I create a rain pond in Maya, the result looks fine,but I need to add relection to the pond. when I render the pond , it just nothing shows in the render view. what's the problem with rendering fluid?And how can add reflection to the pond?Thanks very much?
and I got one more question?My pond has ripples over the first 50 frames,it became weaker and weaker as time goes by.so Can I have pondwaker always have effect on the pond?
For reflections you need to either convert fluids->poly, or you can instead create a wake on an ocean.. make the numFrequencies zero on the ocean shader and assign the ocean shader to a plane the size of your pond.. it will now be roughly equivalent. Note that the ocean shader is more reflective when you increase the refractive index. Also you need to enable raytracing and it is a good idea to make the environment ramp on the ocean shader black and instead use real reflections of the true environment.
The wake will generate more ripples if it moves. If you want a stationary wake to generate ripples, increase turbulence on the wake emitter, and play with the turbulence frequency and speed. For steady ripples you could type something like "=sin(time*4)" into the density emission on the wake in the attribute editor(this sets up an expression occillating the emission intensity between -1 and 1).
