    Wider shot. I have been trying to find a reliable method of creating rain reflections, one that is independent from UVW mapping and can be slapped onto any surface. Turns out the answer was in Photoshop's archaic Clouds filter - use that to make a B/W texture, jimmy it in Ps to add contrast, then use it as a specular map with Material Weight and place it on top of the asphalt using the Mix Texture option. Needs some fine-tuning but i'm pleased with this test.

    • Why not a procedural noise as mask ?
      Noise -> Turbulence is similar to ps' cloud filter... play with octaves, global scale, high clip, low clip...      gonzalle
    • BTW, PS' Cloud allow to create seamless textures if your selection size uses 128,256,512, 1024, etc...
      Just to say...      gonzalle
    • I'm just old fashioned and have always worked things out in Ps - cutting my 3D teeth on formZ and Maxwell made me use a more brute force approach.face_melter
    • Finesse comes later when the job is done.face_melter
    • That looks amazingly realistic. I would have tried some noise in the bump channel but this made it look wet.CyBrainX
    • This is crazy but the next thing I looked at was this. I'm not sure if you use Octane or not. https://greyscalegor…CyBrainX
    • ^ having bump on the asphalt combined with specular increases the render time horrendously. I'll leave it until last when everything else is modelled/textured.face_melter
    • I use Vray. Not really a fan of Octane - much more taken with Arnold and its nuts and bolts workflow. I like to know what's going on.face_melter
