hi to all blender gurus,

i am using blender for my final year project, which i'm simulating rain, but in my storyboard i wish to do a close-up on the raindrop all the way till it touches the ground n splash, and followed by the rest of the raindrops.

now i've managed to simulate a basic splash using the fluid function. but i've discovered that by using the soft body self collision feature lets the uvsphere acting all 'watery'.

the problem i faced is that i can't find a way to manually set the soft body settings so that the sphere stays in 1 place n self collide, i've oni manage to do it by using the default, which is 'average', 'min', 'aveminmax' setting. another problem is i can't seem to combine the two physics modifier together(fluid n soft body).

so the question is, 1. what setting should i use for the soft body modifier?
2. how do i create 'splash' with soft body modifier?
3. how do i combine 'fluid' n 'soft body' modifier?

your help is much appreciated, i'm in the dark with this problem now, lol. thanks for reading the long scenario. cheers

hi to all blender gurus,
not exactly my level of expertise, but I'll try to help anyway ;)

1.) I don't think soft bodies are the best solution for your problem. Wouldn't work anyway if you intend to use the fluid simulator -- [cf. 3.)]

2.) you could get the waves on the water surface by using the cloth modifier. Maybe then you could try to figure out the correct values for the soft-body raindrops. Sorry, can't really help you here. Don't even know if cloth and soft-body work together at all...

3.) Short answer: you can't! fluids don't work with soft-bodies (or any of the other physics modifiers)
Especially you can't use a soft-body water drop as a fluid object. That is due to the very nature of the fluid simulator. By setting up a sim you define fluid volumes, obstacles and the domain. While baking the sim the domain becomes the fluid mesh (that's why you can or should delete -- or at least, hide -- the fluid-object after the simulation is baked)

I guess the best way to get what you're looking for is a fluid simulation. In fact, I've seen something similar, made by Mike Pan... [link] (http://mikepan.homeip.net/files.php)
First entry in the list!
Just download and have a look at the .blend-file. Maybe that helps.

Good luck with your project!

wiz4rd, thanks for the advise, that settled part of my confusion, haha, i'll check the link out, thanks again!
