Amerio.Stephane Posted July 29, 2018 Share Posted July 29, 2018 Hello, I'm trying to implement a rotor wash effect on water, like here: The vapor effect is quite "easy" to fake with particles, but I can't find a way to simulate the waves/ripples effect. I'm not trying to have the 3d effect, but rather the "water blown away" with strong ripples. As far as I can tell, the particle_base material can't project ("decal") onto the water. So how should I do that? Thanks. Link to comment
ulf.schroeter Posted July 30, 2018 Share Posted July 30, 2018 there is a water decal option available https://developer.unigine.com/en/docs/2.7.1/content/materials/library/decal_base/#option_water_decal In combination with some radial texture animation and blending this might do the trick Link to comment
Amerio.Stephane Posted July 30, 2018 Author Share Posted July 30, 2018 Indeed, a "Decal" object can project onto the water, but not the particles. This mean I would need to reimplement a small particles management in code, animating the Decals. If this is currently the only solution, I would suggest for future evolution to enable "project on water" for basic particles. Or adding "Decal particles" type to the list of emitted particles. Thanks ! Link to comment
silent Posted July 30, 2018 Share Posted July 30, 2018 Amerio, Please, check the Oil Platform demo (ship. Particles can be rendered into a texture that decal can use to apply on Water. But you need to be careful in terms of performance, since this feature is really CPU/GPU intensive. Thanks!

Amerio.Stephane Posted July 30, 2018 Author Share Posted July 30, 2018 Hi, I've read ship.h and others sources from this demo, and I still can't understand the trailing foam effect is done. I understand what you meant, I just couldn't find in the code how it's done (more documentation in code would be a nice touch, though, also explaining the relation with all the parameters set in the editor) Thanks for your support Link to comment
