New video demo and Blend file release !
-> could you make a version that would make irregular ripples ? eg when a shoe steps into a puddle it makes a shoe shaped ripple rather than a ring.
Sure ! Once you will have put your eyes and hands on my blend file you will see that it is easy to create your own templates objects to create ripples of any shapes.
In the example, ripples seem to appear at random, but in fact you can decide exactly where and when they appear, by simply placing vertices at the right location. The core of the animation is a cloud of vertices moving in the Z direction, and supporting a template object.
This setup is very versatile and also includes creations of water spots (or paint spots) and bullets holes.
Here is the Blend file, released under Creative Commons BY 2.0 license. France :
Instructions for use are included in the text window of the blend file.
Select one layer at a time : each layer supports a specific effects. Layer one is best for ripples.
Layer two creates animated texture for bouncing droplets.
In the blend file, always select and look through the camera present on the selected layer.
Render to see the effect with an without compositor (with or without blur).
You can get more rain drops by increasing the number of dots of the cloud, or by compressing the cloud in the Z direction. This second method will shorten the available animation duration, but you can duplicate the cloud vertices at will.
Currently, one thing is not fixed, but not much noticeable : bouncing droplets can’t be shorter that 2 or 3 frames. If it is set to a lesser value, some droplets could be missing.
Feel free to comment.
