I’m trying to make a rain close-up, but my result is not good, I can see the grid/mesh (plane subd 8 times), and when I push more the subdiv (11 times), the result si a very thin water skin, not very realistic…
The example in b&w last picture is very good, a lot of contrast and no visible mesh
Any idea how to make it better?

Does it help if you add an extra subdivision modifier after the dynamic paint?
No way to solve this really?
The dynamic paint ripple effect is a little hacky. You could try a fluid sim, but I’m not sure you’d run into less problems.
Perhaps if you bake your dynamic paint output to a texture, rather than directly to the geometry, you could have a bit more control over the mesh resolution, separate from the simulation resolution.
“bake your dynamic paint output to a texure”, sounds smart! I need to try this! But how
I tried to bake, but I have flat color, no waves
I made this tutorial, obviously not the good one for my purpose: https://www.youtube.com/watch?v=F2hkQ9shR0Y

Watch this…it should help you…
and be sure to watch part 2 for the Particle system…
The second one is exactly what I made, but I will look closely the first one in case there is someting for me

If you make a combination of two methods, I think it’ll be the result you want
I recently did A beautiful rain animation in anime style using blender. I just finished creating a tutorial for it today I hope you enjoy it!

WOW this rain generator looks amazing
So I tried the “rain generator”, amazing addon
but for my close-up need it is not ok
So I’m trying a particle rain falling on a fluid box.
I made something wrong because the particle has no effect on the water cube
Rain.blend (2.7 MB)
Unless we purchase the addon your download will not work for us.
And its a new topic (addon not dynamic paint) so you should have started a new thread…
You are right sorry
So back to my first question, how improve quality to not have grid/mesh visible?
the “bake” solution seems to be legit, in “dynamic paint” there is the word “paint”, so somewhere maybe I could have/make a map, then applied the selected ones on a high-res mesh.
I googled to find how to create this but the only tutorial was not ok for my purpose, and I didn’t found another ones
So I’m back to the begining
I tried your link, very interesting !!!
but huge memory killer, even with my RTX 3090 and AMD threadripper 3070
The “dynamic paint” option seems to be the quicker, but how to bake it, to apply it after on a high-res volume?

I don’t have much information because it’s not a function I use myself.
Simulation requires a lot of memory and time, but it is difficult to control in the desired direction.
Yes, that’s why I’m back with the “dynamic paint” option, but I always have this f----g grid visible
-How work the “dynamic paint”? It creates a black and white map somewhere and displace it?
