i want to make ripple when particle hit surface,
i use collisionUV to calculate where particle hit surface,
but how can i use it to make surface to get ripple.
i use render node wave ,but it dont work

isn't there a tutorial for this on aliaswavefronts website?
failing that - you could have a look at gnomon.com. Theres a tutorial on there for a rock that hits the surface and particles emit from that point. maybe you could use some of this?

In maya5.0 you could create a 2D fluid texture on your object. Make the fluid solver type "springMesh" to create a wave motion with the density values. Take the uv position of the particle hit point and use the setFluidAttr command to add some density to your fluid texture at that uv value, which will create dynamic ripples. ( You can figure out the fluid voxel index by multiplying the uv value by the fluid resolution ).
check out the waterDrops mel script on Highend3d.
It does many things automatically.
