  • plan: add material to donut & icing + color it + give it the right reflection flavour?!

  • select icing

    • add new material

    • make it e.g. pink "Base Color"

    • snd prop "Roughness" (how reflective the material looks OR or sharp the reflection looks)

      • 0 => mirro | 1 => alost no reflection
      • vs "Specular" prop (maybe don't touch this yet bec every object has reflection, but in different strength)

    • "subsurface scattering" prop => light tends to go a little entering into (most) material

      • "Subsurface" prop it is called
        • set to 0.3
        • "Subsurface Color" e.g. set to pink
        • "Subsurface Radius" => how much the light bounces into around
          • setting it to e.g 0.3/0.1/0.1

  • donut

    • add new material
    • "Base Color" orange'ish
    • subsurface 0.1
      • "subsurface radius" 0.1/0.1/0.1

  • camera

    • place camera

  • splitting the view

    • right click on a border and choose "vertical split" or "horizontally split"
    • moving light

  • light

    • e.g. Point / 330W / Size 0.45 m
    • light from left

  • render settings (light trick)

    • "Color Management" => "View TRansform" => set to => "False Color"
      • tells you if smth is overly bright

  • change plane color to rosa

  • remove noise (using denoiser)

    • go to "view layer" panel turning on => "Passes" => "Data" => "Denoising Data"
    • do another render
    • go to "Compositor" tab (top tabs)
      • SHIFT+A => add "Denoiser" node (search)
      • connect
        • "Noisy Image" (Render Layers) => "Image" (Denoiser)
        • "Denoising Normal" (Render Layers) => "Normal" (Denoiser)
        • "Denoising Albedo" (Render Layers) => "Albedo" (Denoiser)
        • "Image" (Denoiser) => "Image" (Composite)
      • go to "Image Editor" => set to => Render Result
      • reconnect - "Image" (Denoiser) => "Image" (Composite)

plan: randomize sprinkle colors, increase sprinkle variety, add (candy) spheres
source: Part 2, Level 2: Random Materials - Blender Beginner Tutorial


  • shading sprinkles
    • on the top bar click tab "shading"
    • "shading mode" just like screen layers ???
    • lower part is the "node viewer"
    • make sure you have the one sprinkle selected
      • add a material to see a node in the shader window
    • "base color" in node
    • add new node via SHIFT+A & choose "input > object info"
    • connect "object info - random" to "base color" (main node???)
    • add new node via SHIFT+A & choose "converter > ColorRamp"
      • drop it into the connection from "object info - color" => "base color"
      • (colorRamp) add more colors by clicking "+"
      • (colorRamp) make colors binary by changing gradient type from "Linear" to "Constant"
    • set roughness high

  • add variety of sprinkles
    • create sprinkle group
    • copy original sprinkle like some times
      • creating long, middel, small, and all that also rounded, so about 3 to 6 sprinkles
    • select icing and switch "Render > Render As" to "collections"
    • select "Collections > Instance Collections" the "sprinkles" collection
    • change origin points of the sprinkles to "Origin to Geometry"
    • you can change the seed "particles > emission > seed"

  • add spheres
    • add a uv sphere SHIFT+A
      • 16/8
      • 4mm
    • shad smooth
    • single color (new material) low roughness (shiny)

      • select icing
      • enable "collection > instance collection > use count"
      • 30/30/60/30/60/1 (where 60 is medium stuff and 1 or 2 the sphere)

  • optinal varaible stuff
    • maybe scale .2
    • number 1500

plan: Texture Painting the donut
source: Part 3, Level 2: Texture Painting - Blender Beginner Tutorial


  • Texture Painting first step
    • switch top tab to "Texture Paint"
    • we skipp UV unwrapping (bec. when we added the torus blender already uv unwrapped it) (top tab "UV Editor" => shows the UV's map)

  • setup - Texture Painting - UV unwrap - change size UV map squares
    • switch top tab to "Texture Paint"
    • left window click "New" (on the top)
      • creates a new image
      • set it to 2048*1024
      • give image a name, e.g. "donut_texture_paint"
    • link donut and texture
      • go to top tab "Shading"
      • add image node (SHIFT+A => "Texture" => "Image Texture")
        • connect "color" => "base color"
        • on the node select image texture (image symbol dropdown)
    • save image accordingly (maybe re-setup directory structure, put blend file and assets in sub dir)
      • click on left window on "Image" > save (as)
      • ALT+S should be quick save

  • add base color (7:00)
    • we can set two brush colors
      • we can switch these with pressing X (left window)
    • there is an opttion "stroke" > "smooth stroke" (meaybe disable it)
    • paint the hole map in one colore
      • there should also be a "fill" tool, try out

  • paint donut middle part white
    • set second paint color to white
    • set low strength (.2/.3 or so) / radius try 140px
    • we can paint on the model and the map

  • paint donut middle part white - add texture mask to brush
    • left window go to "texture mask" (the N window)
      • click "New"
    • on the right properties menu (material, particel, etc...) go to "texture properties"
      • dropdown "Brush" => select "Brush Mask (Texture)"
        • change "type" =>to "clouds" (dropdown)
        • you can change size of the cloud (e.g. 0.65) (Clouds > Size)
    • on the left window N menu => "texture mask" => "Mask Mapping" => change to "Random" (new rotation on the brush every time)
    • paint the middle (outer and inner ring) (opaque) white

  • paint donut dark parts
    • set white brush to black
    • set brush "Blend" => to "overlay"
    • paint on the top and bottom of donut, give it lighter and darker higlights

plan: giving the donut a more realistic rougher surface (using procedural displacements)
source: Part 4, Level 2: Procedural Displacement - Blender Beginner Tutorial


  • ...
    • select donut
    • go to tab "shading"
    • ensure "look dev"(look development) view mode (where you choose e.g. solid, rendered ...)
      • note: uses eevee renderer to preview material; with an HDRi (???)
        • note: as I understand HDRi: images of environments which capture light source related stuff (as well as color stuff etc) but its basically for light shading ?!

  • add procedural texture (same mode as before)
    • add new nodeSHIFT+A => "Texture" => "Noise Texture"
    • to check look of noise texture we can use an add-on
      • enable add-on => "open Menu "Edit" > "Preferences" > "Add-ons" > search for "node" OR "Node Wrangler"
      • enable "Node Wrangler"
    • now we can CRTL+SHIFT+left-click on the new node ("Noise Texture")
      • this will connect the node directly via a preview to the "Material Output" node
        • multiple CRTL+SHIFT+left-click to change channels (Fac / Color)
      • `command+Z to reverse the effect
      • OR CRTL+SHIFT+left-click on main "Principled BSDF" shader node to reverse the effect
    • we want to use the "Fac" (factor) input channel
      • to drive bumpiness and color
      • common way to add free detail
    • add "Texture Coordinate" node
      • connect: (Texture Cooridnate - Object>) => ("Noise Texture" - >Vector)
      • seems "most" appropriated for like procedural textures
    • set ("Noise Texture" - o:scale) to 1500 (or play around with it)
    • info: real bump and fake bump
    • add new nodeSHIFT+A => "Vector" => "Vector Displacement"
    • connect: (Noise Texture - 'Fac>') => ("Vector Displacement" - '>Height')
    • connect: ("Vector Displacement" - 'Displacement') => ("Material Output" - '>Displacement')
    • CRTL+SHIFT+left-click on main "Principled BSDF" shader node
    • we can check in render view mode ?!

  • note: until this point it is "fake bump"
    • it's not changing the edged of the object
    • you could also put the displacement into the '>normal' input of the main "Principled BSDF" shader node
    • also this displacement we are currently working on expects cycles render engine, you won't see certain options in eevee

  • enable/use displacement in material properties
    • go to "Material" properties
    • g to settings
    • change dropdown "Displacements" from "Bump only" to "Displacement and Bump" (only visible when cycles is used)
    • fixup scale in displacement node
      • set ("Vector Displacement" - o:scale) to 0.003
    • note: the look will depend on the number of vertecies the mesh is having => more => more detail (you can add more with subserv mod)

plan: finishing donut, add larger details, add larger bumps
source: Part 5, Level 2: Final Donut - Blender Beginner Tutorial


  • add larger bumps
    • duplicate (Noise Texture) node
    • set (snd)(Noise Texture" - o:scale) to 200
    • merge/mix both (Noise Texture) nodes
      • add "MixRGB" node SHIFT+A => "Color" > "MixRGB"
      • ensure "Fac>" input to connect to "MixRGB" node
      • we can check again with CRTL+SHIFT+left-click on "MixRGB" to preview the effect only
      • note: ("MixRGB" - o:Fac) set to 0 uses 100% of color1; if set to 1 it uses 100% of bottom color
      • change ("MixRGB") blend type (dropdown) from "Mix" to "Add"
        • note: now it's gonna use the "bright" value from one texture and applies it over the values of the other texture (fac to 1 shold be what we want but still liiks fake, mashed together)
          • the top color is always 100% and the bottom color is affected now by the "scale" option

  • we want clear big bumps
    • add ColorRamp between (snd)(Noise Texture) & ("MixRGB")
    • if we only want to have the white values, we can change the black slider & increase the black color amount, we only get the top values
    • make it 50/50 black/white
    • we can e.g. change by (Displacment - o:scale) to .002 to minimze small values ?!
    • switching the (fst)(Noise Texture) to the snd color of ("MixRGB") & (snd)(Noise Texture) to first allows us now via MixRGB sclae to control the small details (how much we want (to pass throug))

  • fixups
    • small detail noise texture to 2000 (scale)

  • making bump influence color/shadow (6:00)
    • add new (snd)("MixRGB") color node
    • connect ("donut_texture_paint" - 'Color>') => (snd)("MixRGB" - '>Color1')
    • connect (fst)("MixRGB" - 'Color>') => (snd)("MixRGB" - '>Fac')
    • (snd)("MixRGB" - '>Fac')
      • changing '>Color2' manually to a e.g. red or brown
      • change dropdown tyhe from "Mix" to "overlay"
      • will effect the bump influence color/shadow of the donut making it look like its burned

  • some tweaks we could do (10:00)
    • sprinkles
      • amount
      • weight map more random
    • icing
      • color
      • subsurface scattering
    • texture painting
      • with another ("MixRGB") node between texture_paint and the new MixRGB node we can add another overlay/Mix to thin out the white amount

  • silly/fun
    • make icing radio active
    • go to "Material" properties and go to emission and play around
