I have fixed the rain shift problem (in all the transitions) due to incorrect opacity values and displacement map strength.
I also experimented with water transition based on filter forge tropical water bump map. There are 3 variations.
From mild
1 x 100 = 1 cycle with strength 100
To strong
7 x 300 = 7 cycles with strength 300
There are also 3 extra versions that have x 360 for rotation of normal maps for strange effect.
Thanks,
Tom
