    4D Voronoi is very demanding for the computer, I used 3D Voronoi instead, the Z axis being used for the evolution instead of W.
    This way, I can use it directly on the mesh itself to make a swimming pool, and it's very fast (24 fps, real time).
    For a better effect, you can overlay two of your Voronoi modules with a slightly different mapping.

Afterall, the shadow should exactly be, what the texture offers.

    - - - 4.0 Fix - - -
    Connect the mappings vector to UV instead of normal in the texture cordinates
    (i set my mapping scale to 0.7) so i can see the caustics a bit better
    **I personally dont recommend linking scale and randomness but that is up to you***
    for the RGB mix Shader Replace the Difference to Lighten
    (in the Rgb shader modes you can get different styles that go well with caustics too, i just chose lighten because it went well with the project im working on)
    play around with the color ramp that links the Lighten to the Light output
    (this only works on Cycles)
    Hope it helps! :)

    To increase performance you should definitely use a 3D version of the voronoi and animate it on the Z.
    The advantage of 4D with W is that your could also make it loop with a sine cosine pair.
    Alternative way to do it for eevee would be to use that procedual texture on the object's material with the lamp's coordinates, and multiply it with diffuse->ShaderToRGB.

    • @beautyislikeyeah
      @beautyislikeyeah 3 года назад +1

      Forgive me if this is a massively stupid question but I don't see a place to connect to the Z axis in the node editor in the same way that switching the Voronoi texture to 4d reveals a "W" value to change. Can you point me in the right direction of what you mean by "animate it on the Z"?

    • @syborg64
      @syborg64 3 года назад +1

      @@beautyislikeyeah
      There is a node "Combine XYZ" (Add->Converter->Combine XYZ" that lets you set independently each part of the vector. This gets you a purple socket you can connect into the voronoi input.
      You could then also add a "Seperate XYZ" on your original input coordinates and connect X and Y to the Combine, then set Z to your keyframed value.
      The reason 4D textures let you specify W independently is because blender's vectors are exclusively 3D. whereas actual mathematical vectors have arbitrary size

      @@dukevera4216 the process is simple: bending spacetime curvature onto a 4d hypertorus
      all joking aside, start with an input node and animate it to linearly go from 0 to 1 in the time you want. (here, either match animation length to let it autoloop or actually keyframe it to any whole number and use a modulo by 1 (math node) to bring it down to the 0-1 range)
      Multiply your input by 2*pi, to get it to a range that loops with trig functions
      Connect it to 2 nodes (in parallel) : sine and cosine (math node)
      Seperate your input XYZ vector, keep only the XY,
      Combine inputX, inputY, sine into a vector (combineXYZ)
      feed the combineXYZ and second trig function node (as W) into your procedural texture.
      if you want to change the apparent speed of the animation, multiply the output of both Sine and Cosine by the same value
