This image shows an attempt at ‘first spots of rain’ using cubic mapping to get a topology effect, If I had a subtractive layer option it would work better, you can see the artifacts but they also look like streaky rain drops so thats fortunate in this case.
The diffuse texture is UV-mapped in this example, which is obviously a photoscan.

To make this effect work better, I would like to use 3D procedurals in a subtractive layer, weightmapped in a way that responds to the topology, maybe using cubic mapped gradients or some kind of directional procedural.
