to your liking.

Also don’t forget 2 important things for the material!

Use the height map and the displacement of the wood grain with 2 separate bump map nodes, so you can keep adjusting different things independently.

Always use Fresnel, when aiming for realistic results! Just combine your shader setup with a glossy shader via a shader mix node. Then use Fresnel as the factor value for the shader mix node.

I made a door! o3o

Only procedural textures used!

Updated old Sculpt of me - new material (wax)

Old mesh: ca. 2.1 million faces

Retopologized mesh: 0,65 million faces

Procedural Mud Shader!

Here is quick look at a new shader I was working on!

I think it’s pretty neat.. but the render times get awfully long for things like that, because I can’t bake it if it ain’t finished.. ¯\_(ツ)_/¯

And we are talking here about texture scales * 64 to get a good resolution.

Basically it’s like that:

make a texture

make a copy

take the double scale for the copied texture and combine them

repeat until it looks nice

And because I usually have to start at scale 8 for it to look good, scale 8 is my scale 1. This quickly escalates..

8*2 = 16 | 16*2 = 32 | 32*2 = 64

Quick Update on the Procedural Wood Planks!

I am not quite satisfied with the details but it’s still a huge step forward! :)
